...SURGES POSSIBLE IN NORTH FACING HARBORS ON MAUI AND BIG
ISLAND TODAY...

A north swell of 4 to 6 feet from 350 to 10 degrees at a period
of around 13 seconds may produce moderate surges in north facing
harbors today, particularly Kahului and Hilo. Mariners using these
harbors should exercise caution when mooring or launching
vessels. This swell will slowly decline into Tuesday. A swell of
similar size and period from 10 to 20 degrees is expected late
Wednesday night through Friday and may produce similar conditions
in north facing harbors.
