Highly localized yet widely distributed pockets of disaster in Houston

[From a post I left on Facebook at 2:04 a.m. on Tuesday, August 29, 2017:]

Network and local TV tonight are showing lots of video from the George R. Brown Convention Center on the east side of downtown, where something close to 10,000 Houstonians are temporarily sheltering, roughly five times as many as there were last night. Kudos to the City personnel who're handling that.

But consider: The George R. Brown Convention Center is an easy five-minute drive or 15-minute walk, less than a mile, from Buffalo Bayou, which has left its banks to utterly flood parts of downtown Houston, including the area on the northeast side of downtown that contains most Harris County buildings (including the Civil Courts Building).

That vividly illustrates just how incredibly LOCALIZED yet DISTRIBUTED this disaster is. Some of the greatest disaster scenes are only a few hundred yards away from some of the beacons of shelter and safety. That's just the nature of this flood. The good news is that evacuees don't have to flee half-way across Texas to be safe, or even half-way across Houston (for there are other shelters more convenient than the Brown for many other evacuees).
