Small Craft for Hazardous Seas Advisory
Expires 7:00 AM EST on January 19, 2019

Statement as of 4:56 am PST on January 18, 2019


... Small Craft Advisory for hazardous seas remains in effect
until 4 am PST Saturday...

* waves/seas... combined seas 12 to 16 feet in the outer coastal
waters and 8 to 12 feet in the inner coastal waters. The
predominant swell will be from 280 degrees with a period of
16-19 seconds. Combined seas will diminish to 8 to 11 feet in
the outer coastal waters and 6 to 8 feet in the inner coastal
waters by tonight.

Precautionary/preparedness actions...

A Small Craft Advisory for hazardous seas means that waves are
expected to be hazardous to small craft. Mariners should avoid
shoaling areas. Long period swell can sharpen into large breaking
waves in shoaling areas. It is not unusual for waves to break
much farther from shoaling areas than is normally experienced.
Remember... breaking waves can easily capsize even larger vessels.
