Weather Update: High surf,wind watch, flash flood watch all in effect
Pago Pago, AMERICAN SAMOA — After a night of heavy showers with winds predicted to gust to 35 mpg, you can expect, today, Sunday, Feb. 24, occasional showers with highs in the lower 80s. Lows in the mid 70s. North winds 35 to 45 mph with higher gusts.
Monday through Wednesday the territory will experience occasional showers with lows in the upper 70s, highs in the lower 80s and north winds 20 to 30 mph, diminishing to 15 to 20 mph Tuesday night.
The latest model shows an active trough oriented northwest to southeast, remaining across the islands through the new week. The ridge to the north and a broad area of high pressure to the south will keep this trough along the Samoan Islands through at least midweek.
This active trough was expected to bring occasional showers with embedded thunderstorms over the Samoan Islands through Saturday night.
Tropical Disturbance 11F (TD11F- 95P) was expected to move north of the area through the night, then dive south towards the Samoan archipelago Sunday night. TD11F is also expected to bring 30 to 35 knot winds with higher gusts Sunday through Sunday night.
With this scenario in place, TD11F will bring more rain and increased winds over the
islands for the short term. This will likely prompt continuing wind advisories that could be elevated to a warning if conditions are met.
More rain is forecasted to move into the area as TD11F (95P) migrates southward and away from the area. You can expect active weather to prevail through the rest of the forecast.
Flash flooding and mudslides are also possible along low-lying areas, steep slopes and mountainous areas. Expect winds to increase to breezy conditions through at least Sunday night then decreasing to moderate on Monday.
