Public warned: Seas will still be dangerous

Posted on Oct 10 2019

A high surf advisory is in effect until 10am tomorrow, Friday.

A high surf warning indicates that dangerous battering waves will pound the shoreline. This will result in life-threatening conditions and the potential for coastal inundation and erosion.

Hazardous seas warning was also in effect yesterday and a small craft advisory is in effect until Friday morning.

Based on information received from the National Weather Service in Tiyan, Guam, and compiled at the CNMI Emergency Operations Center State Warning Point, Super Typhoon Hagibis continue to generate dangerous seas and surf in the CNMI.

Large west swells from Hagibis continues to produce dangerous surf along north and west facing reefs of Tinian and Saipan. Hazardous surf is expected in the next couple of days along north, west, and south facing reefs of the Marianas.

Along north facing reefs, surf will be hazardous at 9 to 11 feet today, Thursday.

Along west facing reefs, surf will fall to 10 to 12 feet today.

Along south facing reefs, surf will fall below hazardous levels today.

Southwest winds will gradually subside to between 15 and 20 knots by today, while combined seas of 13 to 16 feet will slowly subside the next few days. Seas may fall below hazardous levels of 10 feet Friday.

Hazardous sea conditions are still occurring, though. Recreational boaters should remain in port or take shelter until waves subside. Commercial vessels should prepare for rough seas and consider remaining in port or taking shelter in port until hazardous seas subside.

Inexperienced mariners, especially those operating smaller vessels, are advised to avoid sailing in these conditions. Do not venture out along north, west, or south facing reefs and beaches. Large breaking waves can knock you down and cause serious injuries. Strong rip currents will be life threatening. (PR)
