Tropical Storm Humberto remained a tropical storm with maximum sustained winds of 70 mph Tuesday night, but the National Hurricane Center in Miami forecasts it to become a hurricane Wednesday.
As of 11 p.m., Humberto was moving northwest at 7 mph about 270 miles west of the southernmost Cape Verde Islands.
It is expected to strengthen during the next 48 hours. If it does become a hurricane on Wednesday, it would be the first of the 2013 season.
A turn toward the north at a slightly faster speed is expected during the next two days, with Humberto forecast to head northward Wednesday night and Thursday.
There were no coastal watches or warnings in effect for Humberto.
Meanwhile, tropical storm conditions were occurring on Bermuda as the reformed Tropical Storm Gabrielle slowed as it neared the island. A tropical storm warning was in effect for Bermuda, which Gabrielle was expected to pass near or just west of overnight, according to the NHC.
Gabrielle, which formed and dissipated last week, regenerated Tuesday morning near Bermuda. By 11 p.m., it had maximum sustained winds of 60 mph as it moved north at 8 mph about 25 miles south-southwest of Bermuda.
Gabrielle was expected to turn toward the north-northwest with a decrease in speed overnight or early Wednesday.
A storm surge of two to three feet above normal tide levels is expected on Bermuda and rough surf conditions will continue to affect Bermuda through Wednesday. Rainfall will be between two and four inches with isolated maximum totals of six inches possible.
