A strong high pressure system to the south of the Samoa Islands is
maintaining breezy southeast trades across the area. Expect these
conditions to persist through the week, with passing showers
embedded within the trade wind flow. However, we are currently
monitoring a Tropical Disturbance (TD01F/92P) about 550 miles
northeast of Tutuila. The global model consensus moves the system
in a south southeast direction with gradual intensification. While
this Tropical Disturbance (TD) is currently projected to remain
east of the territory, it is still within our Area of
Responsibility.

A slight westward shift in the TDs track would increase the
potential for heavy rainfall and flash flooding to American Samoa
so it will be monitored closely. Overall, breezy southeast trade
winds of 15 to 25 mph will continue through the week, shifting
more southerly on Thursday as the low tracks southeast. As for
potential tropical development, the greater concern remains east
of the territory, with possible impacts extending as far west as
Rose Atoll at this time. Hence, the Flash Flood Watch remains in
effect mainly for Swains and the Manu`a Islands through the
weekend.
