   The NWS Storm Prediction Center has issued a

   * Severe Thunderstorm Watch for portions of 
     Central New York
     Central and Eastern Pennsylvania

   * Effective this Saturday afternoon and evening from 225 PM until
     800 PM EDT.

   * Primary threats include...
     Scattered damaging wind gusts to 65 mph possible

   SUMMARY...A fast-moving band of storms will pose mainly a damaging
   wind risk this afternoon.

   The severe thunderstorm watch area is approximately along and 110
   statute miles north and south of a line from 45 miles north
   northwest of State College PA to 20 miles northeast of Wilkesbarre
   PA. For a complete depiction of the watch see the associated watch
   outline update (WOUS64 KWNS WOU7).

   PRECAUTIONARY/PREPAREDNESS ACTIONS...

   REMEMBER...A Severe Thunderstorm Watch means conditions are
   favorable for severe thunderstorms in and close to the watch area.
   Persons in these areas should be on the lookout for threatening
   weather conditions and listen for later statements and possible
   warnings. Severe thunderstorms can and occasionally do produce
   tornadoes.

   Concerning...Severe Thunderstorm Watch 107...

   Valid 012037Z - 012230Z

   The severe weather threat for Severe Thunderstorm Watch 107
   continues.

   SUMMARY...Storms may rejuvenate along the front as it moves into
   eastern Pennsylvania and southern New York, with additional develop
   possible ahead of the front from the Delmarva into New Jersey.
   Damaging winds are likely, with a risk of isolated tornadoes and
   large hail by early evening.

   DISCUSSION...Showers and embedded thunderstorms continue to move
   rapidly east with the cold front, with a relative decrease in severe
   wind gusts compared to earlier in the day, due in part to limited
   moisture. East of the ongoing central PA/NY activity, temperatures
   continue to warm, with a recent trend of a few stations reporting
   rising dewpoints across southern NJ and far southeast PA. 

   Satellite imagery shows increasing CU over parts of MD, though this
   activity is currently shallow. Over the next 1-2 hours, additional
   storms are expected to form from the Delmarva across far eastern PA
   and into NJ, as lift increases. Some storms may become supercells,
   and the tornado risk will also increase through early evening
   coincident with strengthening low-level shear and cooling aloft. Any
   increase in dewpoints will also increase the probability of a
   tornado. Activity may become linear as the cold front overtakes any
   activity ahead of it, with both damaging winds possible across
   southern NY and New England.

   Concerning...Tornado Watch 109...

   Valid 012255Z - 020030Z

   The severe weather threat for Tornado Watch 109 continues.

   SUMMARY...Threat for severe thunderstorms capable of all severe
   hazards, including damaging gusts and embedded tornadoes, continues.

   DISCUSSION...Ongoing convective line has strengthened over the past
   hour as it moves through the more buoyant air mass in place across
   the northern Mid-Atlantic Coast. Modest buoyancy persists downstream
   of the line across far east-central PA, NJ, eastern MD, and DE where
   temperatures remain in the 70s and dewpoints in the mid 50s.
   Vertical shear also remains strong throughout this region, with
   recent VAD profiles from DOX sampling over 70 kt of 0-6 km bulk
   shear. This combination of buoyancy and deep-layer shear should
   support a continued risk for strong to severe thunderstorms.
   Additionally, area VAD profiles at DIX and DOX also show notable
   low-level veering, which could support an embedded tornado or two
   over the next hour or so.

   Recent radar imagery has shown a trend toward forward propagation,
   particularly towards central/southern NJ, where a corridor of
   greater risk for damaging gusts may be developing.

...NWS Damage Surveys for April 1, 2023 Tornado Outbreak and Wind
Event...

.Update 10...Minor adjustment made to the end point and time for
the Cinnaminson-Delran-Moorestown Tornado based on an additional
report of damage. 


.Overview...

A line of severe thunderstorms crossed the region Saturday night,
April 1, 2023. A total of 9 tornadoes have been confirmed (7 in 
NJ, 1 in PA and 1 in DE).

Tornado statistics for Delaware since 1950:

The only other recorded fatality in a tornado in Delaware 
occurred with an F2 tornado on July 21, 1983 near Hartley in Kent 
County.

