.Short term...

A Flash Flood Watch remains in effect until tonight as a trough

lingers in the area. Latest satellite data shows thunderstorms and

showers focused south of the Samoa Island chain, with some

convection over the Islands. The upper air sounding from this 

afternoon holds a moist and unstable profile, suggesting shower 

development and thunderstorm activity are still possible for the 

next 24 hours. Expect widespread showers to persist for tonight,

gradually diminishing to numerous Tuesday morning. By midweek, 

expect scattered showers with a light breeze as the trough exits 

the region. 



.Long term...

No significant weather systems are expected to dominate in the

area through Friday. Hence, expect variable winds up to 10 mph and

scattered showers for this duration. By the weekend, a strong high

pressure system building over Australia will shift winds 

southeast at 10 to 15 mph.

.Marine...

A south swell and nearby thunderstorms will hold elevated seas

through midweek. Current wave heights observed at the PacIOOS 

buoys indicate waves within the 6 to 8 foot range. These heights

are within small craft advisory thresholds, which will remain in

effect until Wednesday. As these swells subside by Thursday,

expect lower wave heights to persist through the weekend.
