My family in Conroe drove quite away to be able to use the cell phone yesterday. They said that it probably will be weeks before they have the power on.
My nephew is a teacher, and said that the schools could be closed for two weeks.
Other parts of the Huston area didn't lose power at all.
We were without power for a week after Tropical Storm Isabel slammed into our part of Maryland in 2003. Fortunately, we had redone our kitchen two years before and had installed a new SubZero refrigerator freezer. We used a portable generator to run our "Christmas refrigerator" (named for the only time of year we normally ever use it) in the basement and never opened the SubZero. When the power came back on, we finally opened the freezer door to find all of our frozen food still frozen and ice cubes in the bin.
Moral of the story: modern freezers will do a remarkable job for you if you can give them half a chance.
