NWS Forecaster Discussion




Area forecast discussion 
National Weather Service tiyan GU 
515 PM chst Friday Dec 19 2014 


Marianas synopsis... 
a robust shear line stretches southwestward over the far northern 
marianas. A cluster of showers is passing through Guam waters but 
the heaviest convection remains south of Guam waters. Radar wind 
profile shows 30 to 35 knots northeast winds from 2000 to 5000 feet 
while surface observations show 20 knots with gusts to 30 knots across 
the region. 


&& 


Discussion... 
fresh to strong northeast winds will prevail through Saturday 
before diminishing somewhat late Saturday. Mainly dry conditions 
are expected for the next several days as the shear line stalls 
across the far northern marianas over the weekend. Winds will 
decrease a bit Saturday night but will remain fresh through the 
next few days. A secondary trade-wind surge will increase winds 
once again by the middle of next week but no major weather 
systems are expected to affect the marianas. 


&& 


Marine... 
ritidian buoy shows seas have risen steadily today to around 11 
feet. A Small Craft Advisory remains in effect at least through 
Wednesday morning. Most of the wave energy is wind waves but persistent 
fresh to strong trade winds will continue to build a significant 
east-northeast swell over the next 36 hours. This will bring surf on east 
facing shores very close to hazardous levels by Saturday morning. 
A high surf advisory issuance will likely be needed overnight for 
east facing reefs. 


&& 


Aviation... 
wind shear could be an issue overnight on Guam if significant 
decoupling of the planetary boundary layer occurs. Winds at the surface would have to 
decrease to between 10 and 15 knots for wind shear to become an 
issue. 


&& 


Eastern micronesia... 
satellite shows showers associated with a trade-wind disturbance 
moving westward across the date line toward Majuro and the tarawa 
and butaritari areas. A weak circulation near 2n169e is causing 
showers in a small area southeast of Kosrae. Models indicate the 
circulation and the disturbance will move westward in the coming 
days with showers focused mainly between 3n to 7n. Moderate to 
fresh trade winds are developing for eastern micronesia and 
relatively wet weather is expected to spread westward... 
especially toward Kosrae. The heavier shower activity could 
remain south of Majuro and Pohnpei if model solutions are 
correct. 


Relatively dry weather is expected at Chuuk next couple days... 
then some cloudiness and showers could spread toward Chuuk from 
eastern micronesia early next week. 


Northwest swell produced by strong winds over the northwest 
Pacific along with large trade-wind swell and wind waves will 
cause sea conditions to rise from Chuuk state eastward to the 
Marshall Islands over the next few days. Conditions could 
possibly become hazardous for small craft by Sunday or Monday. 
Trade-wind waves may also cause hazardous surf for Kosrae and the 
Marshalls as well. And...with Spring high tide cycle starting 
Monday...coastal inundations are likely on Majuro and nearby 
atolls. 


&& 


Western micronesia... 
reasoning for the Chuuk forecast is included under the eastern 
micronesia section above due to a similar trade-wind pattern. 


Models indicate a period of moderate to fresh trade winds can be 
expected across western micronesia. Weather there will be 
relatively unsettled even through the longer term. Satellite 
shows scattered showers and a few thunderstorms south of Guam 
between 10n and 12n that are moving westward. The showers could 
affect Yap the next day or two. Satellite also shows patchy 
clouds and a few showers just west and southeast of Koror. Models 
indicate that a little drier weather will develop for Koror this 
weekend...but surging trades from eastern micronesia could 
increase the chance of showers for both Yap and Koror next week. 


Hazardous surf will persist across the Republic of Palau and Yap 
state through Saturday evening as north swells produced by gale 
force winds over the northwest Pacific continue to affect the region. As 
northwest swell combine with trade-wind swells and wind waves...seas 
will also remain hazardous for small craft until Sunday. 


&& 


Gum watches/warnings/advisories... 
GU...none. 
Marianas waters...Small Craft Advisory until 6 am chst Wednesday 
for pmz151>154.
