NWS Forecaster Discussion




Area forecast discussion 
National Weather Service tiyan GU 
436 PM chst sun Mar 29 2015 


Synopsis... 
pgua WSR-88D shows almost no showers in the marianas waters. The 
VAD wind profile reveals east-northeast winds of 12 to 25 knots 
through the lowest 5 thousand feet of the air. 


&& 


Discussion... 
marianas are within the subsident mote around distant Typhoon 
Maysak tonight. The outermost rainband on the north side will 
approach the marianas Monday night...and could continue through 
Tuesday night. After this...the marianas will fall back into a dry 
season trade-wind regime. There is ongoing convection in the 
Marshall Islands which the gfs40 is trying to develop into another 
tropical cyclone. If the European model (ecmwf)-hires jumps on the bandwagon... 
will have to give it more credence at that time. It is still at 
least a week away no matter what. 


&& 


Marine... 
fresh to strong trade winds north of Typhoon Maysak will continue 
to generate hazardous conditions for small craft. The ipan buoy 
shows waves are increasing and are now at 8 to 10 feet. They should 
reach 10 to 12 feet Monday...then start diminishing Tuesday. 


&& 


Tropical systems... 
Typhoon Maysak went over Chuuk lagoon this morning...and will soon 
pass well south of the marianas. Maysak is expected to pass close 
to Yap late Tuesday night or early Wednesday morning. Maysak has 
sustained winds of at least 70 knots now and is expected to 
intensify further. Maysak could become a major typhoon Monday 
night or Tuesday. 


&& 


Eastern micronesia... 
satellite and ascat wind analysis show a disturbance with a large 
area of heavy showers moving slowly across the Marshall Islands. 
Lingering showers associated with Typhoon Maysak continue to train 
across Pohnpei state...but Maysak is moving slowly westward away 
from Chuuk and weather conditions should gradually improve Monday 
across Pohnpei state. Just patchy clouds and isolated showers remain 
across Kosrae state this afternoon. Models indicate the disturbance 
over the rmi will move slowly westward and could further develop 
into a circulation during the coming days. GFS model indicates a 
pattern of low-level convergence will cause showers to persist 
across eastern micronesia mainly along about 5n for most of this 
week. 


Building trade-wind waves and swell will cause hazardous sea 
conditions for Majuro during the next few days. 


&& 


Western micronesia... 
Chuuk...typhoon warning remains in effect. Typhoon Maysak is moving 
slowly westward away from Chuuk and weather conditions will very 
slowly improve. Typhoon force winds likely caused significant damage 
for Chuuk state. Occasional showers with gusty winds can be expected 
during the next couple of days. The weather should improve by middle- 
week...but the disturbance over eastern micronesia today could move 
to the Chuuk area by Friday and forecasts for later this week will 
be subject to significant changes. 




Yap and Koror...a typhoon watch remains in effect for Yap island. 
Typhoon Maysak is moving westward away from Chuuk this evening and 
model consensus indicates it will track directly toward the Yap area 
by Tuesday. Exact weather conditions for Yap and Koror will depend 
on the precise track of Maysak...but damaging winds are likely for 
Yap within the time frame of Tuesday through wedneday. Maysak will 
need to be monitored very closely. Meanwhile...moderate to fresh 
trade winds will continue tonight and Monday over far western 
micronesia. 


High surf advisory is no longer in effect for Yap and Koror...but 
surf will likely build to dangerous levels...especially at Yap... 
with the approach of Typhoon Maysak Monday night or Tuesday. 


&& 


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