NWS Forecaster Discussion

Area forecast discussion 
National Weather Service tiyan GU 
420 PM chst Sat Feb 13 2016 

high pressure is centered to the north of the marianas and a 
shear line is located just south of Guam this afternoon. Dry 
weather is expected through much of the coming week. 


high pressure centered to the north will move eastward. The pressure 
gradient between the high and the shear line will keep winds up 
tonight. As the high pressure moves farther east the gradient will 
lessen and so will the winds. Winds on Sunday are predicted to be 
15 to 20 miles per hour. The proximate of the the shear line to the south 
will keep skies mostly cloudy tonight. As the shear line 
deteriorates so will the clouds with partly cloudy skies expected 
Sunday. Deep layer moisture will be at a minimum through the week 
so there will only be a slight chance of showers through at least 
Tuesday night. A trade-wind surge will increase winds and the 
chance of showers by the end of the week. 


ipan and tanapag buoy data show combined seas around 10 to 11 feet this 
afternoon. East trade-wind swell will persist through the forecast. 
The east swell will produce surf of 8 to 10 feet on east facing reefs 
through at least Monday. A north swell of five feet will combine with 
the east swell to produce hazardous surf on north facing reefs through 
Monday. Winds will be high enough to br hazardous for small craft 
tonight and seas will remain hazardous through Monday. 


Eastern micronesia... 
a surface trough is producing scattered showers south of Pohnpei 
this afternoon...but it is expected to move south and weaken. The 
only other significant feature is a trade-wind disturbance moving 
across the date line toward Majuro. Isolated thunderstorms are 
likely at Majuro tonight as the disturbance nears...then scattered 
showers and isolated thunder are expected for Sunday and Sunday 
night. As the disturbance continues westward...Kosrae will likely see 
an extended period of unsettled weather with isolated showers and 
thunderstorms Monday into Thursday...with scattered showers a 
possibility at times during that period. Only isolated showers are 
forecast for Pohnpei...but the disturbance could bring scattered 
showers later in the week if it lasts that long. 
Meanwhile...strong trades will persist the next 2 to 3 days as 
strong high pressure moves by to the north. Also...high surf will 
persist at Pohnpei and Kosrae a few more days...and surf should 
become hazardous at Majuro on Sunday. 


Western micronesia... 
with the shear line remaining up north...fairly dry weather is 
expected across western micronesia. Winds and seas are subsiding now 
at Koror and should subside on Sunday for Yap...but hazardous winds 
and seas are expected to persist through Monday night at Chuuk. At 
the same time...high surf should end on Sunday for Koror and 
Yap...but will linger into at least Tuesday at Chuuk. 
Meanwhile...only isolated showers are expected the next few days.
