NWS Forecaster Discussion




Area forecast discussion 
National Weather Service tiyan GU 
420 PM chst Tuesday Sep 2 2014 


Marianas synopsis... 
pgua WSR-88D shows a band of showers in the Rota channel and 
scattered showers east of the marianas waters. Otherwise... 
isolated showers and thunderstorms are moving through the marianas 
waters. The VAD wind profile reveals west winds of 10 to 15 knots 
through the lowest 20 thousand feet of the air. 


&& 


Discussion... 
monsoon trough has built into the forecast zones and should stay 
in the area through Wednesday night. The monsoon trough is 
currently generating isolated showers and thunderstorms within the 
marianas waters. There is an area of scattered showers east of the 
coastal waters that will need to be watched. Just tweaked the sky 
cover to be clearer Thursday through Friday when a ridge is in the 
area then a bit cloudier when the ridge moves off a bit. There 
will be a slight increase in seas Thursday...not enough to trigger 
any advisories though. On Friday seas are expected to subside back 
to current levels then remain there over the weekend. 


&& 


Eastern micronesia... 
ascat wind analysis and satellite images show clouds and showers 
associated with a trade-wind trough are moving across Kosrae state 
this afternoon. The trough will move toward Pohnpei tonight. Weather 
should become drier at Kosrae after Wednesday...but the trough will 
take another day or two to clear the Pohnpei area. Models indicate 
that another trough moving across the date line today will move 
west-northwest across the northern Marshall Islands during the next 
couple of days and it could trigger a few showers and isolated 
thunderstorms at Majuro. Otherwise...mainly gentle northeast to east 
winds are expected across eastern micronesia for the coming weekend. 


&& 


Western micronesia... 
fair weather persists at Chuuk for the near term...but Chuuk weather 
could become unstable toward end of this week as a trade-wind trough 
arriving from the Pohnpei area could trigger showers and isolated 
thunderstorms by about Wednesday night. 


Southwest monsoon flow will dominate weather at Yap and Koror during 
the next couple days. In the longer term...weather could become more 
changeable since GFS in particular indicates the disturbance moving 
from eastern micronesia across Chuuk state in the coming days could 
further develop and move toward western parts of micronesia by about 
Saturday or Sunday. 


No surf advisory has been issued...but the sea conditions at Yap and 
Palau will need to be monitored. Latest ww3 guidance indicates that 
southwest wave components will be short-period and barely into the 
range of a possible surf advisory criteria by late on Wednesday or 
possibly Wednesday night. 


&& 


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