The strongest tornado on record in Delaware struck on April 28, 
1961 in New Castle. It had an F3 rating based upon it having 
destroyed a 13-inch wall of a warehouse and having tossed large 
doors from the warehouse two blocks away. It also damaged several 
house roofs.

The longest track tornado on record in Delaware struck Kent and 
New Castle Counties on August 4, 2020 during Tropical Storm 
Isaias. It traveled 35.5 miles from the area of Dover to near 
Glasgow and had an intensity of EF2.

The two widest tornadoes previously on record in Delaware were 
the EF2 tornadoes which struck the state on August 4, 2020 during 
Tropical Storm Isaias, both of which had widths of 500 yards.

Historically, Delaware has gone multiple years without any 
tornadoes, only to then have multiple occur in a short time. There
were no tornadoes for about a 7 year period between September 28,
2004 and August 27, 2011. Delaware had 5 tornadoes in a single 
day during Tropical Storm Isaias, the most daily on record. The 
most in a year were 6 in 1992 and 2020.

The Bridgeville-Ellendale Tornado began around 5:59 PM EDT near 
the intersection of Polk Road and Dublin Hill Road where a section
of a small barn roof was blown off. The tornado continued east- 
northeast crossing Seashore Highway. Along this section of the 
damage path, a couple wooden power poles were blown down along 
with several trees uprooted or snapped. On tree fell onto a house 
causing significant collateral roof damage. The tornado continued 
eastward paralleling Newton Road where a farmstead sustain 
significant tree damage. About a half dozen parked semi- trailers 
were blow over along a driveway. Farther east, more tree damage 
and snapped power poles were observed. Near the intersection of 
Precious Lane and Newton Road, a 2 story house was collapsed after
appearing to have slid off its foundation. A small outbuilding 
was also severely damaged nearby. Debris from this area was blown 
several hundred yards east into nearby fields. Another farmstead 
was struck by the tornado as it continued east on Dale Farm Road. 
A large barn had 2 exterior walls blown out and a smaller shed was
blown over. Several trees were also snapped or uprooted on the 
property.

The tornado continued east, crossing a railroad track and 
impacting a Delaware Department of Transportation facility. Along 
the railroad track, a half dozen or more wooden high tension power
poles were snapped and collapsed along with 2 steel high tension 
power poles. This is where the tornado's estimated peak wind 
speeds of 140 mph were reached. The DE DOT facility sustained 
significant damage. A maintenance garage building experienced a 
collapse of an exterior wall and large portion of its roof. 2 
smaller garage buildings nearby experienced several garage doors 
blown out, roofing material removal, and exterior wall damage. A 
building storing road salt had it's roof completely destroyed. The
facility's office building had a few windows blown out, siding, 
and roofing material blown off. Some of the siding material was 
found embedded into the ground downstream where a Delaware 
Environmental Observing System mesonet gauge measured a 98 mph 
wind gust at 3 meters (~10 feet) above the ground at 6:05 PM EDT.

The tornado continued across a field, then crossed US Route 13 
where a few utility poles were snapped. The tornado continued east
into a wooded area where significant tree damage occurred. 
Numerous trees were snapped, one of which fell onto a double-wide 
manufactured home. After continuing through the wooded area, the 
tornado emerged into a field along Sugar Hill Road. A house along 
the road sustained significant roof removal, exterior wall damage,
and blown out windows. A small outbuilding sustained roof 
material removal and several trees near the house were snapped or 
uprooted. The tornado continued across Sugar Hill Road and east 
into another field where 2 irrigation pivots were blown over. The 
tornado emerged into a wooded residential area along Fawn Road 
where the tornado appeared to have intensified. The tornado cause 
significant uprooted and snapped trees in the area as well as 
significant removal of roofing material and blown out windows to 
some of the single-family houses along Fawn Road. Farther east, 
the significant tree damage continued and a large detached garage 
collapsed.

