34W upgraded to Tropical Storm Man-Yi

(Office of Homeland Security and Emergency Management) — The CNMI State Warning Point in coordination with the National Weather Service Guam Weather Forecast Office is monitoring what is now Tropical Storm Man-Yi as it makes its way towards the Marianas.

Man-Yi is slowly intensifying and is expected to make its closest point of approach to the islands of Rota, Tinian and Saipan Thursday afternoon.

As of 4 p.m. Wednesday, the center of Tropical Storm Man-Yi was located near 7.7 degrees North Latitude, 149.1 degrees East Longitude, placing Man-Yi at 515 miles south-southeast of Rota and 560 miles south-southeast of Saipan and Tinian. The system was moving west-northwest at 20 MPH, and is expected to maintain this motion through Friday, taking Man-Yi southwest of Guam on Thursday.

Maximum sustained winds have increased to 60 MPH. Man-Yi is expected to continue intensifying through Thursday possibly becoming a typhoon on Wednesday evening. Tropical Storm force winds extend up to 110 miles from the center.

Because of the anticipated threat posed by Tropical Storm Man-Yi, acting Gov. Victor B. Hocog  upgraded the island of Rota to Tropical Storm Condition II as of 2 p.m. Wednesday. Tropical Storm Condition II means damaging winds of 39 to 73 MPH are expected within 24 hours.

No tropical storm watches or warnings have been issued for the islands of Saipan, Tinian or the Northern Islands.

What to expect

East winds of 30 to 40 MPH with gusts to 50 MPH are expected for Rota, and 25 to 35 MPH on the islands of Saipan and Tinian. Winds will diminish and shift to southeast Thursday evening.

For the island of Rota, combined seas will increase and reach 10 to 12 feet by Thursday morning then further to between 12 and 14 feet Thursday afternoon and between 14 and 18 feet Thursday evening. This will create surf of 11 to 13 feet Thursday morning, 13 to 16 feet Thursday afternoon and 15 to 20 feet Thursday evening. Inundation of 1 to 2 feet is possible along eastern and southern shorelines.

For Rota, Tinian and Rota, rainfall amounts of 2 to 4 inches are expected through Thursday night. A flash flood watch may be needed if Man-Yi decreases in forward speed or moves farther north.
