Just days after Hurricane Ida left a staggering, multi-state trail of destruction, forecasters were keeping a wary eye Sunday on another storm steaming across the Atlantic that could be even more ferocious.

Larry, now a Category 3 hurricane, could intensify into a Category 4 storm, possibly by Sunday, Accuweather meteorologists said. A Category 4 hurricane, as Ida was when it made landfall in Louisiana, has sustained winds of 130 to 156 mph. If Larry’s sustained winds increase above 150 mph, it would become the strongest storm in the Atlantic this year – even stronger than Ida, Accuweather said.

The storm was expected to churn across the open waters of the Atlantic for several more days, but it could eventually approach Bermuda around the middle of the week and move close to North America, Accuweather said. “At this point, it is most likely that Larry will miss the United States and stay a few hundred miles away from the Northeast coast,” Accuweather said.

Still, much of the eastern U.S. coast could feel Larry’s effects by midweek: Major swells from the storm are “likely to cause life-threatening surf and rip current conditions,” the hurricane center said.

Larry was located about 830 miles east of the Northern Leeward Islands on Sunday afternoon, moving to the northwest at 13 mph. Maximum sustained winds were 125 mph, with higher gusts, the National Hurricane Center said.

“Little change in strength is forecast during the next few days, although fluctuations in intensity will be possible. Larry is expected to remain a major hurricane through the middle of this week,” the center said.

The storm is a large hurricane, the center said: Hurricane-force winds extend outward up to 45 miles from the center and tropical-storm-force winds extend outward up to 175 miles.
