The biggest in a series of extra large northwest swells will
reach Kauai during the predawn hours, then rapidly spread down the
island chain on Sunday. The swell is expected to produce large
hazardous breaking waves at channel entrances and may lead to
surges in harbors facing north and west on Kauai, Oahu, and Maui.
Mariners using these harbors should exercise caution when
entering or leaving port and when mooring or launching vessels.
