NWS Forecaster Discussion




Area forecast discussion 
National Weather Service tiyan GU 
428 PM chst sun Oct 26 2014 


Marianas synopsis... 
radar shows shower coverage has increased to scattered with isolated 
thunderstorms during the afternoon. Ascat analysis indicates a shear 
line lies across the forecast zones...and a weak circulation is just 
south of Chuuk. VAD gradient winds are NE about 15 knots. Saipan buoy 
shows a persistent NE swell around 7 feet. 


&& 


Discussion... 
increased shower forecast to scattered for tonight and extended 
isolated thunderstorms through Friday. The weak circulation just 
south of Chuuk along with a surface trough extending northeast of 
Chuuk is expected to move slowly toward west in the coming days. 
Most models indicate a wet pattern of east winds veering southeast 
by about Wednesday. A few thunderstorms along with some times of 
scattered showers can be expected across the marianas this week. 
The circulation just south of Chuuk will also need to be monitored 
as it drifts westward. 


&& 


Marine/surf... 
high surf advisory is now in effect until 4 PM Monday since Saipan 
buoy indicates long-period NE swell of 7 feet persists. Marine grids 
were adjusted for initial conditions and ww3 guidance. Wind grids 
were refreshed only through 5 days with latest gfs75 since models 
show quite a bit of variability in the longer term.
