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 US 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.
There was a chance Larry could track far enough west to pass close or over Bermuda, AccuWeather senior meteorologist Randy Adkins said. “However, as it currently stands, it appears more likely than not that Larry will still end up far enough to the east to spare Bermuda the brunt of the storm.”
Larry became the fifth hurricane – and third major hurricane – last week in an already-rough Atlantic hurricane season: 12 named storms. The season runs from June 1 through November 30; the peak is Friday.
“We’re running well ahead of schedule, especially for named storms,” Colorado State University hurricane researcher Phil Klotzbach told USA TODAY. On average, through August 31, there would usually be about six named storms, which includes both tropical storms and hurricanes, he said.
Leading hurricane forecasts from AccuWeather and Weather.com agree that 2021 will experience higher-than-normal activity.
Larry could last well into the second week of September and become the longest-lived named system so far this season, Accuweather said.
In the Ida-battered Southeast, forecasters were watching a brewing system forecast to move northwestward over the southwestern Gulf of Mexico on Sunday, then slowly northward or northeastward over the western or central Gulf. Upper-level winds were only expected to be “marginally conducive” for tropical cyclone formation, the hurricane center said, but some slow development is possible. Even if tropical development doesn’t materialize, the system could bring heavy rains midweek.
