NWS Forecaster Discussion




Area forecast discussion...updated 
National Weather Service tiyan GU 
631 PM chst Sat Feb 6 2016 


Synopsis... 
east to southeast winds and a few showers prevail across the 
marianas this afternoon. 


&& 


Discussion... 
no big changes made to the forecast. High pressure centered to 
the northeast of the marianas will continue to move further away 
from the area. Fresh to strong trade winds over the area this 
afternoon will quickly subside tonight as the pressure gradient 
decreases. This lull will be temporary as another high pressure 
area will build out into the northwest Pacific through the coming 
week. East trade winds will start building by Monday and 
gradually increase to 20 to 25 miles per hour by mid-week. The pressure 
gradient will increase the second half of the week which will 
correspond to a further increase in winds. 


Weather satellite imagery does show a few patches of clouds and 
showers to the east of the marianas. While brief periods of clouds 
and showers are possible through the week...the prevailing 
conditions will be partly cloudy with isolated showers. A shear 
line may push down to the local area by next weekend and bring a 
higher chance for clouds and showers. 


&& 


Marine... 
scatterometer data and local observations showed winds this 
afternoon were high enough to produce conditions hazardous to 
small craft. Models show a rapid decrease in winds so the advisory 
will only be out until sunset. 


Ipan and tanapag buoy data show combined seas around 5 to 7 feet 
this afternoon. East trade-wind swell will persist through the 
forecast. The east swell will produce surf of 6 to 8 feet and 
generate a moderate rip current risk on east facing reefs through 
the first half of next week. A north swell has entered the area 
but will remain relatively small. Seas will increase the second 
half of the week as winds increase. 


&& 


Updated to add micronesia discussions 


Eastern micronesia... 
a dome of high pressure north of Wake Island near 31n167e is 
channeling fresh to strong trade winds toward the region. The 
leading edge of this surge is just east of Chuuk this evening. 
Several weak disturbances embedded within the trades could trigger 
a few light showers across all the locations from time to time. 
Otherwise...a general dry trade pattern will continue most of next 
week. 


The focus is on the large trade-wind waves and swell moving across 
the area over the next few days. They are already producing 
hazardous surf across the Marshall Islands and Kosrae state...and 
might spread it to Pohnpei and Chuuk states this weekend. 
Combining with a King tide cycle of higher than 5 feet near 
Majuro...coastal inundation will be possible especially during 
high tides along east facing shores by Sunday afternoon. Seas will 
also be hazardous for small craft operation for the next few days. 


&& 


Western micronesia... 
reasoning for the Chuuk forecast is included in the eastern 
micronesia section due to a similar trend. 


Two distinct surface troughs are moving across the Republic of 
Palau and Yap state. They will continue to create passing showers 
for both places this evening. The one near Yap has produced a 
wetting rain of 0.20 inches late this afternoon. This can provide 
temporary relief on dry fuels which can contribute to wild fire. 
However...this means very little in terms of replenishing the 
water supply. A very dry regime is still expected for much of this 
coming week. Residents are advised to continue conservation on 
water. 


&& 


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