Harris County Office of Emergency Management has a cool rainfall map for Houston. You can actually look at the rainfall in a particular area and when you click on the little rainfall numbers you can see if byous are over their banks.
Kingwood, where I live was one of the heaviest rainfalls in the area. But we really didn’t have much flooding. Lots of roads were flooded on the way to work. Based on water lines, there was a foot of water in the parking lot of our office. Another two or 3 inches of water and it would have flooded the offices.
Went out an looked at the roof over the closet that was leaking last night. There is a vent pipe or something coming out of the roof, though not right over the place the leak is. Maybe that is leaking and not the whole roof. Guess it wouldn’t be the whole roof anyway.
