(Reuters) - Hurricane Chris gathered strength as it churned off the coast of the Mid-Atlantic states to become a Category 2 storm on the Saffir-Simpson wind scale on Tuesday, but it was not expected to make landfall over the United States, the U.S. National Hurricane Center (NHC) said.
Chris was packing maximum sustained winds of 105 miles per hour (165 km per hour) and was about 245 miles (390 km) east-southeast of Cape Hatteras, North Carolina, on Tuesday evening, the NHC said in its latest advisory at 11 p.m. EDT (0300 GMT).
The hurricane was moving toward the northeast at 10 mph (17 kph), the NHC said.
The storm was expected to strengthen through Wednesday and then lose force from Thursday, the center said.
Storm swells generated by Chris will be hitting North Carolina and other mid-Atlantic states over the next few days. "These swells could cause life-threatening surf and rip current conditions," the center said.
North Carolina Governor Roy Cooper warned beachgoers on Monday to beware of dangerous rip currents after an unidentified man in his mid-60s drowned just north of the town of Nags Head, near Cape Hatteras, when he was caught in a rough surf current caused by the storm.
Chris was expected to remain well off the U.S. coast, the NHC said, adding on its current forecast track, the center of Chris will be near southeastern Newfoundland on Thursday night.
The storm was forecasted to dump as much as 6 inches (150 millimeters) of rain over parts of Newfoundland, which could cause flash flooding, it said.
