Tropical Storm Harvey has formed in the Atlantic, becoming the 8th named storm of the 2017 Atlantic Hurricane Season.

As of the 5pm advisory, Harvey had maximum sustained winds of 40 mph and was moving west at 18 mph.

Harvey was formerly Post Tropical Cyclone Nine before being upgraded to a tropical storm after an Air Force Hurricane Hunter plane flew through the storm Thursday.

The National Hurricane Center forecast has Harvey moving west through the Lesser Antilles and into the Caribbean this weekend as it strengthens a bit.

A tropical storm warning has been issued for Martinique, St. Lucia, Barbados, and St. Vincent and the Grenadines. A tropical storm watch is also in effect for Dominica.

Harvey is not expected to have any impact on Southwest Florida weather.

Behind Harvey in the Atlantic, a tropical disturbance dubbed Invest 92L, has favorable odds of developing. As of Thursday afternoon, the National Hurricane Center gave 92L a 60% chance of developing into a named system over the next 2 days as the system moves west northwest.

Invest 92L is expected to encounter an environment hostile to development thereafter, which could keep the system under control. At this point, it is too early to provide specifics on the forecast track and strength of this system.
