NWS Forecaster Discussion




Area forecast discussion 
National Weather Service tiyan GU 
503 am chst Tuesday Sep 2 2014 


Marianas synopsis... 
a weak monsoonn trough is situated north of Saipan...with light 
west to southwest winds across the marianas. Radar shows isolated 
showers in the marianas waters...mainly around Guam and Rota. Seas 
are running close to 3 feet on the buoys. 


&& 


Discussion... 
updated wind and marine grids from GFS and wavewatch...mainly to 
reflect small changes from the previous grids. Overall forecast is 
much the same with light west to southwest winds becoming south 
Wednesday...isolated showers and thunderstorms...and 3-4 feet seas 
through Wednesday night. Drying aloft should kill the thunderstorms 
Thursday on...though GFS is now indicating returning moisture over 
the weekend. Winds should come around to northeast again late in 
the week as the monsoon trough retreats back to the west. 


&& 


Eastern micronesia... 
a surface ridge to the west of Pohnpei is helping to maintain 
pleasant conditions over the state today. Further west...a weak 
impulse embedded within the trade winds will bring an unstable 
pattern to Kosrae today. The impulse is generating scattered showers 
just east of Kosrae this morning...a bit earlier than previously 
anticipated. These showers will continue to develop and spread 
westward across Kosrae around middle morning. Based on latest satellite 
and model run...shower coverage will decrease to isolated tonight 
with most of the convection moving out of the region Wednesday night 
or early Thursday. Pohnpei will begin to see increasing cloud cover 
and convection late tonight as this system approaches the state. 
Drier conditions will return to both Kosrae and Pohnpei Thursday 
into the weekend. For Majuro...a trade-wind convergence zone 
developed to the east and is approaching the Marshalls. This activity 
is expected to reach Majuro this evening with an unstable pattern 
expected to remain over Majuro through the end of the week. Short 
periods of scattered showers are possible through the week. 


&& 


Western micronesia... 
fair weather returned to Chuuk and will continue there through 
midweek. A weak trade-wind disturbance currently over eastern 
micronesia will begin to affect the state Wednesday night and 
Thursday. The primary system affecting western micronesia is the 
well-established monsoonal trough and circulation. This system will 
maintain unstable conditions over Yap state and Palau through the 
next few days. Sounding data from Weather Service office Koror shows a deep layer of 
15 to 25 knots winds through 550mb along with extensive moisture 
throughout the sounding. Gfs40 time height shows this continuing 
for the next few days. Converging winds south of the monsoon trough 
and the abundant moisture at all levels are expected to produce 
scattered showers and isolated deep convection from around noon 
today through Wednesday at both Yap and Koror. Conditions will 
begin to improve over both locations late Wednesday or Thursday. 


Latest altimetry data indicates seas of 4 to 6 feet just west of 
Koror and Yap. Latest model guidance has backed off a bit on swell 
heights. Based on latest data...delayed increase in sea heights that 
would be sufficient to produce surf reaching hazardous levels until 
Wednesday. The situation will continue to be closely monitored.
