Be careful and be safe. Evacuee centers are open in San Antonio and can accomodate quite a few people, though some still have Katrina folks. If anyone is evacuating to the San Antonio area, watch for info signs, they will tell you where to call for evac center locations.
Even so, San Antonio (and areas East where I live) may experience very heavy rain and some wind, possibly power outages. Flooding is possible in New Braunfels and Seguin, just like 1998 and 2000. Major damage, like New Orleans, is unlikely in our immediate area though, unless we get a tornado or something. Right now we are predicted to be on the softer side of the storm, assuming it goes to Galveston/Houston. If it hit Corpus Christi instead, we may get a LOT of rain.
Please, everyone, evacuate if directed to do so, don't risk it.
