The CNMI Homeland Security and Emergency Management warned yesterday that a small craft advisory for hazardous seas remains in effect until 6pm today, Thursday.
An east to northeast swell generated by Supertyphoon Lekima will result in combined seas building to 10 to 12 feet in Tinian and Saipan waters, producing hazardous conditions for operators of small craft. Seas are expected to fall below 10 feet Thursday night.
A high surf advisory is also in effect until 3pm today.
Hazardous surf of 7 to 9 feet is expected to persist along north facing reefs through at least Thursday afternoon as a reinforcing shot of north swell from Supertyphoon Lekima will maintain hazardous surf along north facing reefs for a little longer.
Mariners should avoid shoaling areas where long period swell can sharpen into large breaking waves. 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.
The public is advised to avoid venturing near exposed reefs and beaches, especially those along west and north facing reefs as rip currents will be life threatening. Inexperienced mariners, especially those operating smaller vessels, should avoid boating in these conditions. If travel by boat is necessary, exercise caution, especially near reef lines and when entering or leaving harbors and inlets. (PR)
