Potential tropical cyclone forms in Atlantic; 2nd system closer to Fla

Update: Tropical wave has 60% chance of becoming tropical depression

NHC: 50% chance of weather system developing into tropical depression

The government of the Cabo Verde Islands issued tropical storm warnings for Santiago, Fogo and Brava.

Once this tropical wave passes Southwest Florida and moves into the Gulf of Mexico, the environment could become more favorable for development, so it's still one we want to track closely in the NBC2 First Alert Hurricane Tracking Center.

Assuming the system becomes a tropical storm, the next name on the list is Florence.

It brought with it wave heights of 17.81 metres, top gusts of 191 km/h and sustained winds (10-minute mean) of 111km/h when it hit the country in October.

Watch for storms with frequent lightning and heavy downpours.

The system, dubbed Invest 90L, would be named Florence if it becomes a tropical storm.

Invest 90L, which is moving off the coast of Senegal, has an 80 percent chance of forming into a tropical system as it moves west or northwest at 15 miles per hour.

Sea surface temperatures have warmed from their unseasonably cooler status earlier this year and the dry Saharan air, which is known to discourage tropical development, is north of where this system is about to emerge. "This time of the season is also termed the "Cape Verde Island" season, due to the waves developing near those islands off the African coast".

Of more immediate concern to South Florida is whether Labor Day weekend will be a washout.

There is a high chance that this will develop into a tropical cyclone Friday as it moves west.

The chance for showers falls slightly for Friday, but picks back up for our holiday weekend.
