New Tropical Wave, Invest 97L, will strengthen in the week ahead

We’ve been watching a few waves kick off the coast of Africa and Invest 97L has a good chance to form in the week ahead. The development odds have steadily been climbing for this area – now 80% in the next 7 days.

The yellow highlighted area, Invest 96L, is looking less impressive as it battles Saharan dust. This area will continue to weaken the next few days.

Behind it, the tropical wave emerging off the coast of Africa is producing a large area of storms just southeast of the Cabo Verde Islands.

This could become the first hurricane of the season as it moves west-northwest. There is a lot of runway for strengthening and conditions are favorable for this to become a tropical depression around the middle of this week.

It will face some challenges from dry air and dust over the Atlantic. But as it gets closer to the Caribbean, the atmosphere is more favorable for it to strengthen.

Currently trends favor a turn north that would keep this east of Florida and the East Coast given the upper steering pattern. It is too early for high confidence in any track and we will look for model consistency over the next few days.

This is about a week out so we will watch it evolve and keep you updated.

Erin is the next name in line. August 11 is the average date the first hurricane of the season forms in the Atlantic.

Tropics are waking up with several areas of possible development

Right on cue with the start of August, the tropics are showing signs of life with a few areas we’re watching in the Atlantic Basin.

One is several hundred miles off the SE coast, where an area of low pressure is expected to form in the next few days along a stationary boundary. This is actually the same front that helped spin up Dexter earlier this week.

There is a 10% chance of development in the next 2 days and 40% chance in the next 7 days. A tropical depression could form as the low drifts west then northwest.

Model trends lean towards low pressure forming offshore of South Carolina then drifting toward the North Carolina coast into this weekend.

Tropical downpours and an unsettled pattern will be in place from Florida to the Carolinas through the weekend.

Hurricane Hunters are set to fly there later this morning to gather the latest data on the disturbed area.

Water temperatures are plenty warm in this region of the Atlantic with mid 80s in some spots.

Meanwhile, a mid-level disturbance is expected to spin up near the Bahamas and South Florida late this week. This will drag tropical moisture across Florida as the area slowly moves north through the weekend.

This could try to organize in the Gulf next week but at this point, it looks to be a rainmaker more than anything as it drags more deep tropical moisture across the state.

Tropical Storm Dexter continues to move ENE through the Atlantic with no direct impacts to land as it passes north of the Azores. High surf and dangerous rip currents continue across the East Coast as it move away.

The average date our E named storm forms is August 22. The first hurricane of the season forms Aug 11 on average.

The main development region is also waking up. There’s a tropical wave in the eastern Atlantic that’s just below the plum of Saharan dust and has a decent chance to form.

The NHC is giving it a 20% chance to form in the next 2 days and 60% chance to form in the next 7 days.

High pressure will be the main steering flow and the brunt of the models guide this area north the next few days. There are some models that take a westerly trend and this can’t be ruled out.

As the area gets more organized, we’ll have a better idea of how the steering pattern will evolve and what the most likely track will be.

There’s another wave on the heels of this area that will emerge off the coast of Africa and also garner watching next week and the following.

These are typical areas for tropical development at this point in the season as dust breaks down and water temps reach heat up even more through August.
