As of 11 p.m. ET Tuesday, the center of Hurricane Gert was about 360 miles to the west-northwest of Bermuda.
Gert is moving toward the northeast at 15 mph. Maximum sustained winds have increased to 85 mph with higher gusts.
Hurricane-force winds extend outward up to 25 miles from the center. Tropical-storm-force winds extend outward up to 115 miles from the center. The estimated minimum central pressure is 979 mb.
Some additional strengthening is possible Tuesday night and Wednesday. After that, Gert is expected to weaken with the cyclone becoming an extratropical low by Thursday night.
The system will be capable of creating rough surf and enhanced rip currents across the Carolinas up through Long Island, New York, but it's otherwise not expected to impact the U.S.
Elsewhere, we're monitoring three other areas in the tropics.
The first wave is an elongated area of low pressure more than a thousand miles east of the Lesser Antilles. It's producing disorganized showers and thunderstorms and is expected to move west at about 15 to 20 mph across the Atlantic before crossing into the Caribbean Sea by Friday. Environmental conditions could become more conducive for further development over the next few days but should become less conducive as it moves into the Caribbean due to added shear.
A second area of low pressure we are watching is also producing some disorganized thunderstorm activity a few hundred miles to the southwest of the Cabo Verde Islands. Environmental conditions could be conducive for some slow development throughout the next few days as it moves to the west-northwest across the Atlantic. However, upper-level dynamics are expected to be less conducive for development by the time we move into the weekend.
The third area we are monitoring is a tropical wave over western Africa that is expected to emerge over the Atlantic Ocean sometime tomorrow. Again, conditions seem generally conducive for some tropical development as it moves to the west-northwest across the Atlantic at 15 to 20 mph.
