Special Weather Statement

COASTAL INUNDATION POSSIBLE DUE TO GIANT SURF SUNDAY INTO
MONDAY…
A large captured fetch of Gale force winds approaching within
500nm of the state will send a large northwest to north-
northwest (330 to 340 degrees) swell to the islands. Surf is
expected to rapidly build early Sunday morning, peak Sunday
evening into Sunday night at giant levels and steadily decrease
Monday into Tuesday. Due to the combination of the giant surf,
strong northerly winds, and near peak monthly high tides, overwash
of low-lying coastal areas and roadways is likely Sunday through
Monday, with the most vulnerable time frame around the high tide
cycle Sunday night. Also, significant beach erosion can be
expected and strong harbor surges may cause damage to boats and
infrastructure along north and west facing coastlines and harbors.
