Area forecast discussion 
National Weather Service tiyan GU 
700 PM chst Monday Sep 22 2014 


Marianas synopsis... 
radar shows mainly isolated showers and thunderstorms this afternoon 
but the coverage is gradually increasing and satellite shows areas 
of showers south of Guam near 12n and more showers and thunderstorms 
east of Guam near 148e...which are edging our way. Ascat analysis 
shows a circulation near 11n151e that is associated with invest 
98w. VAD gradient winds are north 5 to 10 knots but surface winds 
range from NE to northwest in the local observations. Buoys show combined 
seas near 4 feet with directional components from west...and 
northeast.

Discussion... 
Special Weather Statement was issued for Mariana islands because of 
the developing disturbance centered southeast of Guam near 11n151e. 
Tracking this disturbance/circulation will be our main forecast 
problem this week. The forecast was upgraded to scattered showers 
tonight and Tuesday based on the areas of showers moving our way 
from the east and northeast. Model solutions have diverged today 
more than previous runs...mainly because the GFS initialized the 
circulation too far northeast...and that makes the forecast more 
difficult. Later forecasts will likely need adjustments as the 
situation becomes better defined in the coming days. 


&& 


Marine... 
marine conditions will deteriorate during the coming days...and 
the monsoon circulation near 11n151e will likely move toward the 
northern marianas. Northeast components of swell and wind waves 
are already arriving along with the small southwest swell that 
persists. Small adjustments were needed for both the wind and 
wave grids. 


&& 


Eastern micronesia... 
a monsoon circulation continues to slowly develop north of Chuuk 
near 11n151e. A monsoon trough curves to near kwajalein at 9n169e. A 
weak ridge extends westward from south of Majuro along 3n to 5n to 
south of Pohnpei. Fair weather will persist at Pohnpei the next few 
days with monsoon-type weather displaced to the north and northwest. 
Low-level convergence will maintain clouds and showers at Kosrae 
tonight and Tuesday. Weather has been fairly quiet today at Majuro 
with a steady west wind. Visible satellite shows showers and a few 
thunderstorms just southeast of Majuro and extending towards the 
date line. These showers are associated with a surface trough that 
will reach the Marshall Islands overnight. Scattered showers will 
reach Majuro tonight and continue through Tuesday. Models show this 
trough will head west-northwest keeping much of the weather just 
north of Kosrae and Pohnpei. Another disturbance is prognosticated to 
develop near the Marshall Islands late Thursday and Friday. Models 
have shown this signal a couple days now so will go ahead and 
introduce more showers and isolated thunderstorms to Majuro for the 
end of the week. 


&& 


Western micronesia... 
the monsoon circulation continues to develop north of Chuuk near 
11n151e. Satellite animation shows wide-spread heavy showers just 
west and north of weno. Much drier weather is found east and south 
of weno. Latest observations show gusty south-southwest winds and 
showers have returned. Scattered showers will taper down to isolated 
around midnight as the bulk of the weather is expected to slowly 
shift north. This will have to be watched closely in case there is 
any shift in the monsoon surge to bring additional showers 
overnight. Weather will continue to wind down through Wednesday as 
the circulation slowly heads north or north-northwest through 
midweek. Drier conditions and lighter winds expected on Thursday. 
Seas were bumped up due to the increased southwest winds. Combined 
seas of 5 to 7 feet tonight across Chuuk state will slowly diminish 
to between 4 and 5 feet by Thursday. 


A benign weather pattern will be in place at Yap and Koror through 
the end of the week. Primary weather feature remains the monsoon 
trough situated just north of both locations and the developing 
circulation north of Chuuk. Isolated showers are expected through 
Saturday with isolated thunderstorms possible Wednesday and Thursday 
at both Yap and Koror due to strengthening southwest winds flowing 
into the developing circulation. Seas will increase 1 to 3 feet in 
response to the increasing winds later this week.
