Latest satellite data shows a trough to the north moving toward
the Samoa Island chain. Model trends have been consistent in
bringing this trough over the Islands tonight through Wednesday
night. Additionally, a trough associated with a low pressure 
system to the southwest is forecast to merge with the
aforementioned trough. This pattern will increase the potential 
for flash flooding, particularly on Wednesday. Expect widespread 
showers and variable winds to remain tonight through Wednesday 
night. However, thunderstorm development could produce gusty winds
at times. 

As the low pressure system tracks east, a high pressure system 
building behind it will restore southerly trade winds through the
weekend. Showers will diminish to scattered Thursday night and 
persist through the new week.

Calm seas are currently observed as a winds have weakened across 
the area. Latest wave heights reported by the PacIOOS buoys range
from 5 to 7 feet, which is below advisory criteria. However, 
thunderstorms expected later tonight may lead to hazardous ocean 
conditions. Hence, a small craft advisory remains in effect. 

Model guidance continues to bring a strong south swell into
coastal waters on Wednesday. High surf and strong rip currents are
expected to persist through Thursday before the swell gradually 
subsides over the weekend.
