Coastal Waters Forecast
NATIONAL WEATHER SERVICE Honolulu HI
923 PM HST Fri Aug 17 2018

Hawaiian coastal waters within 40 nautical miles including the
Hawaiian Islands Humpback Whale National Marine Sanctuary.

PHZ100-182015-
923 PM HST Fri Aug 17 2018

.Synopsis for Hawaiian coastal waters...
A weak trough of low pressure will move through the marine area
Saturday and Saturday night. Light to moderate trade winds will
persist through Saturday, then increase to moderate and locally
strong levels Saturday night and Sunday as high pressure builds
northeast of the island chain. Moderate to strong trade winds are
then expected Sunday night through the middle of next week as
Hurricane Lane is forecast to pass by to the south of the Big
Island. It is still too early to determine exact impacts that
Hurricane Lane may have on the coastal waters, so mariners are
urged to keep up to date with the latest forecasts.
