I just got an email from one of my friends in the Houston area. She and her family are fine. They were only without power for about 16 hours or so - when they'd been told they could be without power for up to 2 weeks! They had some damage to their carport and greenhouse from a tree falling, but no water damage. They were up all night, of course, but other than that, all is well with them.
The other family actually got some sleep, and no damage at all to their house. Praise the Lord for His protection over our friends!
Sibyl left a comment that she lives in Houston. Hope all went well with her too.
