For those of you just waking up to the news – an unprecedented flood is underway across the Houston Metro. Rainfall amounts of nearly 30 inches have fallen across parts of the Houston metro over the last 24 hours – over half of it within the last 8 hours. Houston is under water in what will become the worst flood event in Texas state history and one of the worst United States flooding disasters in modern history. Additional rainfall totals of 20 to 30 inches are expected through Thursday – for a storm total of 45 to 60 inches in parts of Southeast Texas. This is only the beginning of this flood event and I’m afraid that we truly cannot imagine how much more severe it will become. An additional five to ten inches of rain is expected by the afternoon hours. There may be a bit of a break for Houston this afternoon, but weather models indicate another night of very heavy rains tonight into Monday morning. Absolutely no one should be going to Southeast Texas for the next several days unless you are an emergency responder or responding to assist in this emergency situation. This event is unlike any other flooding event we’ve seen in Texas. No longer will Allison be the ‘worst case scenario’ for Houston, for Harvey has become the mother of all diasters.
