Area Forecast Discussion
National Weather Service Tiyan GU
528 PM ChST Mon May 28 2018

.Marianas Synopsis...
Conditions remain quiet across the Marianas, with moderate trades,
isolated showers, and combined seas around 4 feet. Some thin haze
derived from Mt. Kilauea in Hawaii is having little effect on
visibility, and presents no hazards to aviation or marine activities.

&&

.Discussion...
Wind and wave forecasts are left unchanged, as moderate trades and
slowly increasing seas are still expected. Models have delayed the
arrival of deeper moisture until Friday, so have pushed back any
thunderstorms until then, and have also extended them into Monday
of next week. Scattered showers are possible this coming weekend
into the following Monday, but it is too early to forecast that with
any confidence.

&&

.Eastern Micronesia...
An active weather pattern persists across the region with trade-wind
convergence continuing to produce showers and thunderstorms.
Convection will gradually lift northward the next few days, allowing
for some drying before showers redevelop to the south next weekend.
The region could still see some volcanic haze the next few days, but
showers in the area will help to reduce the amount of haze. Central
Pacific wind patterns will change slightly around midweek,
redirecting the haze farther to the north.

&&

.Western Micronesia...
Wet weather will persist at Chuuk as trade-wind convergence remains
focused between 6N and 9N. After a trough passes through around
Wednesday, showers will diminish and lift northward. Slightly drier
weather is expected in the latter half of the week. Farther west, a
disturbance will maintain showers and thunderstorms at Koror through
tonight. Yap will gradually clear out overnight with clouds
diminishing this evening. A weak circulation expected to develop
nearby late in the week will keep winds at Koror and Yap weak and
variable in direction while promoting an unstable weather pattern.

&&

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