Based on information received from the National Weather Service in Tiyan, Guam, and compiled at the CNMI Emergency Operations Center-State Warning Point, Doppler radar and satellite imagery indicated that squall lines over Guam and Rota waters have shifted northward. These squall lines are moving from Rota waters into Tinian and Saipan waters. They are capable of producing thunderstorms and wind gusts of 25 to 35 knots at least for the next two hours.
Mariners can expect gusty winds, high waves, and possible dangerous lightning and visibility of down to one-half mile in heavy showers.
The EOC is advising the public and inexperienced mariners, especially those operating smaller vessels, to avoid sailing in these conditions. Inexperienced mariners should move to safe harbor immediately or stay close to shore until conditions have improved. (EOC)
