The Galveston Flood hurricane of 1900 killed between 6 and 12,000 people and wasted Galveston. is that precedent enough? how about over 1200 in Katrina which flooded out New Orleans.
Too fact based for the MSM, they want everything to be about now and we found it, and you must believe us.
If the forecast verifies and locations do measure 50” of rain from Harvey, that is indeed unprecedented. Combine that with Houston being the fourth largest city in the U.S. the potential is there for a significant disaster. Katrina disaster was mainly due to man made levy systems failing in a city that was built below sea level, not the magnitude of the storm itself. Galveston disaster was all about not having the ability of knowing the severity of the storm and not evacuating due to not having radar/satellite, etc. These are completely different scenarios.... The NWS and NHC wording is definitely warranted.
And 4000+ in the Okeechobee Flood of 1928.
