July 21 (Bloomberg) -- Dora, a Category 4 hurricane off Mexico’s Pacific coast with top winds of 140 miles (225 kilometers) per hour, will weaken gradually while tropical storms Bret and Cindy are forecast to lose strength in the Atlantic.
Dora eased from an earlier speed of 155 mph and “slow weakening” is expected tonight, with a more rapid decrease in winds tomorrow, the U.S. National Hurricane Center said in an advisory at 8 p.m. New York time. The storm is forecast to remain offshore, the agency said.
The hurricane was about 360 miles south-southeast of Cabo San Lucas and heading northwest at 9 mph. Hurricane-force winds extend up to 50 miles from Dora’s core.
High surf will affect the southwestern Mexico coast for the next few days and start to hit the Baja California Peninsula later tonight, the center said. The Mexican government issued storm watches for the southern peninsula from Agua Blanca to Buenavista, including Cabo San Lucas, according to the center.
In the Atlantic, Cindy was about 995 miles west-northwest of the Azores and moving northeast at 28 mph with top winds at 60 mph, the center said. The storm poses no threat to land and should start to weaken overnight as it hits colder water, the center said.
Bret to Weaken
Bret, with maximum winds of 40 mph, may become a tropical depression overnight, the center said. The system was 335 miles east of Cape Hatteras, North Carolina, moving east-northeast at 10 mph.
An area of showers and thunderstorms 650 miles east of the Windward Islands has a 10 percent chance of becoming a tropical depression or tropical storm in the next two days, the center said in a weather outlook at 8 p.m. The system is moving west-northwest at 15 to 20 mph.
A disturbance becomes tropical when it develops a cyclonic rotation, becomes a named storm when sustained winds reach 39 mph and attains hurricane status when winds quicken to 74 mph. A Category 4 hurricane has sustained winds of 131 to 155 mph.
