Rough weather seen until the weekend
A northwest to northeast swell will produce hazardous surf across the Marianas and a high surf advisory remains in effect through Friday night.
Also, a small craft advisory remains in effect through Saturday night.
Based on the information received from the National Weather Service in Tiyan, Guam, and compiled at the CNMI Emergency Operations Center State Warning Point, a northwest swell will combine with building northeast swell to produce hazardous surf and a high risk of rip currents along north and east facing reefs the next few days.
There is a high risk of rip currents through Friday night along north facing reefs. Expect hazardous surf of 8 to 10 feet today, Wednesday, falling to hazardous at 7 to 9 feet Wednesday night and Thursday.
Surf may fall below hazardous levels Thursday night or Friday. The risk of rip currents will be high. Along east facing reefs, the risk of rip currents will be high for the next several days. Surf will likely become hazardous at 12 feet or more by Thursday.
Northeast winds of 20 to 25 knots will rise to 25 to 30 knots today until tonight. Winds will remain fresh to strong through the week.
Combined seas of 9 to 10 feet will build to 11 to 13 feet by Thursday and 12 to 14 feet on Friday. Highest seas will be east of the islands.
The public is advised to avoid venturing out near reef lines along north and east facing reefs. If you become caught in a rip current, remain calm. Stay afloat while waiting for help. If you have to swim out of a rip current, swim parallel to shore, then back toward the beach when possible. Do not attempt to swim directly against a rip current as you will tire quickly.
These winds and seas will be hazardous to operators of small craft. Inexperienced mariners, especially those operating smaller vessels, should avoid sailing in these conditions.
