...HIGH WINDS AND HAZARDOUS SEAS DECREASE ACROSS THE FAR
NORTHERN MARIANA ISLANDS...

For Alamagan/Pagan/Agrihan

A monsoon trough continues to stretch eastward between 21N and 24N before
curving northeastward to Tropical Storm Nepartak (11W) centered far
to the north near 35N148E. Winds have subsided but remain hazardous to
small craft. Seas have also decreased but satellite altimetry indicates
seas of 10 to 12 feet remain. Models show a resurgence of activity along
the monsoon trough the second half of the week and next weekend.

Winds: Near-gale force winds of 15 to 25 mph are expected today before
tapering off by tonight. Models show winds steadily easing through
Thursday. Models show winds increasing Friday with near-gale force winds
possible by Saturday,

Seas/Surf: Large west swell and wind waves will keep seas between 10
and 12 feet today. Seas will ease tonight, falling to between 7 and
9 feet Tuesday. Hazardous surf of 8 to 10 feet is expected along south
and west facing reefs through Wednesday.

Rainfall: Rainfall of 1 to 3 inches of rainfall with locally higher
amounts is possible through Saturday.

Marine inter-island travel is discouraged today. If winds increase
this weekend as models suggest, inter-island travel may again be
discouraged.

Folks in the far northern Mariana Islands should keep up to date with the
latest statements and advisories from the National Weather Service
and your local emergency management office. Forecast products issued
by the National Weather Service are posted on the WFO Guam web page
