NWS Forecaster Discussion




Area forecast discussion 
National Weather Service tiyan GU 
535 PM chst Friday Jul 25 2014 


Marianas synopsis... 
animated visible satellite imagery shows the monsoon trough is 
approaching from the south. The trough is currently positioned 
south of Guam near 10n. A trade-wind disturbance is pushing 
through the forecast zones at present. Another upstream trade- 
wind disturbance is positioned roughly halfway between Wake 
Island and the marianas. 


&& 


Discussion... 
forecast still assumes passage of the monsoon trough through the 
forecast zones during the next day or so. Added scattered showers 
and isolated thunderstorms this evening to factor in the passage 
of the first trade-wind disturbance. Second trade-wind 
disturbance should track toward the northwest and miss the 
forecast domain. Model guidance suggests monsoonal convection 
will develop during the favored overnight hours on Saturday night 
and Sunday night...then continue in earnest on Monday and Monday 
night as low-level convergence improves in strengthening monsoonal 
low-level flow. As 96w lifts northwestward...peripheral ridge to 
the southeast should build overhead and promote improving weather 
during the second half of next week. Will ignore system the GFS 
brings over the forecast zones during the middle of next 
week...unless this system begins to develop near Pohnpei early 
next week as prognosticated. 


&& 


Marine... 
for the time being...expect moderate rip current risk to continue 
through Saturday...then swell generated by the southwest monsoon 
on the southeast side of 96w will cause surf and seas to build. 
Trimmed back southwest swell heights tonight through Saturday 
based on marianas buoy readings. Added southwest swell from the 
wave watch model Saturday night through Tuesday night from 
building surge arriving from the Philippine Sea. Did shave a few 
feet from the southwest swell heights during this time frame for 
now...but if 96w does intensify significantly...southwest swell 
could become high enough to generate hazardous surf as early as 
Sunday night. Will ignore swell generated to the east of Guam 
during the second half of next week by a system the GFS is 
developing near Pohnpei on Sunday and Monday. 


&& 


Eastern micronesia... 
a Special Weather Statement was issued for all of micronesia and 
heavy weather continues to develop across eastern micronesia. 
Ascat analysis shows the monsoon trough runs eastward along 8n-9n 
to the north of Pohnpei and Kosrae into the northwestern rmi. 
Also...a weak circulation is centered near 3n168e. Satellite 
shows heavy convection has been developing all around both the 
monsoon trough and the circulation...with numerous showers and a 
few thunderstorms developing upstream from Majuro. Showery and 
inclement weather will continue over eastern micronesia for the 
next couple of days at least. Models indicate the monsoon trough 
will gradually lift farther north in the coming days and weather 
should gradually improve for these forecast points by next week. 


Hazardous surf advisory remains in effect for Pohnpei and Kosrae 
and those conditions may be slower to improve than previously 
thought. The situation will need to be watched closely. 


&& 


Western micronesia... 
a Special Weather Statement was issued for all of micronesia and 
jtwc invest area 96w will need to be watched closely. Ascat 
analysis indicates a weak low-level circulation associated with 
96w is very close to Koror. The monsoon trough extends eastward 
from 96w across northern Chuuk state. The development of 96w is 
the main forecast problem for Koror and Yap. Models indicate it 
will intensify as it lifts northward along with the monsoon 
trough. Models indicate that moderate to strong southwest winds 
and showery weather will continue on Koror and Yap through the 
longer term. For Chuuk...monsoon-type weather will continue and 
conditions will be changeable...depending on how the active 
weather over eastern micronesia develops and moves in the coming 
days. 


Hazardous surf advisory was issued for Koror...Yap...and Chuuk in 
anticipation of moderate to strong west to southwest monsoonal 
flow persisting across western micronesia. Conditions could 
deteriorate even more if invest 96w quickly becomes more intense.
