Quiet in the Atlantic; total eclipse darkens Asia

By: Dr. Jeff Masters, 1:42 PM GMT on July 22, 2009

The strong tropical wave (97L) we've been tracking all week has now moved over the Bahamas, and remains disorganized, thanks to 30 knots of wind shear and a traumatic encounter with the island of Hispaniola. This wave should remain disorganized for at least the next two days, thanks to high wind shear.

The new tropical disturbance north of the central Bahama Islands is lifting northwards towards the Outer Banks of North Carolina. This morning's QuikSCAT pass showed winds of 30 - 35 mph, but no evidence of a closed circulation. This region is under about 20 - 25 knots of wind shear, and has the potential for some slow development over the next few days as it moves northwards, parallel to the coast. This low probably does not have enough time over warm water to reach tropical depression status. None of the computer models are showing any tropical development over the next seven days, though the tropical disturbance north of the central Bahamas may develop into an extratropical storm capable of dumping heavy rain on the Canadian Maritime provinces late this week.

I won't be making a post Thursday, since I'll be traveling. Wunderground's severe storms expert, Dr. Rob Carver, will make a post if a new Invest pops up. Dr. Carver has started his own blog--check out his cool satellite loops of this morning's total eclipse in Asia.
