Development Possible In The Central Atlantic; A Long Time To Watch

We’re entering the active time of hurricane season. Now is when tropical wave after tropical wave starts rolling off the coast of Africa. We often have a long time to watch each disturbance before it comes anywhere close to the U.S. mainland. As we always say, it’s a marathon, not a sprint.

As of Thursday evening, Invest 96L was about 1100 miles east of the Lesser Antilles. The National Hurricane Center currently gives this a 20% chance of tropical development in the next 2 days, 70% in the next 5 days.

In the short term it’s going to be battling an area of dry air and Saharan dust to its north. If it can overcome this, there’s a decent chance we’ll have a tropical depression form over the weekend a few hundred miles east of the Caribbean Sea.

It’s far too early to say what happens beyond that, but it does appear that there will be several limiting factors (land interaction, pockets of higher wind shear, etc.) that this will have to overcome in order to be any threat to the U.S. Beyond 5-7 days, it’s tough to lend much credence to model output, but for what’s it’s worth, our longer term models are keeping this weak and steering it out into the North Atlantic later next week.

For now, we wait.

Moisture Moves in Friday from a Tropical Wave, Potential Development in Atlantic Next Week

The forecast hasn’t changed for the tropical wave in the Caribbean. It will continue to move northwest spreading heavy rain to portions of the Greater Antilles, Bahamas and then Florida. There is a very minimal chance of development as the wave turns northeast away from the East Coast early next week.

The wave will bring deep moisture to the state Friday into Saturday, increasing rain chances for Tampa. Heavy rain is all we can expect from this wave.

It is looking more likely the tropical wave in the Atlantic may develop early next week. It is currently a disorganized area of showers and storms battling dry air and strong winds. Winds become more conducive for organization about 5 days out as it moves west in the Atlantic. If it does become a tropical depression, it will still be several hundred miles to the east of the Lesser Antilles.
