JACKSONVILLE, Fla. – A non-tropical area of low pressure has formed over the central Atlantic Ocean a few hundred miles east of Bermuda. Development of this system as a subtropical cyclone appears unlikely due to unfavorable environmental conditions, and the low is expected to dissipate in a few days.
The formation chance through 48 hours is low at 10 percent.
The formation chance through 5 days is equally low at 10 percent.
If conditions were to change and the system were to develop into a Tropical Storm, it would be the 4th of the 2020 Hurricane Season and would be named Dolly.
The NHC forecast discussion for the Atlantic describes the unfavorable conditions in the area currently,
Low pressure has formed E of Bermuda near 30N58W of 1010 mb along a cold front that extends SW to 25N67W then NW to 31N76W. Scattered moderate convection is along this front to the E of 66W. Moderate to fresh SW winds and seas to 8 ft are noted in this same area. A pre-frontal trough is analyzed from 28N57W to 23N63W. Elsewhere west of 50W, gentle breezes and 3 to 5 ft seas are observed.
For the forecast, the low pressure E of Bermuda will drift NE and gradually weaken into late week. The front will sag south and east through tonight, then stall north of the Antilles and over the Bahamas Wed into Thu. High pressure will build in behind the front and be the dominant weather feature through late week.
Farther east, broad ridging dominates the eastern Atlantic, anchored by a 1029 mb high over the Azores near 40N30W.
