More flooding later this week?
As rounds of rain come through and fall on already saturated grounds, more street flooding is likely – especially Friday and Saturday. We’ll just have to watch and wait to see which area watersheds get the most rain and which creeks and bayous threaten to flood. The current forecast calls for rainfall totals of 3 to 4 inches along the coast, 4 to 5 inches in Houston and 5 inches in College Station and Huntsville.
Houston’s Public Works Dept. has already said it will lower the water levels in Lake Houston to prepare for the possibility of heavy rain.
Here’s what to expect this week…