The tornado continued northeast toward the northern extension of 
Fawn Road where more significant tree damage occurred. A single 
story single family home appeared to have slid off its foundation 
and collapsed. A few other homes sustained roofing material and 
other cosmetic material blown off. The tornado continued east into
another wooded residential area along Quail Hollow Road where 
mostly significant tree damage occurred. Numerous trees were 
snapped or uprooted. One snapped tree fell into a house causing 
significant collateral damage. On large detached garage was 
severely damaged with exterior walls and roof collapse near 
Tuckers Road And Quail Hollow Road.

The tornado moved northeast from this area into a wooded area 
just south of Tuckers Road, emerging into an open field. This was 
the point where the tornado reached its maximum with of about 700 
yards (~0.4 miles). The tornado struck a small farmstead along 
Tuckers Road. The house appeared to have slide off its foundation 
and collapsed. 2 barns on the property were completely destroyed 
along with snapped trees and power poles. Farther east, several 
homes sustained damage from fallen trees and wind blowing off roof
material. A few irrigation pivots were blown over in this area. 
Numerous trees were snapped or uprooted along Owens Road and 
Sharps Mill Road near Tuckers Road. Just east of Tuckers Road, a 
single family house sustained significant structural damage. A 
large section of roof was blown off and an exterior wall was 
partially blown out. Several windows were blown out and the vinyl 
fencing on the property was almost completely blown away. A few 
more trees and minor cosmetic damage to structures occurred a few 
hundred yards east of Tuckers Road as the tornado continued 
northeast. Another residence was struck by the tornado on Tuckers 
Road where a large portion of exterior wall along the attic was 
blown off. The home's chimney was also blown off and a few windows
were blown out. A detached garage on the property had its roof 
almost completely blown off. A chicken house behind the residence 
had a small portion of its roof blown off. Some trees were 
uprooted along a tree line before the tornado moved into a large 
and inaccessible wooded area.

The tornado appeared to have maintained a fairly steady intensity
as it continued northeast toward Ellendale while crossing several
roads. The tornado crossed Oak Road, B and R Road, Oakley Road, 
Union Church Road, and Beaver Dam Road. Along these road 
crossings, the tornado produced consistent tree damage and some 
minor cosmetic damage to some homes. More notable areas of damage 
include: a large chicken house along B and R Road was severely 
damaged with some collapse of the northern end of the structure; A
house along Oakley Road had an exterior garage wall pushed 
inward; more significant tree damage was also noted along Oakley 
Road; and a small portion of a single family house was blown off 
on Beaver Dam Road.

The tornado crossed US Route 113 into Ellendale where sporadic 
tree damage occurred in a residential area along Sharons Road. An 
entire attached garage roof and walls were blown off on a single 
family home on Pine Oak Street near Sharons Road. Some other 
houses sustained roof material blown off in this area. The tornado
crossed Beach Highway/Main Street near Old State Road where some 
minor tree damage occurred and some shingles were blown off of a 
few homes. The tornado crossed Washington Avenue and McCaulley 
Avenue where a small portion of roof material was blow off of a 
free standing garage. The tornado began to weaken considerably 
moving northeast of downtown Ellendale. It crossed Ponder Road 
where some roof material was blown off of a automotive service 
building. The tornado continued into a wooded area then crossed 
Holly Tree Road emerging into a field. The tornado circulation 
dissipated around 6:19 PM EDT just after turning over an 
irrigation pivot near Hummingbird Road and Benson Road.

One fatality occurred from this tornado, but no other known 
serious injuries occurred.

A tornado formed from along an eastward moving rotating supercell
within a line of thunderstorms and made initial touchdown near 
Patterson road, off of West Commodore Road, in Jackson Township 
and continued east for approximately a 3/4 mile long and 200 yard 
width path across the residences on the north side of Stonehenge 
Ct and along West Commodore Blvd, before going across the 
residences and businesses across Wright Debow and Hamilton Rd. 
Dozens of large hardwood and softwood trees were snapped or 
uprooted in a convergent pattern, power poles downed or snapped, 
fences demolished, and sheds, small outbuildings, and dumpsters 
flipped or moved. Despite the significant tree damage, generally 
only minor siding and roof shingle damage was noted. This damage 
was consistent with EF1 winds of 90 to 110 mph. 

