You are gonna be okay. You probably won't lose power wither. Eat the ice cream, zone out and hunker down. I told my mom in Austin to just get a couple of movies, take it easy and wait till everything passes over.
Just checking back in -- has Texas gone contraflow with those highways yet?
Volunteer are passing out water in the Houston area for folks trying to evac. They are using metro buses. Hot damn. The officials in Texas know how to manage stuff. I'm impressed!
