A tropical wave that didn’t look terribly impressive as it traversed the Atlantic from Africa to the Caribbean intensified into the 4th named storm of the 2011 season: Tropical Storm Don. Don is a small storm and is being impacted by dry air over the western Gulf of Mexico and northerly wind shear that isn’t allowing for a stacked system to develop.
All in all, that might be the best scenario for Texas, which is suffering through its worst drought in recorded history:
Brought about by climate change and La Nina, a drought of this magnitude can feed on itself by evaporating most of the soil moisture over a large area, thereby reducing the chance of thunderstorms to form and rain to fall. This is where T.S. Don comes in. If it stays on the small and weak side, downpouring rain and wind won’t be factors after landfall. A sizable amount of rain will still likely fall, but hopefully flooding won’t be as much of a problem as it would be if Don were much larger and stronger.
It will take a week or two after projected landfall (this Friday) to ascertain how much of an impact Don has on the Texas Drought.
