.Short term...

Satellite imagery has shown a mix of sun and clouds over the
American Samoa islands, with only a passing isolated shower over
some areas. WFO American Samoa recorded winds between 10 and 15
mph this morning, but is slowly decreasing this afternoon.

Overall, there is no severe weather forecast for the rest of the
week. Currently, there is a weak trough over the region. The
trough is forecast to remain weak with scattered (30 to 40%
chance) of passing showers through Friday. Flash flooding is not
expected from these showers, if rainfall occurs. Otherwise, winds
are to remain light and variable through the end of the week with
temperatures slightly above normal.

.Long term...

A ridge of high pressure, centered to the southwest of American
Samoa, is forecast move over the islands this weekend and to
remain through early next week. This will likely give more sun
than clouds during the day. Temperatures are expected to fall to
average throughout this time with only a slight risk of passing
showers.

For the next 7 days, there is no risk for tropical development
near American Samoa.

.Marine...

A moderate easterly breeze (10 to 15 knots) remained over the
American Samoa coastal waters last night and throughout the
morning. Seas fell below the Small Craft Advisory levels but
seas remained fairly choppy with elevated swell to keep seas
around 7 feet before slowly easing late this morning and early
afternoon. However, winds continue decreasing to a gentle
easterly breeze for this evening and Wednesday (5 to 10 knots) and
becoming light and variable on Thursday and Friday. Since we have
decreasing winds and weakening swell, seas are to be ideal for
Wednesday through Friday as waves are to subside to around 4 to 5
feet. As a ridge of high pressure moves over the region by Friday
evening, expect similar conditions for the weekend.
