NWS Forecaster Discussion




Area forecast discussion 
National Weather Service tiyan GU 
836 am chst Wednesday Oct 22 2014 


Update... 
tanapag buoy and altimetry show large-northeast swell generated 
by a strong low pressure system in the North Pacific quickly 
building across the region. Tanapag buoy is indicating swell 
heights of 6 to 7 feet. Surf is likely already hazardous on north 
facing shores of Saipan and Tinian and will become hazardous on 
Rota and Guam later today. For this reason a high surf advisory 
was issued for the marianas. A secondary long-period northeast 
swell will push across the region Friday causing hazardous surf to 
continue into the weekend.

Previous discussion... /issued 528 am chst Wednesday Oct 22 2014/ 


Marianas synopsis... 
radar shows a band of widely scattered showers just to the east and 
south of the Guam marine zone. Satellite shows a few bands of clouds 
spread across the region...while scattered showers persist over far 
Northern Mariana Islands near 18n and to our south just below 10n. 
The VAD shows gradient winds east-northeast at 5 to 10 knots. Saipan buoy shows 
combined seas of 7 feet from north-northeast. 


Discussion... 
added some cloudiness to the forecast for today. A few more showers 
could also result if the band of showers to our southeast moves into 
the forecast zones. Most models still indicate that slightly deeper 
moisture will arrive by Friday or Saturday along with a weak 
troughing pattern developing across the region. 


Marine/surf... 
the tanapag/Saipan buoy indicates surf along far northern shores is 
into the 8 to 10 feet hazardous range early this morning. Ww3 model 
indicates the north swell is peaking early this morning with north 
swell subsiding slightly today...and therefore chose not to issue a 
high surf advisory at this time. It will need watched...especially 
if ritidian buoy shows larger waves arriving there. Surf for most of 
the north and northeast shores where people are active is expected 
to be in the 5 to 8 feet range. Otherwise...marine grids were adjusted 
for initial conditions and ww3 guidance. Wind grids were refreshed 
with latest gfs75 12z data. 


Eastern micronesia... 
a weak circulation just northwest of Kosrae continues to generate 
scattered showers and isolated thunderstorms. Infrared satellite shows 
this weather located between Kosrae and Pohnpei...slowing creeping 
west towards Pohnpei. Therefore...added a slight chance of 
thunderstorms there for today. Will have to watch this weather in 
case showers and thunderstorms hold together and reach Pohnpei 
this afternoon. Isolated showers and thunderstorms will persist at 
Kosrae today with drier weather tonight. Farther east...weak 
convergence has sparked a few thunderstorms near Majuro overnight 
and a surface trough east of Majuro is producing showers and 
thunderstorms near the date line. Models forecast isolated showers and 
thunderstorms to reach Majuro by Thursday...heading west reaching 
Kosrae and Pohnpei on Friday. A drier trend is expected across the 
region on Sunday. 


Western micronesia... 
dry weather and light winds will persist at Chuuk the next couple 
of days. A surface trough will approach from the east on Friday 
increasing clouds and showers across the state. Southwest winds 
today will be replaced with northeast or east trade winds by 
Saturday. 


A surface trough remains in the vicinity of Yap and Palau... 
currently stretching between the two locations. Considerable change 
was made in the short-term Koror forecast with scattered showers and 
isolated thunderstorms added this morning. Showers and thunderstorms 
at Koror will taper to isolated this afternoon. Infrared satellite 
animation shows northeast flow passing over Yap with the trough 
axis just south of where models initialize it. More clouds were 
added to Yap for today but most weather should keep to their south. 
Long-term forecast for both locations remains unchanged...but will 
need to be watched for more weather possibly along the trough in 
case it persists.

Gum watches/warnings/advisories... 
GU...high surf advisory until 4 PM chst Sunday for guz001>004. 


Marianas waters...none.