The tornado then likely strengthened to its greatest intensity as
it continued east, across a cleared and paved area, to a newly 
built large warehouse development. The southern half of the 
warehouse, made up of several 3 story concrete pre-fab tilt-up 
walls, both on the east and west side, tied together with metal 
roofing system above, collapsed in an eastward direction. Based on
the degree of damage and construction this was determined to be 
high end EF2 winds of 120 to 130 mph. In addition dozens of hard 
and soft wood trees on the south and southeast side of the 
building and east side parking lot were uprooted or trunks snapped
laying in a E/NE direction. 

The tornado continued on, now in an east southeast direction, for
about 3/4 mile with about 200 yd path width, just north of 
GasTime, across Diamond Road and back along West Commodore road, 
and into the residences around Indiero Lane and Oaktree Lanes. The
most extensive tree and powerline damage was seen along West 
Commodore Road, with hundreds of mature hard and soft wood trees 
uprooted or snapped in a convergent pattern, numerous power poles 
downed or snapped, as well as roofing and insulation debris from 
the warehouse being littered along the way. The tree damage along 
part of West Commodore Road was consistent with winds of 100 to 
120 mph. The tornado appeared to be weakening to EF0 as it entered
the residences around Indiero Lane and Oaktree Lanes, south of 
West Commodore, with the tree damage path becoming scattered and 
narrowing to 100 yards, and only minor siding and roof shingle 
damage noted. The tornado likely occluded just before reaching the
Land O Pines Mobile Home Park, where the tornado path ended.

A tornado formed along an eastward moving rotating supercell 
within a line of thunderstorms and made an initial touchdown on 
the north side of Palomino Drive. A 100 yard wide path of dozens 
of large hardwood and softwood trees were snapped or uprooted in a
convergent east to northeast pattern between the north side of 
Palomino Drive and the high tension powerlines paralleling to the 
north. In addition to the extensive tree damage, numerous fences 
were demolished with moderate roof and shingle damage to houses on
the north side of Palomino Drive. The path of tree damage 
continued east southeast, across N New Prospect Rd, and along the 
north and northeast periphery of the newly built Paragon apartment
complex. The degree of tree and home damage is consistent with 
winds of 100-120 mph. 

The tornado continued east southeast down to the intersection of 
Larsen Road and Maplewood Place. Several large hard and soft wood 
trees were snapped or uprooted in a convergent pattern, and power 
poles downed, on either side of Larsen at this intersection. The 
tornado tracked east southeast across the residences along the 
east side of Maplewood and the northeast section of Dogwood Rd, 
with about a 150 yd width path of dozens of large trees snapped or
uprooted in a convergent pattern, power poles downed or snapped, 
fences demolished, and sheds flipped or moved. Despite the 
significant tree damage, generally only minor siding and roof 
shingle damage was noted. This damage was consistent with EF1 
winds of 90 to 110 mph. The tornado likely moved southeast from 
here across a shallow NE to SW cleared valley area along the 
Monmouth/Ocean county border with transmission lines running 
through. No damage was noted to the transmission lines or the 
metal truss towers.

The tornado then likely strengthened to its greatest intensity as
it continued east southeast from the clearing to the residences 
on the southwest corner of Spicy Pond Rd. Numerous large trees 
were snapped or uprooted in a 300 yd long and 150 yd wide 
convergent pattern, fences demolished, and several houses having 
minor to moderate siding, gutter, awning, deck and roof shingle 
damage. The worst damage occurred to a house facing to the 
southwest on the southwest corner of Spicy Pond Road, whose whole 
roof was lifted and tossed into their backyard and immediate 
neighbor backyards. Some of the debris, including a larger roof 
rafter was lofted about 125 yards, impaling the roof and second 
floor of a house on the east side of Addison Road. In addition, 
some siding from the house was impaled into the siding of the 
neighboring house to the north, with insulation and siding debris 
littering the neighborhood for about 200 yds to to the east 
southeast. Based on the degree of damage and construction this was
determined to be EF2 wind damage of 110-120 mph. The tornado 
likely quickly occluded after passing Addison Rd, ending its short
path.

