"Beyond the issue of the actual landfall point -- for the past 2 days, the global models have been forecasting the re-development/intensification of the high pressure ridge over the central U.S. -- and then expands it towards the Gulf coast. What this means, is that after Rita moves inland Saturday morning, it will gradually slow down, then stall out over west central Louisiana - and then is forecast to drift SOUTHWESTWARD towards Houston by Monday. This type of motion would lead to extreme rainfall totals across much of Louisiana and the east-southeast areas of Texas following landfall. Tremendous, life threatening flooding could result from portions of Louisiana southwestward to the Houston area. Storm rainfall totals could easily exceed 20" in some locations."
Oh geez, I hate the fine print, and I'm a LAWYER!
