NWS Forecaster Discussion




Area forecast discussion 
National Weather Service tiyan GU 
600 PM chst Sat Jul 4 2015 


Synopsis... 
ts Chan-Hom is centered about 190 miles east of Guam near 13.2n 
and 147.6e. While Chan-Hom appeared to be getting organized at 
last this morning...its satellite signature has once again 
deteriorated this afternoon as it runs afoul of an upper-level low 
over the marianas. But satellite and radar show plenty of clouds 
and showers moving into the marianas. 


&& 


Discussion... 
with the forecast based on the 1 PM warning from jtwc...have 
issued a TY warning for Tinian and Saipan...and a ts warning for 
Rota. Chan-Hom should pass Saipan around 4 PM Sunday afternoon. 
Of course...typhoon conditions for Tinian-Saipan are predicated on 
Chan-Hom actually achieving typhoon status...and as it currently 
looks on satellite that does not seem very likely. Much depends on 
how Chan-Hom copes with the effects of the upper low overnight. In 
any case...it appears all the islands will get plenty of rain 
tonight through Sunday night...prompting the Flash Flood Watch now 
in effect. 


&& 


Eastern micronesia... 
Tropical Storm Nangka continues to move away from Majuro towards 
enewetak atoll. The Tropical Storm Warning is no longer in effect 
for wotje and utirik atolls but a typhoon watch for enewetak atoll 
and a tropical storm watch continues for kwajalein and ujae atolls. 
Expect steadily improving conditions over the next couple of days at 
Majuro as Nangka moves away. A drier pattern is expected at Majuro 
next week with a trade-wind pattern trying to establish itself 
across the region by the middle of next week. Monsoon-related 
showers and thunderstorms are prognosticated to stay primarily north of 
Kosrae for the next several days. Unsettled weather may affect 
Pohnpei Sunday night into Monday night as Nangka moves north of 
Pohnpei and causes a zone of low-level convergence to develop south 
of the tropical storm over Pohnpei. Drier conditions will resume 
Tuesday through Thursday at Pohnpei as the influence of Nangka wanes 
as it moves north of Chuuk state. 


Sea conditions remains hazardous for Pohnpei and Majuro while seas 
have fallen at Kosrae enough to drop the headline in the Kosrae 
forecast. Surf will gradually fall over the next 24 hours and should 
fall below hazardous levels at all locations by Sunday night as 
monsoon generated swell and wind waves diminish. 


&& 


Western micronesia... 
the 00z Chuuk sounding shows impressive 50 knots southwest monsoon flow 
within a layer from 2800 to 6000 feet above ground level. Satellite imagery and ascat 
data show this event continuing through the afternoon hours. 
Models do decrease winds over Chuuk tonight and tomorrow but Chuuk 
observations indicate a relatively high vertical sheared environment 
over Chuuk waters. Thus...have added a wind shear group and 
indicated higher gusts in showers in the forecast for tonight. 
Weather will improve Sunday and Sunday night but scattered showers 
are expected to return Monday and Tuesday as effects from Nangka 
become realized. 


Ridging will keep mainly dry weather over Koror through the next 
several days. Yap weather will remain under rather unsettled weather 
for the next couple of days. Drier conditions will resume Tuesday as 
Chan-Hom moves into the Philippine Sea and drags active 
monsoon weather north of Yap. 


Fresh to occasionally strong monsoon flow will keep swell and wind 
waves high enough to prolong hazardous surf at Yap and Koror through 
at least Sunday night. Seas will fall gradually over the rest of the 
weekend allowing the Small Craft Advisory headline to expire or be 
cancelled by Sunday night. 


The strong monsoon flow west of Chuuk state will promote continued 
swell generation and wind waves causing hazardous surf to continue 
along south and west facing reefs through at least Sunday night.
