Small craft and high surf advisories in effect
Based on information received from the National Weather Service in Tiyan, Guam, and compiled at the CNMI Emergency Operations Center State Warning Point, a large northwest swell is being created by northwest winds behind a cold front moving out of Japan. Persistent strong northeast winds are also creating a large northeast swell. These swells will maintain hazardous surf for the Marianas the next few days.
A high surf advisory remains in effect until 6pm Thursday. Surf is currently hazardous at 8 to 10 feet on north and west facing reefs. The surf is expected to peak today, Wednesday, at 10 to 12 feet. Surf will begin to subside Thursday and could fall below hazardous levels Thursday night.
Increasing northeast swell and wind waves will result in hazardous surf of 9 to 12 feet along east facing reefs. Surf will remain at these levels before beginning to subside tonight.
Minor beach erosion and strong rip currents are possible at beaches along coastlines facing north and west. Ritidian and Tarague beaches in Guam are likely very susceptible. Additionally, Portuguese man-of-war was recently reported at Asan Beach in Guam.
A small craft advisory remains in effect until 6pm Thursday. Fresh to strong winds of 20 to 25 knots with near gale gusts are expected through Thursday. Combined seas of 9 to 12 feet will likely remain hazardous through Thursday.
Inexperienced mariners, especially those operating smaller vessels, should avoid sailing in these conditions. Avoid venturing near reefs along exposed beaches, especially those facing north, east, and west, as rip currents will be life threatening. (EOC)
