Tropical Storm Humberto keeps strengthening and has almost become a hurricane, with maximum sustained winds of 70 mph, the National Hurricane Center in Miami said.
As of 5 p.m., Humberto was moving northwest at 8 mph about 245 miles west of the southernmost Cape Verde Islands.
It could become the first hurricane of the 2013 season Tuesday night or on Wednesday, according to the National Hurricane Center.
A turn toward the north-northwest at a faster speed is expected on Wednesday, 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 are occurring on Bermuda as the reformed Tropical Storm Gabrielle nears the island. A tropical storm warning was in effect for Bermuda, which Gabrielle was expected to pass over or near in the next few hours, according to the NHC.
Gabrielle, which formed and dissipated last week, regenerated Tuesday morning near Bermuda. By 8 p.m., it had maximum sustained winds of 60 mph as it moved north at 10 mph about 45 miles south-southwest of Bermuda.
Gabrielle was expected to keep moving north Tuesday night, then turn toward the north-northwest with a decrease in speed on Wednesday.
Gabrielle is expected to pass over or near Bermuda by Wednesday morning and some strengthening is forecast over the next 48 hours, according to the NHC.
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.
