Harvey: gathering the lessons.

1. The facts.
a) Harvey became a cat 4 storm before it struck Texas, west of Houston.
b) The landfall occurred between two high pressure centers that blew winds south. Harvey then stalled, but the outer band on its east continued to pump moisture inland.
c) Predictably, the resultant deluge (some 50 inches of rain in some places) could not drain south and inundated the Houston metropolitan area and smaller towns.
d) Federal, state and local resources were marshaled to rescue citizens caught up in the flood. Help came from as far away as Louisiana (the Cajun Navy with its 'air' boats).
e)  There was also a heroic effort to rescues pets and some live stock.

2. The reporting.
On one hand, the reporting was adequate, with the exception of the ambulance chaser claims that the severity of the storm (and flooding) was due to 'global warming'. There was also an attempt by the Media to accuse Pres Trump of being uncaring. These attempts were despicable, the efforts of deranged Trump haters.

3. The damage.
There was storm damage and damage from the flooding and from loss of economic activity. Preliminary estimate is $90B.

4. Problems to be fixed.
There is a suggestion that Houston's drainage system needs improving.
