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.

Watching Two Spots in the Atlantic



We are still monitoring two areas of possible development in the Atlantic, although neither look to bring any impacts to Florida. Odds of development have slightly decreased for each of them.

Off the east coast, a weak area of low pressure will have a small chance of developing into a named storm before merging with a front by the end of the weekend. This will be moving away from the US and weather model support for this occurring has gradually decreased over the past few days.

Invest 96L still has a medium (40%) chance of development within the next week.

Dry air has created a hostile environment for it to organize in the short term. This is reflected in today’s satellite imagery of the tropical wave.

There is now high confidence that a weakness in high pressure to its north will help steer this system into the central or west Atlantic next week. That turn would likely keep it far of the coast of the United States.

Next week, our attention will return to the Main Development Region of the Atlantic. Long range forecast models continue to indicate that several more tropical waves will be entering into this region in the middle of August. Nothing pertaining to these waves has been outline by the National Hurricane Center at this time.
