The nightmare in Houston is only getting started. The latest from the NWS has Harvey re-emerging over the Gulf and strengthening before making landfall a 2nd time and heading north:

This means rain totals might double over the next few days:

Reliable weather forecasts still show taking whatever rain has already fallen around Houston & **doubling it** over next 4-5 days pic.twitter.com/dTBlfBPRQK

Euro model shows another 20-30" of rain in Houston next 5 days – on top of 15-30" already. Unimaginable, unfair. https://t.co/CmvII4eqYS pic.twitter.com/JzEfjlE0Pf

There’s also a possibility of flooding in Galveston, Texas but from the bay side:
