How much rain is needed to end the drought in Houston?
SE Texas continues to see worsening drought conditions with the lack of rain. How much rain is needed and why haven't we seen it?

Houston has been waiting all month for rain, but this problem didn’t just start in October; it extends back several months. The lack of rain has led to extremely dry and drought conditions across SE Texas, causing state officials to issue burn bans in several counties, including Fort Bend.
The drought monitor is updated every Thursday, and this week, SE Texas is in for more bad than good. Colorado and Wharton County now have severe drought conditions. Elsewhere, it is abnormally dry or a moderate drought.
So why is Houston so behind in the rainfall department?
Hurricane season started in June, and this week marks the end of Houston’s tropical activity. All that time, we have not seen one storm make landfall in Texas.
