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 >

Current ASCAT satellite-derived winds show a broad 25 to 30 knot,
or roughly 25 to 35 mph, south to southeast tradewind regime
across the Samoa Island chain. These stronger winds are also
reflected in the latest upper air sounding, which showers a
tradewind inversion along with a moist surface layer. Showers
embedded within the tradewind flow are evident, and scattered
showers are expected to persist through the weekend. A Wind
Advisory remains in effect as strong and gusty winds continue
across the territory.

A strong high pressure system to the south remains the dominant
weather feature across the region. The strongest winds are
expected Friday through Sunday as the high pressure lingers and
maintains its strength. A trough to the north that was expected to
shift close to the Islands Sunday night, model guidance now keeps
it farther north and away from the Samoa Islands. Therefore,
showers through the weekend will mainly remain embedded within the
tradewind flow.

As the high pressure system shifts eastward Sunday night, winds
are expected to remain strong through Monday night before
gradually diminishing later in the week.

Hazardous ocean conditions continue across coastal waters as
strong trade winds maintain elevated seas. Wave heights reached as
high as 16 feet overnight and are expected to remain elevated
through the weekend due to the prolonged tradewind event. In
addition to wind-driven seas, a south swell is evident with peak
periods reaching around 13 seconds.

The combination of elevated seas, strong winds, and the south
swell is producing extremely hazardous conditions for mariners and
beachgoers. A High Surf Warning remains in effect as dangerous
surf impacts south-facing shores, while strong and life-
threatening rip currents are also expected. Elevated ocean
conditions will persist through the new week before gradually
improving by midweek.
