Strong Convection as Tropical Depression 7 Forms in Atlantic

At 11 a.m. EDT, System 96L strengthened and was designated the Atlantic Ocean Hurricane Season's seventh tropical depression (TD7). At that time, TD7 had maximum sustained winds near 35 mph, and is expected to strengthen into a tropical storm. If TD7 does strengthen, it would become Tropical Storm Earl.

TD7 is still in the far eastern Atlantic Ocean, about 430 miles west of the southernmost Cape Verde Islands, near 14.3 North and 30.8 West. It is moving west near 17 mph, and has a minimum central pressure of 1007 millibars.

By this morning, August 25, TD7 has "well-defined cyclonically-curved convective bands...and an established upper-level outflow in the western semicircle," according to the National Hurricane Center. That means that the depression is getting organized.

TD7 is expected to become Tropical Storm Earl later today, especially because there are unusually warm waters in the tropical Atlantic that will help fuel its development. AIRS data showed that the waters are over the 80 degree Fahrenheit threshold needed to power tropical cyclones.
