NWS Forecaster Discussion

Area forecast discussion 
National Weather Service tiyan GU 
708 am chst Monday Dec 22 2014 

Marianas synopsis...east trade-winds and a few showers prevailed 
across the marianas this morning. 


little change made to forecast. East trade-winds of 10 to 20 miles per hour 
will prevail across the marianas today. Winds are expected to 
increase Tuesday as an area of high pressure moves off of Asia. 
Models depict a few trade-wind disturbances passing across the 
local area through the week. None of the disturbances are 
predicted to be associated with deep layer moisture. Expect on 
and off periods of clouds and showers during the week. 


an east trade-wind swell will persist through the forecast and a 
north swell will continue through Friday. Buoy data indicate seas 
near Guam and Saipan 9 to 10 feet. Satellite altimetry also shows 
seas between 10 to 12 feet over the marianas. Seas are high 
enough to keep the Small Craft Advisory in effect today. Models 
keep the seas within small craft criteria through at least Friday. 
Winds will increase and will also be within small levels from 
Tuesday through Wednesday night. 


Eastern micronesia... 
scattered showers and isolated thunderstorms are seen south of 
Chuuk...Pohnpei and Kosrae along the northern edge of a surface 
trough. Additional showers are present near Majuro along the 
leading edge of a trade-wind surge. A slow west-moving TUTT cell 
near the Marshalls is aiding deep convection and will draw 
convection westward today. Showers and thunderstorms will 
gradually pass to the west of Majuro reaching Pohnpei and Kosrae 
between Tuesday and Wednesday. 

The primary forecast concern for the region is the building seas 
in response to strong trade-winds. Latest ascat data show winds 
around 25 knots near the Marshalls with 30 knots winds seen farther to 
the north. Choppy seas will persist across most of the region 
from Chuuk to Majuro for the next several days. Have issued high 
surf advisories for Chuuk...Pohnpei and Majuro as well as 
continued the advisory at Kosrae. Surf will build an additional 1 
to 2 feet at all 4 locations between tonight and Tuesday. 
Globalwave and wavewatch models both indicate surf could reach 
warning levels of at least 15 feet at Majuro tonight or Tuesday. 
1 to 2 feet of inundation is possible across the Marshalls near 
times of high tides. 


Western micronesia... 
Chuuk discussion is included in eastern micronesia due to similar 
weather and marine conditions. 

Satellite imagery shows showers and thunderstorms moving farther 
away to the northwest as a surface trough crosses west of 130e. 
This will allow for drier conditions to persist for the next 
several days. GFS and European model (ecmwf) both show a disturbance approaching 
from Chuuk state later in the week that will bring another round 
of showers and thunderstorms to the area around Thursday and 

Combined seas will build 1 to 2 feet around midweek as both trade 
winds increase and a long-period north swell reach the area. 


Gum watches/warnings/advisories... 
Marianas waters...Small Craft Advisory until 6 am chst Friday for pmz151>154.
