A typhoon watch remains in effect for the far northern CNMI islands of Agrihan, Pagan and Alamagan.
As of 1 am this morning tropical storm Fengshen was located about 440 miles east northeast of Saipan moving west at 20 mph.
It had maximum sustained winds of 50 mph.
The forecast track has the storm passing over Pagan late tonight or early Friday morning as a severe tropical storm.
The weather service expects little or no impact across Guam, Rota, Tinian or Saipan, other than a slight increase in showers and thunderstorms tonight and Friday. There are no watches or warnings out for those lower islands.
Fengshen is a mandarin word for god of wind.
