Tropical Depression Two forms in the central Atlantic

21 Jul 2014, 5:19 pm

The second tropical depression of the season formed on Monday afternoon, but it may not be around for all that long.

T.D. Two formed on Monday afternoon a little over a thousand miles east of the Lesser Antilles, a north-south island chain extending south from Puerto Rico in the eastern Caribbean. A well-defined low rolled off the coast of Africa has spun up into a tropical depression, with maximum sustained winds of 35 MPH as of 5:00 pm AST (an hour ahead of EST). But Two may die off before it has a chance to become our second tropical storm of the season in the Atlantic, which would be named ‘Bertha’, if it can get that far.

T.D. Two is heading westward into an area unfavorable for further tropical development. High wind shear, or changing of wind with speed and direction, is expected to keep the system at depression strength and gradually weaken it into a rather ordinary low by Thursday, according to the National Hurricane Center in Miami. Still, interests in the eastern Caribbean, and particularly the central and northern Antilles (looking at you, Barbados) should keep a close eye on this storm- tropical systems don’t pay attention to our forecasts and like to rebel against them. Here’s a look at the National Hurricane Center’s official forecast track:

All that said, the significance in this system may be simply our first sign that the ITCZ (inter-tropical convergence zone) between Africa and the Caribbean may be starting to get rolling. This area – the huge gap between the coast of Africa and the Caribbean – becomes the railroad track for many tropical systems, especially once we’re in the meat and potatoes of tropical season (mid-August through September). Once tropical systems form, they’ll move along a similar track that T.D. 2 is expected to take, eventually potentially posing a threat to the U.S. and the Caribbean.

Most importantly, this is the time of year to begin your hurricane preparations if you live along the Gulf Coast or the Atlantic seaboard, if you haven’t already. Hopefully, T.D. Two will be nothing more than a gentle reminder that hurricane season is heating up. We’ll keep you posted with all the latest on WeatherNation and right here on weathernationtv.com

  1. I wonder if all that wind shear is being caused by the start of El Nino. El Nino sometimes is the cause of wind shear tearing apart of tropical systems & this may be the case.
