My sister and her family, and my mother used to live just north of Houston. My mom's dead now, but my sister and family are in Dallas. My sis texted me a pic of her former home, about 6' under water.
I do have some friends in the Houston area and haven't heard squat. I am sure they are OK.
They are evacuating Ben Taub, a level 1 trauma center with many ICUs. No small task, and can't fly out a single patient. Herculean operation.
Wife's uncle lives in Conroe, waiting to hear from him as Conroe got the mandatory evac order (yesterday ?).
Houston Mayor should have issued a voluntary evac order, with mandatory for the downtown area.
