Jason Beaman from NWS Memphis is speaking on mid-south (Memphis area) impact from Rita and Katrina...
Katrina tracked across the far SE part of the Memphis NWS CWA (county warning area)
7 hours of tropical storm force winds at Tupelo
Lowest pressure.... 980 mb at Tupelo
Rainfall 4 to 8 inches
Damage was mostly from trees falling on structures
100,000 plus customers without power
Flash flooding issues
Lowest pressure at Memphis was 989 mb
Rita tracked west of Memphis. Initial forecast ideas of Rita stalling did not happen.
Wind gusts were higher in Memphis from Rita. Gusts produced by convective bands with 50 to 55 dbz cores.
Upper circulation was strong; convection brought down the higher winds to the surface
Best heading of a tropical system for tornadoes is 010 to 040 degrees. This was the case with Rita
Most of the tornadoes from Rita were just west of the Memphis CWA (we all know where they were... 10 tornadoes in Tuscaloosa County September 25
A group from the University of Louisiana at Monroe is now doing a presentation on a project involving making remote measurements from the field during Katrina and Rita. Two meter towers were set up across South Louisiana for both storms.
More to come...
