A large north swell generated by strong winds from a winter storm well east of Japan will maintain hazardous surf across the Mariana Islands until this afternoon, Tuesday, according to the CNMI Homeland Security and Emergency Management, citing data from the National Weather Service in Tiyan, Guam.
A high surf advisory remains in effect until 6pm today. Hazardous surf of 8 to 10 feet on north facing reefs will gradually drop to between 7 and 9 feet this morning. Surf will fall below hazardous levels this evening. Hazardous surf will produce life-threatening rip currents along north facing reefs.
A small craft advisory remains in effect until 6pm today. Northeast winds between 15 and 25 knots will continue through this afternoon. The combination of a large north swell and wind waves will produce seas of 8 to 10 feet through this afternoon.
The public, 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. Do not venture near exposed reefs and beaches, especially those along north facing reefs as rip currents will be life threatening. (HSEM)
