Small Craft for Hazardous Seas Advisory
Statement as of 3:07 PM CST on December 26, 2014

...Small Craft Advisory for hazardous seas in effect until 9 PM CST this evening...

The National Weather Service in Corpus Christi has issued a Small Craft Advisory for hazardous seas...which is in effect until 9 PM CST this evening. This advisory is for the offshore waters Baffin Bay to Matagorda Ship Channel from 20 to 60 nm offshore.

* Winds and waves: south wind 15 to 20 knots. Seas 7 to 8 feet... with occasional seas up to 9 feet. Seas are expected to fall to less than 7 feet by late evening.

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.