Survey Summary: 

A tornado formed along a line of thunderstorms and made initial 
touchdown in Cinnaminson, NJ, near the intersection of Riverton 
Road and Woodside Lane where multiple trees were snapped and 
uprooted. It then traveled east-southeast towards Cinnaminson High
School and Eleanor Rush Intermediate School, where the damage 
path expanded to around 0.3 miles wide or about 520 yards, 
spreading across much of the surrounding neighborhood where 
numerous trees were reported down. The strongest wind damage 
occurred near the intersection of Wynwood Drive and Locust Lane 
where a majority of the roof covering was peeled off a single- 
family home. The tornado continued east-southeast across US HWY 
130 into Lakeview Memorial Park where a large swath of softwood 
trees were either uprooted or snapped at the trunk. Continuing 
east-southeast, the damage path continued through the 
neighborhoods surrounding New Albany Road and Endicott Ave, moving
towards the communities near Ravenswood Park, uprooting and 
snapping multiple trees. The tornado then crossed Haines Mill Road
in Delran where it grew to its greatest width of approximately 
0.3 miles or 600 yards. After persisting east- southeast and 
crossing Bridgeboro Road, it likely pushed through Esther Yanai 
Preserve where the damage path was lost due to lack of road 
networks in the preserve. Minor tree and limb damage was observed 
again near John Pryor Field in Moorestown. More widespread damage 
was then found near the intersection of Hartford Road and 
Worthington Drive with multiple softwood trees uprooted or 
snapped. The wide swath of tree damage continued over to Dominion 
Drive with numerous trees uprooted or snapped and left leaning on 
utility lines along Borton Landing Road. It is likely at this 
point the tornado began to occlude and wrap up. Additional snapped
branches and minor damage to veneers and siding was found along a
narrow strip of Country Club Drive in the Laurel Creek Country 
Club neighborhood. The tornado then caused minor damage to some 
roof shingles on a home on Augusta Drive. Near Centerton Road, the
tornado snapped the top of a utility pole and damaged the top of

A tornado formed from an east southeast moving rotating supercell
within a line of thunderstorms and made a brief touchdown on the 
National Guard Training Center Grounds in Sea Girt, NJ.

The tornado likely developed over Stockton Lake and tracked east
southeast over the New Jersey Youth Challenge Academy. The entire
half dome, wood frame, shingled roof of the southwest facing 
academy building, about 25 yards wide and 50 yards long, was 
lifted and thrown eastward. The debris was lofted and strewn for 
about 250 yards to the east northeast in a tapering, semi-circled
debris drag marks and layout pattern. In addition one tree was 
uprooted and laid in an east northeast direction. The tornado 
likely lifted as it tracked east across the parking lot and open 
grass fields. Based on the degree of damage and construction this
was determined to be EF2 wind damage of 110- 120 mph, with debris
and downed tree pattern indicative of a tornado.

Isolated large tree damage was noted upstream of the National
Guard Training Center starting at the corner of Sea Girt Ave and 
Route 35, working east southeast down Sea Girt Avenue, across the
intersection of Atlantic and Broad Street, to Pearce Avenue and 
behind Manasquan Fire Department. There is not enough evidence in
the damage indicators to classify as part of the tornado track, 
and so more likely associated with a narrow developing rear flank
downdraft of 70-80 mph, that shortly later lead to tornado 
formation over Stockton Lake. A couple of other notable impacts, 
400 yards to the north of the New Jersey Youth Challenge Academy 
building, a couple of bleachers were pushed about 40 yards east 
northeast from their starting position across the Athletic field.
Once again, not enough supporting evidence for this being a 
separate EF0 tornado, but instead, more likely due to straight 
line winds or gustnado of 70 to 80 mph winds.

Finally, a small bleacher was overturned at the Manasquan Little
League Fields, about 600 yards southeast of New Jersey Youth 
Challenge Academy and right before the ocean beachfront, again 
consistent with straight line winds of 70 to 80 mph. For 
reference, the Sea Girt observing site measured a similar 71 mph 
gust at this time.

