UPDATE 5 p.m.

While there is still no current threat to Hawaii, Hurricane Calvin is “quickly strengthening” with sustained winds near 100 mph, according to the National Hurricane Center.

Calvin’s sustained winds have strengthened over the course of the day, and “some additional strengthening is forecast during the next day or so,” the hurricane center said in a 5 p.m. update.

While it’s moving toward Hawaii at a pace of 15 mph and is expected to move in a “west to west-northwestward motion” for the next few days, Calvin is still more than 2,000 miles away from Hilo.

There are currently no coastal watches or warnings in effect.

Calvin is expected to start gradually weakening during the weekend as it reaches cooler waters, the NHC said.

Hurricane Calvin continues to strengthen as it moves in the East Pacific, but forecasters predict a gradual weakening this weekend as it moves over cooler water toward the Hawaiian Islands.

As of 11 a.m. today, Calvin was located about 905 miles southwest of the southern tip of Baja California.

Calvin was packing maximum sustained winds of 80 mph. The hurricane was moving toward the west near 14 mph and a west-to-west-northwestward motion is predicted to resume over the next few days.

Hurricane-force winds extend outward up to 25 miles from the center and tropical-storm-force winds extend outward up to 80 miles, according to forecasters.

The next update is expected at 5 p.m. today.
