People keep on comparing this to Katrina without understanding the Houston Region.
1. Houston is not a bowel and once the rain stops the water will flow right on out.
2. This Hurricane is the worst ever to hit Texas and make Katrina look like a Tropical Storm.
3. Turner, Emmett and Abbott will do the right thing. Had people gotten stuck on 10 going West or 45 going North then people will scream they messed up and killed people.
So this is a damn if you do damn if you don't scenario...
Imagine if N.O. got the rainfall we did with Harvey....
"If you look at the observed precipitation maps for both Rita and Katrina, the total rainfall range is between 10 and 12 inches for both storms. Looking at AHPS for rainfall estimates, Hurricane Rita dropped more rain over the Lake Charles area than Katrina did over New Orleans.
Looking at the storm total radar images from IDV, it seemed that Rita dropped more rain in total (because of the lighter blue areas), however, the scale for Rita only goes from 0-15 inches, whereas for Katrina the scale goes from 0-24 inches. Taking these into account, it seems that both hurricanes dropped about the same amount of rain in total.
Looking at the precipitable water maps, Hurricane Katrina definitely had more moisture than Rita, but looking at the storm totals from NWS, the Lake Charles area received about 2 inches of rain more than Katrina.
Overall, after looking at all the radar images and rain gauge data, it seems that both hurricanes dropped about the same amount of rain, but Rita might have dropped a little bit more because the data seems to fit better for Rita. That being said, Katrina was definitely the more powerful and devastating hurricane because the levees broke and caused even more extensive damage."
N.O. would no longer be habitable.
