Two tropical depressions expected by the weekend

two_atl_5d0HOLT, Fla., Sept. 6, 2018—Two tropical disturbances in the eastern Atlantic Ocean are projected to develop into tropical depressions.

storm_92An area of low pressure is centered about 500 miles west of the Cabo Verde Islands.

Environmental conditions are favorable for further development and a tropical depression is expected to form within the next day or two while the system moves slowly west across the tropical Atlantic Ocean.

A second tropical wave and an accompanying low-pressure system near the west coast of Africa is producing a large area of thunderstorms.

storm_93Environmental conditions also appear favorable for development and a tropical depression or tropical storm is likely to form during the weekend while the wave moves west or west-northwest over the far eastern tropical Atlantic Ocean.

Potential tropical cyclone advisories could be issued Friday for the islands.

Formation chance through five days for both is high at 90 percent.

Meanwhile, Florence is clinging to hurricane status.

Wind shear has taken a toll on Florence and is expected to remain strong, which should continue Florence’s weakening trend, potentially taking the system below hurricane strength, according to the National Hurricane Center.

Continued weakening is forecast during the next day or so followed by re-strengthening late Friday into this weekend.

Florence shouldn’t have any problems restrengthening beginning in a day or so, according to the NHC. Guidance suggests Florence could once again become a major hurricane in four or five days.

Florence is moving toward the northwest near 10 mph and a turn toward the west is expected tomorrow.

A west-to-west-northwest motion should continue into early next week.

Maximum sustained winds are near 80 mph with higher gusts.
