NWS Forecaster Discussion




Area forecast discussion 
National Weather Service tiyan GU 
631 PM chst Sat Aug 1 2015 


Synopsis... 
pgua Doppler weather radar shows isolated showers moving through 
the marianas waters. Satellite shows Tropical Storm Soudelor to 
the east which is gradually approaching the marianas. The VAD wind 
profile reveals deep northeast winds of 15 to 25 knots through the 
lowest 40 thousand feet of the air. 


&& 


Discussion... 
Tropical Storm Soudelor is the big forecast problem...which will 
be highlighted under the tropical systems section. Otherwise... 
the big action will be the approach of the monsoon trough. This 
has the potential to dump 6 to 10 inches of rain next week. This 
will be enough to induce periods of minor flooding during the 
heaviest showers. The clouds and showers could go on a few days 
longer than what is currently in the forecast. May have to extend 
them...perhaps more than once. 


&& 


Marine... 
buoys are showing 3 to 4 feet right now. Expect them to increase 
dramatically over the next 24 hours. Winds will also increase... 
especially north of Tropical Storm Soudelor. After Soudelor passes 
on Monday...marine conditions will gradually improve. However...it 
will be quite some time before they reach the benign levels we 
have been enjoying recently. 


&& 


Tropical systems... 
Tropical Storm Soudelor keeps getting forecast to intensify and to 
turn northwest. All last night and all day today it has remained 
a low-end tropical storm and barreled almost straight west. The 
current jtwc track has it passing between Saipan and anatahan. 
Since the strongest winds are north of the center...this would be 
ideal from the standpoint of reducing damage. However...the European model (ecmwf)- 
hires takes it over Tinian and Saipan. The gfs75 takes it over 
Tinian and Saipan. The UKMET takes it south of Tinian. Hopefully 
Soudelor will not strengthen much until it is west of the 
marianas...because it is starting to look like Tinian and Saipan 
may get the worse winds of the north side. This is why we went 
ahead and upgraded their typhoon watch to a typhoon warning. 


&& 


Eastern micronesia... 
little change to the forecast pattern and reasoning. Tropical 
Storm Soudelor is now located north of Chuuk near 14n153e and 
continues to move west. The monsoon trough extends southeastward 
from Soudelor through a weak circulation near 3n166e to end at 
eq176e. Convergent winds flowing into Soudelor are generating 
scattered showers and a few thunderstorms over Chuuk... 
Pohnpei...kwajalein and Kosrae. These showers will continue 
through the night as the storm continues to move toward the 
marianas. Active convection continues along the monsoon trough 
through Kosrae state with scattered showers and a few 
thunderstorms. The convection associated with the trough is now to 
the west of Majuro with improving conditions at Majuro the next 
few days. The circulation west of Majuro will help maintain a 
monsoon pattern over Kosrae through tonight...with a drier and 
more pleasant pattern moving in from the Marshall Islands Sunday 
evening. Drier conditions will spread westward...over Pohnpei 
Monday and over Chuuk later in the week. 


Westerly winds will cause significant swell and wind waves along the 
west coasts of micronesia. The ww3 model and altimetry data indicate 
short-period waves will be up to 5 or 6 feet across the area in the 
coming days. If the west swell builds up to around 7 feet...then 
high surf advisories may be needed. 


&& 


Western micronesia... 
Chuuk discussion is included above with the eastern micronesian 
discussion due to a similar synoptic pattern. 


The monsoon trough stretches eastward from 10n130e to about 10n140e 
then turns northeastward to Tropical Storm Soudelor. Convergence 
south of the trough is generating scattered showers and a few 
thunderstorms over the Republic of Palau this afternoon. Most of the 
convection and instability will remain to the south of Yap but the 
morning sounding indicated conditions suitable for thunderstorms so 
added isolated thunderstorms to tonights and sundays forecast. 
Expect a few thunderstorms over the state early next week. 


Seas will respond to the westerly winds with combined seas building 
across Palau and Yap this weekend. The west surf in particular could 
become hazardous by Tuesday or Wednesday.
