National Weather Service Tiyan GU

.Marianas Synopsis...
Satellite shows a band of light trade-wind showers crossing Guam this
afternoon, but otherwise only isolated showers are present across the
Marianas. Combined seas range from 4 to 6 feet at the buoys.

&&

.Discussion...
Our dry-season regime remains firmly in place with mainly moderate
trades and isolated showers throughout the seven-day forecast period.
Isolated thunderstorms are still in the forecast for Tuesday night
and Wednesday, but support for that is weaker in today`s model runs.


&&

.Marine...
East-northeast swell will peak Sunday and Sunday night, with 9-foot
surf expected on east facing reefs. Combined seas will vary over a
small range the next few days, from 5-7 ft tonight to 4-6 ft Sunday
night, then back to 5-7 feet later next week.

&&

.Eastern Micronesia...
Dry weather is seen across the region with just some trade-wind
showers across the Marshalls and northeast of Kosrae. A weak trough
is expected to develop near Kosrae over the next couple of days which
will cause the ITCZ to become more active early in the week. Showers
will increase at Majuro and Kosrae Monday and at Pohnpei by Tuesday.
Weaker and drier trades will return around midweek.

&&

.Western Micronesia...
A weak circulation remains well southeast of Koror near 2N142E with
a surface trough extending west-northwest toward the Philippines.
Showers and thunderstorms remain south of 6N while Koror, Yap, and
Chuuk all remain quite dry. Showers will shift northward closer to
Koror the next few days, bringing more clouds to the area, but
scattered showers are expected to stay just south for now. Yap, will
also stay quite dry, with skies becoming partly cloudy at times. A
trade-wind trough will bring increasing showers and some
thunderstorms to Chuuk early in the week but drier trades are
expected to return around midweek.
