Posted on May 22 2012
The tropical depression intensified yesterday afternoon into a tropical storm even as it moved northwestward away from coastal waters of the Marianas.
As of 5pm, Tropical Storm Sanvu was still churning northwestward at 12 miles per hour with maximum sustained winds of 45 mph, according to the Emergency Management Office and the U.S. National Weather Service in Guam.
At that time, Sanvu’s center was 130 miles west-northwest of Guam, 155 miles west of Rota, 190 miles west-southwest of Tinian, and 200 miles southwest of Saipan.
A tropical storm warning at that time was still in effect for Guam and Rota, while a tropical storm watch was also still in effect for Tinian and Saipan.
Tropical storm warning means that tropical storm conditions are expected within the next 24 hours. NWS said all persons in the warning areas should already have preparations underway to protect life and property.
Tropical storm watch means that tropical storm conditions are possible within the next 48 hours. NWS said all persons in the watch areas should review their preparedness plan and be ready to implement it should a warning be issued for their area.
Both tropical storm warning and tropical storm watch were cancelled at 8:30pm last night.
The tropical storm’s center was at its closest to the Marianas at 7am yesterday—60 miles southwest of Guam, 115 miles southwest of Rota, 180 miles southwest of Tinian, and 195 miles southwest of Saipan.
The storm brought numerous showers and isolated thunderstorms in the morning until last night, Tuesday. NWS said that scattered showers and isolated thunderstorms will linger into Wednesday night in the region.
