NWS Forecaster Discussion




Area forecast discussion 
National Weather Service tiyan GU 
630 am chst Wednesday Sep 17 2014 


Marianas synopsis... 
radar shows areas of rain and isolated embedded thunderstorms across 
the coverage area. Satellite shows areas of deep convection over the 
forecast zones. Ascat analysis indicates the circulation associated 
with invest area 96w is near 12n137e and drifting toward the west. 
VAD gradient winds are south-southwest at 10 to 15 knots. Local buoys 
show combined seas of 4 to 5 feet with mixed directional components 
from southwest...east-northeast and south. 


&& 


Discussion... 
the wet monsoon-type weather will persist today as invest area 96w 
gradually develops and drifts away westward and then northwestward. 
Rainfall will be heavy today for some locations...especially near 
Rota this morning. Most models indicate relatively drier weather 
will arrive by tonight with a light wind regime developing through 
the weekend. 


&& 


Marine... 
sea conditions will be mixed next few days with moderate rip current 
risk along most reefs. Adjustments were made to wave grids based on 
the ww3 wave model which indicates several different smallish swell 
components will affect sea conditions besides the basic east-NE and SW 
swells already in the forecast. Refreshed wind grids with latest GFS 
model data. 


&& 


Eastern micronesia... 
an mesoscale convective system developed overnight at Majuro producing showers and a few 
thunderstorms for much of the nighttime hours requiring a forecast 
update. Over 4 inches of rain has fallen so far this morning. A 
few more showers are seen near Kosrae and Pohnpei along surface 
troughs near both locations. Scattered showers at Kosrae and 
Majuro this morning will become isolated around noon today as 
weather gradually improves. GFS still shows a drying trend over 
the next 24 hours across the region as the broad trough over the 
Marshall Islands shifts west. Am hesitant to follow this trend 
considering the showery weather over the last 24 to 36 hours. Will 
meet halfway maintaining mostly cloudy skies and isolated showers 
and thunderstorms at least through Thursday night at both Majuro 
and Kosrae. Weather appears to be a bit more benign at Pohnpei in 
the near term. Day shift will have to closely watch here as well 
due to the proximity of a surface trough. By Friday...models show 
a broad monsoon-type trough developing along 10n bringing winds at 
all locations to south or southwest. Additionally...a wetter 
pattern is prognosticated to begin with this feature. Will have to watch 
how this evolves the next few days for a finer-tuned forecast. 


&& 


Western micronesia... 
dry weather remains in place at Chuuk this morning. Infrared satellite 
shows isolated showers and thunderstorms near Pohnpei that will 
reach Chuuk tonight and continue through Thursday night. Drier 
weather will return for the end of the week. As mentioned in the 
eastern discussion...a monsoon-type pattern is prognosticated to develop 
by Saturday along 10n. Will have to wait a few more days to see 
how it influences the weather. 


The broad monsoon circulation is centered north-northwest of Yap 
near 14n136e. This circulation is now the subject of a tropical 
cyclone formation alert by the Joint Typhoon Warning Center. 
Scattered showers are gradually pulling away from Yap and Koror 
with the bulk of the weather now northwest of both locations. 
Forecast reduces showers to isolated around noon. However...infrared 
satellite shows a cluster of showers west of Yap between 140e and 
145e. This is slowly creeping west. GFS picks up on this...showing 
showers slowly subsiding by afternoon with this feature. Day shift 
will have to keep a watch on this to see that this happens 
according to the forecast. Conditions will continue to dry out 
through Thursday and Friday. Weekend forecast for both Yap and 
Koror looks erratic in the models with light and variable wind 
flows...but generally dry. 


Day shift will also have to keep a watch on sea heights near Koror 
and Yap. As the monsoon circulation gradually strengthens...winds 
will maintain higher swell across the region.
