CNTRL THROUGH E CNTRL LA.
VERY LITTLE MOVEMENT OF THE CONVECTIVE BAND IS EXPECTED DURING THE
NEXT FEW HOURS AND STORMS DEVELOPING WITHIN THE BAND WILL CONTINUE
TO TRAIN NEWD ALONG THE SAME PATH. THIS AND VERY MOIST PROFILES WITH
PRECIPITABLE WATERS IN EXCESS OF 2 INCHES WILL CONTINUE TO SUPPORT
VERY HEAVY RAIN IN THE CORRIDOR FROM ERN LA THROUGH WRN MS THIS
