DISCUSSION
IN THE SHORT TERM, THUNDERSTORM NEAR BREAUX BRIDGE CONTINUES TO MOVE
SLOWLY EAST TOWARD THE HAZMAT AREA, WITH NEAREST LIGHTNING STRIKES ABOUT
5 MILES TO THE WEST AT THIS TIME. IT IS NOT CERTAIN IF RAINFALL WILL
REACH THE HAZMAT AREA, AS THE THUNDERSTORM DOES SEEM TO BE WEAKENING. IT
ALSO APPEARS THAT OUTFLOW WILL BE PUSHED TOWARD THE HAZMAT AREA, SO A
WIND SHIFT AND INCREASE IN EASTERLY WINDS IS POSSIBLE.
ISOLATED SHOWERS AND/OR THUNDERSTORMS WILL BE POSSIBLE THE REST OF THE
AFTERNOON.
