Is it going to flood?
Houston isn't very much above sea level and when it rains we depend on our sluggish streams and bayous to drain the water out to the Gulf of Mexico. It is a delicate equilibrium between the size of the streams and the amount of the rainfall per hour. Sometimes, like during Tropical Storm Allison in June of 2001 when the city was overwhelmed with 10 to 30 inches of rainfall in a 24 hour period, streets and freeways go under water, 18 wheelers float in the freeways and houses are flooded. So you don't have to live in Houston too long until you come to respect heavy rain. Yesterday, I was out shopping when the black clouds rolled in, thunder rumbled and the wind gusted. I headed for home.
