THERE IS A MDT RISK OF SVR TSTMS FOR PTNS OF SRN AND ERN TX...
MUCH OF LA..EXTRM SRN AR..AND PTNS SWRN MS.  THE MDT RISK AREA IS
TO RGT OF LN FM CRP COT ERV TYR TXK GLH JAN BTR 50 SSW LFT.

SURROUNDING THE MDT RISK IS A SLGT RISK OF SVR TSTMS TO THE RT OF
A LN FM 20 SE CRP LRD DRT DFW HOT MEM MSL ANB AGS SAV JAX AQQ.
