Still at Tropical Storm status as of Tuesday morning, Dolly is beginning to kick up a breeze on Texas's South Padre Island. The National Hurricane Center track has the storm coming in midday Wednesday, probably as a weak hurricane. In its path are the cities of the Rio Grande Valley - McAllen, Harlingen, and Brownsville, Texas, and Matamoros and Reynosa, Mexico.
The real threat from Dolly may not be storm surge, though the Padre Island resorts are bracing for it. The inland border cities, as well as Monterrey, Mexico, could see flooding from heavy rains. Monterrey is an industrial city of four million an hour's drive from the Rio Grande.
Hurricane Emily hit the same area of the coast as a Category Three storm in July 2005. While Dolly will almost certainly not be quite as strong, Emily could be a preview of the potential for this storm.
