Special Weather Statement
Urgency:
Expected
Effective:
July 18, 2026 - 10:58am
Expires:
July 19, 2026 - 1:00am
Description:
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.
