NWS Forecaster Discussion




Area forecast discussion 
National Weather Service tiyan GU 
358 PM chst Monday Oct 20 2014 


Marianas synopsis... 
pgua WSR-88D shows almost no showers in the marianas waters. It also 
shows a line of showers and thunderstorms to the south of Guam 
waters. The VAD wind profile reveals northeast winds of 10 to 15 
knots through the lowest 6 thousand feet of the air. 


&& 


Discussion... 
weak chaotic flow pattern remains in place with many small troughs 
and ridges. Winds are expected to gradually become lighter through 
the forecast period. Main event will be swell from a storm north of 
wake which has moved very little over the past 4 days. This means 
the winds have great persistence and a fairly long fetch of 1200 
nautical miles. The limiting factor will be the wind speed of 30 
knots. This will maintain elevated surf for the rest of the week 
once it arrives around Wednesday. Inherited grids handled this well 
so no changes were needed. 


&& 


Eastern micronesia... 
a circulation could be found northeast of Kosrae this afternoon. 
Models keep the circulation weak and agree on pushing this feature 
south and eventually wash it out by Wednesday. Light and variable 
winds to light westerlies can be expected across Pohnpei and Kosrae 
through middle week. East trade-winds will return to these two areas by 
Thursday. 


A surface trough...now east of the dateline...will push west. The 
trough will remain weak but will bring mostly cloudy skies to 
Pohnpei and Kosrae the second half of the week. This trough will 
bring an increased chance of showers to Majuro Wednesday and 
Thursday. Convergence in the wake of the trough will keep skies 
mostly cloudy at Majuro Friday and Saturday. 
&& 


Western micronesia... 
a surface trough stretched across western micronesia north of 10n 
this afternoon. This trough will remain in the same general location 
through at least Wednesday. This afternoon north winds prevailed at 
Palau and Yap with west winds at Chuuk. Little will change trough 
Wednesday. The trough will decay and east trade-winds will return to 
western micronesia the second half of the week. Models keep things 
tranquil and only isolated showers are expected through the 
forecast. 


&& 


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