MIAMI (AP) — Forecasters say Hurricane Bertha has weakened to a Category 1 storm and is moving slowly toward Bermuda but could re-strengthen in the next 24 hours.

Forecasters have been urging people on the island to monitor the storm's progress. They say Bertha has started producing large swells and high surf there.

It's still unknown if or when the hurricane will make landfall. If it stays on the current track, Bertha will slowly approach Bermuda today and Saturday.

As of about 11 p.m. EDT Thursday, the center of the storm was about 385 miles southeast of Bermuda.

Maximum sustained winds were about 85 mph with some higher gusting.

The Atlantic season's first hurricane is traveling northwest at about 8 mph. It's expected to turn north and slow down in the next couple of days.
