Update on Hurricane Dolly

Hurricane Dolly will be moving onshore near Padre Island, TX this morning. The storm has strengthened overnight as forecast and has now reached 100 mph - a category 2 storm. Radar presentation from Brownsville is pretty good and the ragged eye of the hurricane is evident. The storm will pound south Texas (Brownsville, Harlingen, McAllen, Port Isabel, and Padre Island) during the day and weaken slowly through tonight. The track takes the storm into the northern portions of Mexico tomorrow, with no affect on Mid-South weather. A couple of radar images captured about 7:30am CDT today are shown below.
