Hurricane Andrew Lifecycle

Andrew's journey began as a tropical wave departing the West African coast on August 14th.  By August 16th, the wave was organized enough to be classified a tropical depression, and then a tropical storm on the 17th.  Andrew tracked west to northwest across the Atlantic around the south side of a ridge of high pressure. An upper low near Bermuda initially kept Tropical Storm Andrew from developing stronger as convection around the storm was sheared away from the low-level center. Eventually, the upper low weakened and retreated north while a deep ridge of high pressure over the southeastern U.S. strengthened and turned the system back to the west.  

With the upper level ridge of high pressure firmly established across the Eastern United States and Western Atlantic, Andrew reached minimal hurricane intensity early on the 22nd and began to accelerate westward. During the next 36 hours, Andrew explosively intensified from a category one to a category five hurricane by mid-day on the 23rd. During this period, the central pressure dropped 72 millibars, allowing the storm to reach its maximum intensity of 175 mph (150 knots) with a minimum central pressure of 922 mb (27.23 inches). The ridge held steady over the next couple of days, driving the small but very intense hurricane west. Andrew weakened slightly to a category four hurricane while crossing the Bahamas, but re-intensified to a category five while crossing the Gulf Stream east of the Florida peninsula. The storm slammed Dade County, Florida (south of downtown Miami, near Homestead) around 5 AM EDT on August 24th with winds of 165 mph (145 knots) and a minimum central pressure of 922 millibars (27.23 inches). The Miami, FL WSR-57 radar (located on the roof of the National Hurricane Center) was destroyed shortly after the last complete scan of Hurricane Andrew at landfall. The newly installed Melbourne, FL WSR-88D captured Andrew's landfall and trek across South Florida.

Andrew weakened slightly to a category four while traversing South Florida for a few hours, eventually emerging over the Gulf of Mexico.  For the remainder of the 24th, Andrew continued to move quickly west-northwestward with little change in strength.  By the late morning hours of the 25th, an eyewall replacement cycle completed, with a much larger eye emerging on visible satellite imagery as Andrew slowly strengthened once again.  Andrew reached 145 mph (125 knots) and a minimum central pressure of 937 millibars (27.67 inches) during the late afternoon and early evening hours of the 25th, about 50 miles south of the Southeast Louisiana coast.  Andrew began to slow down and move northwest for the remainder of the 25th as an approaching upper-level trough began eroding the western side of the ridge.  

Hurricane Andrew continued to weaken during the early morning hours of August 26th as the eye paralleled just offshore the South-Central Louisiana coast. Andrew finally made landfall near Point Chevreuil (about 20 miles west-southwest of Morgan City) at 3:30 AM CDT as a category 3 hurricane with winds of 115 mph (100 knots) and a central pressure of 956 millibars (28.23 inches). The newly installed Houston, TX WSR-88D captured Andrew's landfall across South Central Louisiana. See the Radar and Satellite Animation Imagery section for the animation sequences of Andrew

After landfall, Andrew continued on a more northerly track while weakening across South-Central Louisiana, traversing most of the Atchafalaya Basin.  Andrew was downgraded to a tropical storm by noontime, northwest of Baton Rouge, Louisiana. The storm was further downgraded to a tropical depression by midnight on the 27th, just southwest of Jackson, Mississippi.  Click here for an interactive track of Hurricane Andrew.

Impacts in Southeast Louisiana and Southern Mississippi

Hurricane Andrew caused 8 deaths and an estimated $1 billion in damages in Louisiana. Combining this with Florida, Andrew directly caused 23 deaths in the U.S. and indirectly caused 39 more, with $27.3 billion in total damages. For more detailed information on the damages across Florida, Louisiana, and Mississippi, see the Storm Data Excerpt for Hurricane Andrew.

