Tropical Storm Julia grew in the far eastern Atlantic into the fifth hurricane of the storm season, while Hurricane Igor weakened slightly but remained a dangerous Category 4 storm, forecasters said on Tuesday.
Neither hurricane posed an immediate threat to land or energy interests, but Igor could threaten Bermuda by the weekend.
Julia reached hurricane status and then continued to strengthen, with top sustained winds of 85 miles per hour. It was about 355 miles west-northwest of the Cape Verde Islands at 11 a.m. EDT (1500 GMT), forecasters at the U.S. National Hurricane Center in Miami said.
Julia was moving west-northwest as a Category 1 hurricane on the five-step Saffir-Simpson scale of hurricane intensity, forecasters said. Its projected path would keep it out to sea.
Julia could strengthen slowly over the next two days, forecasters said. But as it gets closer to the more powerful Igor, strong upper-level winds flowing out from Igor could shear off and weaken Julia.
Farther west in the Atlantic, Hurricane Igor weakened slightly but still packed a punch, the center said.
Igor was about 710 miles east of the northern Leeward Islands with maximum sustained winds at 135 mph, the center said.
