Synopsis...east to southeast winds and a few showers could be 
found across the marianas this morning. 


scatterometer data from Friday night hinted at a weak trough with 
the axis just west of the marianas. Showers are associated with 
the trough but coverage should remain isolated through the day. 
Southeast winds were observed for a time this morning but east 
winds returned by sunrise. Expect east winds of 10 to 15 miles per hour 
through the day and weekend. Models show a return to dry weather 
by tonight persisting through at least Tuesday. 

A trade-wind disturbance will bring mostly cloudy skies and a 
better chance of showers Tuesday night through Thursday. 


ipan and tanapag buoy data show combined seas of between 2 to 4 
feet this morning. 

The tanapag buoy observed the east swell which will prevail through 
the forecast. The ipan buoy showed the swell coming from a more 
northeast direction. Expect surf of 4 to 6 feet on east facing 
reefs through Monday. 

East winds will pick-up slightly the first half of the coming week 
which should increase combined seas. The increase in seas with 
the east swell will cause a slight increase in surf on east facing 
reefs Tuesday. 

Ww3 model shows a north swell entering the area Sunday night and 
persisting through mid-week. The swell will only be around two 
feet. This swell may not change surf on north facing reefs much 
but should increase the surf on west facing reefs a little. 


Eastern micronesia... 
trade-wind convergence is generating scattered showers and 
isolated thunderstorms across the southern Marshall Islands but 
have pushed just south and west of Majuro. Expected decreasing 
cloud cover through the morning hours at Majuro with dry 
conditions to continue through Monday before another disturbance 
approaches the rmi. A trade-wind convergence and associated band 
of showers and thunderstorms will bring needed rainfall to Kosrae 
in the coming days. Models are in good agreement in keeping active 
weather over Kosrae through at least Monday. However...deep 
convection is expected to remain just south of Pohnpei...similar 
to the current satellite imagery...through the weekend before 
moving northward Monday. 


Western micronesia... 
showers and thunderstorms associated with a trade-wind 
disturbance southeast of Chuuk will affect Chuuk this morning. 
Showers are expected to diminish late this morning with isolated 
coverage returning to Chuuk this afternoon. As stretch of quiet 
weather is anticipated from tonight into Monday as much of the 
convection stays to the south of Chuuk. Convection has dissipated 
across Yap and should stay closer to a surface trough south of 
Koror for the next couple of days. Satellite imagery shows 
dissipating convection over Koror waters. However...another round 
of showers and thunderstorms is possible for Koror tonight as the 
convection cycles. 


Gum watches/warnings/advisories... 
Marianas waters...none.
