(NEW YORK) — Humberto picked up some steam Wednesday morning, strengthening enough to become the first hurricane of the Atlantic season.
The former tropical storm is now a Category 1 hurricane with maximum sustained winds of 75 miles per hour.
As Jack Beven at the National Hurricane Center in Miami points out, it’s unusual to wait until September for the first hurricane of the season.
“As far as we can tell this is probably the second latest formation of a hurricane in the period of reliable records in the Atlantic basin. But we have to do a little more research on that to be sure,” he says.
According to the National Hurricane Center’s latest advisory, Humberto is located about 310 miles west northwest of the southernmost Cape Verde Islands and moving north northwest at 8 mph.
While the storm has the potential to strengthen further on Wednesday, Beven says it may not be a hurricane for long.
“After a day or so we anticipate Humberto will move into an area of less favorable conditions. It will probably weaken significantly for the rest of our five-day forecast period,” Beven says.
