752 am chst Friday Oct 9 2015 

pgua Doppler weather radar shows only a few showers moving through 
the marianas waters. The VAD wind profile reveals north winds of 5 
to 9 knots through the lowest 3 thousand feet of the air. 


deep tropical convection is still located to our south at around 
10n. The monsoon trough feeding into Tropical Storm Choi-Wan has 
now morphed into some sort of middle-latitude baroclinic feature. 
Most likely the monsoon trough will now re-form along that line of 
convection. Overall the weather will be pretty laid back the next 
several days...looks like the monsoon trough will move a little 
closer resulting in an increase in cloud cover. The main story 
will be seas...check the marine section for details. 


with ritidian and tanapag buoys both still in the 9 to 11 foot 
range...had to extend the Small Craft Advisory from 6 am to 6 PM 
today. There is still an impressive fetch of north winds on the 
west side of Choi-Wan as it undergoes extratropical transition. 
Both the small craft and high surf advisories may have to be 
extended again...this will be the main forecast problem for the 
day shift. 


Eastern micronesia... 
a weak monsoon trough has reestablished north of micronesia near 16n 
from north of far western micronesia eastward to a tropical 
disturbance centered south of Wake Island near 17n167e. In 
response...a convergent band of fresh west to northwest winds has 
also formed north of Chuuk...Pohnpei and Kosrae between 8n and 12n. 
Meanwhile...the sub-tropical ridge near 25n is also showing signs of 
strengthening. This should gradually cause the monsoon trough to 
sink southward over the next few days. Therefore...expect showers 
and thunderstorms associated with the convergent band to reach Chuuk 
later today...Pohnpei and Kosrae by this evening. 

The monsoon trough curves southeastward from the disturbance near 
Wake Island...passing through a weak circulation centered just north of 
Majuro at 12n170e to beyond 180 at 10n. Diverging surface winds 
south of the circulation center should provide a brief period of 
less shower coverage for Majuro today. As the circulation and trough 
shift southward tonight...converging west to southwest winds near 
the center will bring back wet weather to the capital. A developing 
frontal boundary currently near Japan is going to move slowly 
eastward during this weekend. It might gradually weaken the sub- 
tropical ridge and allow the monsoon trough and circulation to lift 
back northward. If so...improving weather is possible for the entire 
region starting early next week. 

Both latest satellite altimetry and ww3 model output suggest long- 
period north swell generated by former Tropical Storm Choi-Wan has 
built further this morning. This will cause surf to reach hazardous 
levels across Chuuk and Pohnpei states today. Surf should stay at 
hazardous levels through at least Saturday night. 


Western micronesia... 
reasoning for the Chuuk forecast is included in the eastern 
micronesia discussion due to a similar monsoon pattern. 

Despite modest monsoonal winds across the Republic of Palau and Yap 
state...model guidance reveals possible presence of middle-level dry 
air. Latest sounding data from Koror does show a hint of dryness 
between 450 and 300 mb. This trend should support an isolated shower 
regime for both locales through Saturday. As the monsoon trough moves 
southward closer toward 10n...weaker winds near the trough might 
introduce fair weather by Saturday evening. Toward midweek...the 
chance of showers over far western micronesia could increase as the 
circulation currently north of Majuro tracks westward. 

Long-period north swell produced by former Tropical Storm Choi-Wan 
will maintain hazardous surf across the Republic of Palau and Yap 
state through this weekend. Both swell and surf should begin to subside 
early next week. 


Gum watches/warnings/advisories... 
GU...high surf advisory until 6 PM chst Saturday for guz001>004. 

Marianas waters...Small Craft Advisory until 6 PM chst this 
evening for pmz151>154.
