Tropical Storm Fay is now a hurricane but still poses no threat to Florida.
The same fate is expected of Tropical Storm Gonzalo, which is projected to become a hurricane this week.
Fay was 290 miles northeast of Bermuda on Sunday when winds increased to 75 mph making it a hurricane.
"It won't stay that way for long, since it is encountering strong shear and is moving east northeast at 25 mph," said Bay News 9 meterologist Diane Kacmarik.
Fay knocked out power Sunday for thousands of people in Bermuda as it lashed the British chain of islands with heavy rain and gusting winds before moving out toward the open Atlantic.
There were no immediate reports of injuries or deaths.
The storm disrupted power for more than 27,000 customers of the Bermuda Electric Light Co. The utility is the sole supplier of electricity for the territory of roughly 65,000 inhabitants.
Fay downed trees and utility poles and several roads were blocked across the tiny archipelago, which has one of the highest per capita incomes in the world and enforces strict building codes to ensure homes can withstand intense weather. Bermuda's public works ministry urged residents not to venture out on the roads.
A low pressure system east of the Leeward Islands has developed into season's seventh named storm.
Tropical Storm Gonzalo had maximum sustained winds of 45 mph Sunday afternoon about 125 miles east of Guadeloupe in the Leeward Islands. Moving west at 10 mph, it would be worrisome for Florida if not for a cold front expected to move down the state Tuesday and eventually steer the storm north.
"This storm is encountering little shear, so it is expected to intensify as it moves west," Bay News 9 meteorologist Diane Kacmarik said.
