CAMP FOSTER, Okinawa — A new tropical depression formed well to the south-southwest of Okinawa on Wednesday, but it’s forecast to pass about 260 miles southeast of Okinawa by Friday, causing some rain and wind gusts.

Officials at Kadena Air Base’s 18th Wing Weather Flight said they were "keeping an eye" on Tropical Depression 04W, which at 8 p.m. Wednesday was 715 miles south-southwest of Kadena.

The new storm is forecast to curve sharply northeast Thursday, with winds forecast to peak at 52 mph sustained with 63 mph gusts.

If it becomes a named storm, 04W would be dubbed Chataan, a word in Guam’s native Chamoru language that means rain.
