A strong monsoon surge in western Micronesia has created large southwest swells that are headed to the Marianas and will create hazardous sailing conditions for small craft through at least Tuesday night.
A small craft advisory is now in effect until 6am Wednesday.
Based on the information received from the National Weather Service in Tiyan, Guam, and compiled at the CNMI Emergency Operations Center State Warning Point, seas of 5 to 7 feet will build to 8 to 10 feet and southwest winds of 10 to 15 knots will increase to 15 to 20 knots, with frequent gusts to 25 knots and occasional gusts of 30 knots.
A small craft advisory means that wind speeds of 22 to 33 knots are expected to produce wave conditions hazardous to small craft.
Inexperienced mariners, especially those operating smaller vessels, should avoid sailing in these conditions. (PR)
