Area Forecast Discussion
National Weather Service Tiyan GU
317 PM ChST Thu Aug 25 2016

.Synopsis...
Other than a couple of island showers over northern Guam, it`s a
very quiet afternoon in the Marianas, with partly cloudy skies and
gentle southwest winds. Seas are down to 3 to 5 feet at the
Ritidian buoy.

&&

.Discussion...
Weather looks very dry the next week, with only isolated showers
at best and gentle southwest flow. Guam will likely see a few
island showers Friday and Saturday afternoon, along with a slight
chance of a thunderstorm, depending on available moisture. Models
show the southwest monsoon flow picking up again toward the middle
of next week, but the jury is still definitely out on that.

&&

.Marine...
Seas should remain rather low through Friday night, but a northwest
swell generated by Typhoon Lionrock about 1100 miles NW of the
Marianas will start bringing seas up again on Sunday.

&&

.Eastern Micronesia...
A trade-wind disturbance is producing showers and thunderstorms
across much of the Marshalls south of 9N. Elsewhere from Chuuk
eastward, dry conditions persist. The trade disturbance will push
to the west, bringing increased showers and isolated thunderstorms
to Kosrae Friday, Pohnpei Friday night, and Chuuk by Saturday.
After the weekend, showers will taper off, but weak trade-wind
convergence will maintain mostly cloudy skies and a small chance
of thunderstorms across the region.

&&

.Western Micronesia...
Dry weather is seen across Yap and Palau. Southwest winds persist
but have weakened some today as a low-level ridge edges farther
westward into the area. Models paint a rather dry pattern for the
next several days at both locations as winds remain generally from
the south. Weak winds the next couple of days may lead to a chance
of afternoon thunderstorms at Koror due to island heating.

Wave models continue to show a long-period north swell reaching the
area this weekend from distant Typhoon Lionrock. Surf will rise a
few feet but is expected to stay below hazardous levels.

&&

.GUM WATCHES/WARNINGS/ADVISORIES...
GU...None.
Marianas Waters...None.
