SPECIAL WEATHER STATEMENT

PMZ173-174-190800-
POHNPEI-KOSRAE-
358 AM ChST Sun Jul 19 2026

...SOUTHWEST AND SOUTHEAST SWELLS WILL CONTINUE THROUGH TONIGHT...

A tropical disturbance, Invest 90W, has opened up into an open trough
and shifted closer to just over Chuuk, with little to no convection
associated with it as a disconnected mid-level vorticity continues to
move away from the area to the northwest. In addition, the bulk of
the convective activity has shifted to a buffer circulation center
near EQ161E, taking away moisture from the area that could have
fueled the expected intense showers near Pohnpei and Kosrae. As such,
heavy rainfall and gusty winds are no longer likely to develop at
Pohnpei and Kosrae at this time, so this will be the last issuance of
this Special Weather Statement for this event.

However, a southwest to west swell generated by persistent monsoonal
winds, as well as a stronger southeast swell produced by the southern
ITCZ-like features, will remain in the area and continue to produce
surf along south and west facing reefs of Pohnpei and Kosrae the next
few days. Even so, surf is not likely to reach hazardous levels.

MAJURO-
358 AM ChST Sun Jul 19 2026

...A SOUTHEAST SWELL WILL CONTINUE THROUGH MONDAY NIGHT...

A stronger southeast swell produced by the southern ITCZ-like
features will continue to bring a chance for coastal erosion and
potentially some nuisance coastal flooding to south-facing reefs of
Majuro the next day or so. Any information to such effects should be
reported to the Majuro Weather Service Office when possible. At the
very least, mariners should continue to take this unusual wind and
swell direction into consideration when making any inter-island
travel plans.

This will be the last issuance of this Special Weather Statement for
this event.
