Tropical Storm Yutu to pass near the Northern Marianas; Be Prepared in Case Storm Track Changes

The National Weather Service (NWS) - Guam Weather Forecast Office continues to monitor what is now Tropical Storm Yutu.

On its current track, Yutu will likely be approaching the Marianas Wednesday night, passing just north of Saipan Thursday morning as a Category 3 typhoon. Category 3 Typhoon is referred to as a “Strong Typhoon” with maximum sustained winds of 111-129 mph and peak gusts of 140-164 mph.
The closest point of approach to Guam is possibly Thursday morning, more than 150 miles away. The onset of damaging winds of 39 mph or more is not expected for Guam at this time. The maximum sustained wind prediction for Guam is 25 mph but could be as high as 30 mph with higher gusts. Worst conditions are expected Wednesday night and Thursday morning.
Rainfall amounts of 2 -3 inches is possible for Guam during the storm’s passage but could be more if the storm moves south of the current predictions.
There are no watches or warnings in effect for the Marianas at this time but this can change in the coming days. Keep alert for updates such as changes in forecasted track, erratic movement, more rapid forward movement, or more rapid intensification.
