Hurricane Gonzalo regained strength on Thursday, again reaching Category 4 as it swirled toward Bermuda, the U.S. National Hurricane Center said, prompting residents of the island to prepare for the second major storm in a week.
Gonzalo was about 485 miles (780 km) south-southwest of Bermuda early on Thursday, the center said, with maximum sustained winds of 145 miles per hour (230 kph).
The hurricane was expected to send large swells and potentially dangerous surf conditions to the U.S. East Coast on Thursday before bringing hurricane-force winds to Bermuda on Friday, forecasters said.