 

Maritime and Energy Impacts in the Gulf of Mexico, Mississippi River, and Atchafalaya Basin:

240 oil and gas production platforms were damaged over an 85 mile wide area off the central and southeast Louisiana coast according to the U.S. Mineral Management Service.  Estimated losses amounted to $200 million.  The U.S. Coast Guard found the bodies of 6 crewmen from the fishing vessel Lucky Lee floating in the Gulf of Mexico about 5 days after Andrew made landfall.  The USCG rescused 4 people from the 65 foot Night Stalker that floundered in high seas and strong winds about 50 miles south of Houma around 1130 AM CDT on August 25, 1992. 

Two ocean going freighters the Formosa Three and the Probo Hawk were aground near Vacherie.   Two towboats, the MV Harrison and the Jolly Jack, foundered and sank near St. Francisville while attempting to retrieve breakaway barges; 10 crewmen were rescued.  The Mississippi Queen steamboat evacuated 250 passengers at Baton Rouge around 10 AM CDT on August 26, 1992 because it was having difficulty remaining at its berth and due to the break away barges in the Mississippi River.

An upwelling of bottom sediment rapidly depleted oxygen in the basin and along the shallow coastal waters of Terrebonne and Lafourche Parishes.  An estimated 187 million freshwater fish were killed in the Atchafalaya River basin and along Bayou Lafourche.  9 million salt water fish and a large number of oysters were killed in the shallow waters of Terrebonne and Lafourche Parishes.  Total losses to the fish and wildlife industry were estimated to be $266 million. 

Impacts to St. John the Baptist Parish:

A strong tornado moving rapidly west on an intermittent 9 mile path through Laplace and Reserve between 910 PM CDT and 920 PM CDT, killed two people and injured 32.  Both fatalities, a 2 year old girl and a 63 year old man, occurred in their Belle Pointe subdivision homes in Reserve.  A joint damage survey conducted by the St. John the Baptist Parish Office of Emergency Preparedness and the National Weather Service indicated that 66 homes and 33 mobile homes were destroyed; 56 homes or mobile homes sustained moderate damage; and 130 homes or mobile had minor damage.  25 businesses were either destroyed or sustained moderate damage.  This included the River Parishes Hospital which had its roof damaged by the tornado and had to be evacuated.  7 public buildings including 2 schools were damaged.  Estimated damages to homes and mobile homes were $6,726,250; businesses, $3,428,500; public buildings $1,957,500.  Agricultural losses to the sugar crop were $1 million, and $100,000 to the soybean crop.

Impacts to Lafourche Parish:

A 5.6 to 6.2 foot NGVD storm tide washed away about 500 feet of LA 1 below Leeville and about 75% of LA 3090 (Port Fourchon Road).  Estimated damages to Port Fourchon including rebuilding LA 3090 were $2,200,000.  Approximately 20 homes and 32 mobile homes were destroyed; 154 homes and 66 mobile homes had moderate damage; 589 homes and 68 mobile homes received minor damage.  The bulk of this damage was in the south part of the parish especially in the towns of Golden Meadow, Leeville, and Port Fourchon.  Nicholls State University in Thibodaux suffered a $1 million loss when strong winds damaged 28 roofs which allowed wind driven rain to soak the interior of these buildings.  

Impacts to Terrebonne Parish:

A 5 to 7 foot NGVD storm tide inundated the towns of Cocodrie, Pointe Aux Chenes, Montegut, Dulac, and Chauvin.  The Louisiana University Marine Consortium in Cocodrie was inundated by 5 feet of water; in addition, it sustained major wind damage when strong winds below in heavy plate glass windows.  The Grand Caillou and Montegut elementary schools were flooded by storm tides.   Approximately 255 homes and 547 mobile homes were destroyed; 1,726 homes and 290 mobile homes sustained moderate damage.  Strong winds did an estimated $1 million damage to 201 bed L.J. Chabert Hospital in Houma when part of the roof was torn off and wind driven rain soaked the interior; 70 patients were evacuated.  In addition, several businesses in Houma sustained heavy wind damage.  Andrew caused an estimated $350,00 to Terrebonne Parish schools; three schools needed major roof repairs.
