Houston Flooding

As much as ten inches of rain fell in Houston today. This wasn't a hurricane or a tropical storm, just a low pressure system moving across southern Texas. This low is being compared to Tropical Storm Allison, which hit Texas in 2001 and lingered for several days. Flooding is and will continue to be the biggest problem. There have been reports of torrential rains falling at the rate of 6 inches an hour, which is more than enough to cause flash flooding. The local forecast says that heavy rains could continue for the next two days, which will cause more persistance flooding. Local coverage can be found here and here.