Emergency Management, Army National Guard Leadership, Monmouth 
County Emergency Management and New Jersey State Police for their

Survey Summary: 

A tornado developed as a line of storms moved through lower Bucks
County. Several trees were uprooted and snapped on the south side
of Wrightstown Township. As the tornado progressed southeast near
Swamp road, additional tree damage occurred in residential areas 
as well as on the Bucks County Community College Campus. The 
maximum estimated wind speed was associated with damage observed
on the north side of Newtown where a roof facade was blown over 
on a portion of a strip mall building. Additional tree damage was
observed in downtown Newtown. The continuous path of damage ended
in the vicinity of the Newtown Cemetery.

After a straight line wind event upstream toward Bordentown along
Ward Avenue, a QLCS tornado developed in the village of 
Crosswicks around 7:08 PM EDT. Much of the damage in Crosswicks 
was primarily tree damage with numerous trees uprooted or snapped.
Additional straight line wind damage occurred south of the 
village that was not directly related to the tornadic circulation.
The tornado moved east out of the village just north of Ellisdale
Road where fairly significant tree damage continued on 
residential properties. The tornado moved into an inaccessible 
wooded area along Crosswicks Creek where it crossed into Hamilton 
Twp in Mercer County. It emerged along a tree line near the back 
of the Sawmill YMCA property where it continued east toward the 
intersection of Sawmill Road and Iron Bridge Road. Near this 
intersection, several trees were uprooted.

The tornado continued east along Sawmill Road toward Extonville 
Road Where additional trees were uprooted. The tornado dissipated 
in a field around 7:11 PM EDT east of Extonville Road where it 
crossed just over the Monmouth County boarder into Upper Freehold 
Twp. No additional tornadic damage was observed east of this field
across Ellisdale Road until the next tornado began near Walnford 
Road.

A new QLCS tornado developed just west of a neighborhood on 
Walnford Road southeast of Allentown. The most significant damage 
from the tornado occurred to properties within the neighborhood, 
especially those along an open field to the southeast. The tornado
was also near its widest point in this area. Numerous trees were 
uprooted or snapped within the neighborhood. A few homes sustained
removal of roofing material, siding removal, windows blown out, 
and a couple garage doors blown out. Damage in this area was 
consistent with wind speeds estimated to be near 110 mph. An 
irrigation pivot was blown into a fence separating the 
neighborhood and the field where it was toppled over, partially 
into some residential yards.

The tornado continued eastward across the field toward Allentown 
Davis Station Road where another shorter irrigation pivot was 
overturned. Along the road, several trees were snapped or uprooted
near and northwest of the intersection with Polhemustown Road and
Holmesmill Road. A wooden power pole was also leaning in the 
direction of the tornado's motion. The tornado continued east 
along Allentown Davis Station Road where more mainly minor tree 
damage occurred. At the traffic circle intersection with Sharon 
Station Road, several road signs were blown down in various 
directions. The tornado moved east-southeastward into a field just
south of a farmstead and north of Davis Station Road. The tornado
entered another wooded residential area near the intersection of 
Davis Station Road ans Harvey Road where more significant tree 
damage occurred and the tornadic circulation widened. The tornado 
moved east across Meirs Road where numerous trees were snapped or 
uprooted on residential properties, once of which fell onto power 
lines.

The tornado moved east toward a residential neighborhood along 
Long Acre Drive where some additional tree damage occurred. The 
tornado moved east of the residential area across a tree line and 
then dissipated in an open field along Emleys Hill-Prospertown 
Road.

A tornado formed along a line of thunderstorms and made an initial 
touchdown just east of Llewellyn Avenue and south of US HWY 40 in 
the Richland section of Buena Vista Township. This was a heavily 
forested area with large branches snapped. The tornado continued 
east, moving parallel to Landis Avenue, and into Mays Landing. As it 
moved into Mays Landing, the tornado produced its strongest wind 
damage, where a roof was partially lifted off a single-family home. 
Numerous trees on the property had large branches broken, with an 
area of uprooted trees just to the east of the home. 

The tornado continued to progress eastward along Landis Avenue, with 
large amounts of uprooted trees, snapped trunks, and broken 
branches. Damage remained mainly confined to the north side of the 
road. The tornado then crossed Estelle Avenue, where broken branches 
and snapped trunks continued for about another 200 yards into the 
densely forested area.
