Area Forecast Discussion
National Weather Service Tiyan GU
925 AM ChST Sun Sep 30 2018

.Marianas Synopsis...
Satellite shows Tropical Storm Kong-rey moving away from the Marianas
leaving behind mostly cloudy skies and scattered showers within the
air flowing into Kong-rey. The buoys reveal east swell of 6 to 7 feet
and west swell of 5 to 6 feet. Together these indicate combined seas
of 7 to 9 feet.

&&

.Discussion...
Weather should be drying out in the Marianas after Monday night, at
least for a few days. This will allow some of the rain fall to
percolate into the ground. The only changes needed in the grids were
to extend some of them into day 10.

&&

.Marine...
Seas and winds have been diminishing with Tropical Storm Kong-rey
moving farther away. Was able to expire the small craft advisory,
held onto the high surf advisory at this time. It is quite marginal,
but seems that it could increase in a day or two, so it seemed to
make sense to hold onto it rather than canceling and putting it up
again.

&&

.Tropical systems...
Tropical Storm Kong-rey (30W) is now intensifying in earnest.
Thankfully it is heading away from all our warning points as it does.
My seasonal tropical cyclone forecast is 38 for this year, so we may
still have 8 to go.

&&

.Eastern Micronesia...
ASCAT Analysis shows a weak surface trough over the Marshall Islands
and a weak circulation remains northeast of Majuro at about 11N178E.
Satellite shows patchy showers over the northwestern RMI and partly
cloudy skies over Chuuk, Pohnpei and Kosrae States and near Majuro.
The WW3 Wave model indicates that surf has subsided below hazardous
levels at Chuuk. Otherwise, a quiet weather pattern is expected
across the region with mainly just isolated showers and light winds
through the next several days.

&&

.Western Micronesia...
Tropical Storm Kong-rey (30W) is north-northeast of Yap and is
expected to move west-northwest and further intensify the next few
days. Fresh to strong monsoon flow will continue at Yap and Koror
while Kong-rey move across the Philippine Sea. A surface ridge of
high pressure and improving weather is expected by mid-week.

Swell from distant Typhoon Trami is merging with that from Kong-rey
and will maintain hazardous surf at Palau and Yap into next week.
Combined seas at Yap combined with the higher winds will produce
conditions hazardous for small craft thru tonight at least. Winds
will decrease at Yap by Monday, but combined seas will remain high
enough to produce the hazardous sea conditions until Tuesday.

&&

.GUM WATCHES/WARNINGS/ADVISORIES...
GU...High Rip Current Risk through Wednesday afternoon for GUZ001>004.
     High Surf Advisory until 6 PM CHST Wednesday for GUZ001>004.

Marianas Waters...None.
