Small Craft, High Surf Advisories Issued for the Marianas


Warnings will be in effect until Thursday morning

Guam – As advised by the National Weather Service, Forecast Office, Tiyan, Guam, large swells and frequent gusts associated with Tropical Storm Choi-Wan northeast of the Marianas will produce high surf and hazardous conditions to small craft over the next few days. These conditions are already occurring in Tinian and Saipan waters and could spread to Guam and Rota waters tonight or Tuesday.

A small craft advisory is in effect until 6 a.m.Thursday for Tinian and Saipan coastal waters. Combined seas of 10 feet or more are expected to produce hazardous conditions to small craft. Inexperienced mariners should avoid boating in these conditions.

A high surf advisory is in effect until 6 a.m.Thursday, for Guam, Rota, Tinian, and Saipan. Hazardous surf of 10 to 14 feet is expected along east facing reefs today. Surf along north facing reefs will build between 7 and 10 feet by Tuesday. Residents are advised to avoid venturing near exposed reefs and beaches as rip currents are life threatening. Strong waves can knock down and overwhelm strong swimmers and even small watercraft. Rip tides that accompany them may be life threatening.

The Offices of Guam Homeland Security and Civil Defense remind that all care and caution must be exercised by anyone who will be near the ocean.
