Showers and Storms in the East; Dangerously Hot and Dry in the West

Scattered showers and storms are expected across portions of the Central and Eastern U.S. through the end of the week. Meanwhile, dangerous heat will intensify across the Desert Southwest and Intermountain West. Hot, dry weather and increasing winds will allow elevated wildfire conditions to return to the northern Intermountain West, where air quality issues persist from ongoing fires. Read More >

Wind observations at WFO American Samoa have remained near 25 mph
for the past several hours, with stronger winds observed at higher
elevations (via Tula Observatory Weather Observations).
Additionally, ASCAT satellite-derived winds showers a 25 to 35
knot south to southeast tradewind regime that was located near
Fiji last night and has since moved closer to the Samoa Island
chain. These observations are consistent with the strengthening
wind pattern discussed in yesterday`s forecast and prompted the
issuance of a Wind Advisory, which will remain in effect through
the weekend.

A strong ridge of high pressure continues to build across the
region and remains the dominant weather feature through the
forecast period. The strongest winds are expected tonight through
Saturday as the ridge intensifies and will remain strong through
Sunday due to a tight pressure gradient between the ridge and a
trough to the north. This trough will likely bring an uptick in
showers from Sunday afternoon through Monday morning. Meanwhile,
additional showers may linger across the area due to moisture from
remnants extending from a winter low to the southeast.

As the high pressure system shifts eastward Sunday night, winds
are expected to remain strong through Monday night before
gradually diminishing during the latter half of the week.

.Marine...
Wave heights continue to build as winds strengthen across the
region. Latest observations at the PacIOOS buoy show wave heights
around 8 to 10 feet, with short peak periods around 8 to 9
seconds. These short periods suggest the current waves are wind-
driven, and are anticipated to peak tomorrow morning at up to 12
feet. Elevated ocean conditions will likely remain through Sunday,
before gradually diminishing below advisory criteria (8 feet) on
Monday. Nonetheless, 20-knot winds will still hold choppy seas,
which could extend the Small Craft Advisory into next Friday. For
this reason, mariners and beachgoers are encouraged to proceed
with caution when traveling or to delay their water activities
until conditions improve.
