...HIGH SURF ADVISORY IN EFFECT UNTIL 6 PM HST FRIDAY FOR NORTH
AND WEST FACING SHORES OF NIIHAU KAUAI AND OAHU...

.Two significant northwest swells are expected to impact the
state over the next several days, originating from a broad and
complex low that evolved over the far northwest Pacific over the
past few days. The first moderate to large long period northwest
swell will build down the island chain through the day today,
while an overlapping stronger long period northwest swell will
build in on Friday. This swell energy will also produce High Surf
Advisory (HSA) conditions today for north and west facing shores of
Niihau, Kauai and Oahu. This will be a long duration event, with
a peak centered around the Friday through Saturday time period.
The rising swell will swiftly exceed warning levels from late
Friday through Saturday for the same northwest islands, expect the
HSA to expand in coverage to the islands of Molokai, Maui and
west facing shores of the Big Island by Friday.
