Area forecast discussion 
National Weather Service tiyan GU 
631 am chst Thursday Jul 31 2014 


Marianas synopsis... 
infrared satellite imagery shows that Tropical Storm Halong...centered 
about 170 miles west-northwest of Guam near 14.5n 143e...is still struggling 
with strong upper-level winds and dry air...and has weakened 
slightly the last few hours as it moves away from the marianas. 
Locally...winds have dropped to 15-20 knots and seas are down to 9 feet 
at the ritidian buoy and still falling. Radar shows multiple lines 
of showers and thunderstorms being kicked eastward out of Halong 
and moving across Guam and Rota. 


&& 


Discussion... 
after originally going with isolated showers and thunderstorms 
today...have already updated for scattered showers for Guam and 
Rota...as Halong has been spitting out lines of showers that have 
consolidated into quite a wide band of scattered showers and 
thunderstorms. Thus...have inserted scattered showers into the 
forecast this morning for Guam and Rota. Otherwise...the next few 
days should see improving conditions with isolated showers and 
moderate winds. Little change made to the forecast after 
today...and we should see a respite of a week or more of fairly 
quiet weather. 


&& 


Marine... 
based on latest buoys...took a couple of feet off the total seas 
the next two days...and with ritidian down to 9 feet...Small Craft 
Advisory may come down a little early. High surf is still good 
through at least Sun morning...and maybe a bit longer. 


&& 


Eastern micronesia... 
a tropical disturbance centered just east of Pohnpei is maintaining 
scattered showers and isolated thunderstorms at Pohnpei this morning. 
Isolated showers are seen farther east across Kosrae state while 
drier weather is present across the Marshall Islands. The tropical 
disturbance will slowly head west the next couple days. Convergence 
east of the disturbance will keep isolated showers and thunderstorms 
in place at Kosrae and Pohnpei at least through Friday night. Drier 
weather will build westward from the Marshall Islands on Saturday. 
At Majuro...fair weather is expected the next few days. However...infrared 
satellite imagery shows low-level moisture and spotty convection 
associated with a surface trough east of Majuro along the date line. 
Models do very little with this feature...keeping most of the 
weather over the northern Marshall Islands as it moves west. For 
now...will maintain mostly cloudy skies for Friday and Friday 
night. 


&& 


Western micronesia... 
fair weather remains in place this morning at Chuuk but a tropical 
disturbance near Pohnpei will bring isolated showers and 
thunderstorms to the state tonight. The disturbance will slowly pass 
over Chuuk before turning towards the northwest Friday night and 
Saturday. Weak ridging will promote drier weather through the 
weekend. 


Again...only few changes were made to the Yap and Koror forecasts. 
Tropical Storm Halong centered about 490 miles northeast of Yap at 
14n143e continues to move west this morning. Ridging south of Halong 
will keep dry and pleasant weather in place at Koror and Yap today. 
Middle and upper level clouds near the periphery of Halong will spread 
over Yap today. Models indicate isolated showers and thunderstorms 
are possible at Yap tonight through Saturday as Halong continues 
west. Halong is prognosticated to turn northwest by Saturday while 
gradually strengthening. This will increase the monsoon flow across 
Yap and Koror over the weekend but drier weather is expected to 
prevail then.

Gum watches/warnings/advisories... 
GU...high surf advisory until 6 am chst Sunday for guz001>004. 


Marianas waters...Small Craft Advisory until 10 am chst Friday for 
pmz151>154.
