.DISCUSSION...

Hurricane Helene has emerged into the Gulf of Mexico. She will
continue to move northward today and should make landfall along the
Florida Big Bend coast this evening. After landfall, the remnants of
Helene will move northward very quickly across the state overnight
and then take a NW jog into the TN valley on Friday. Some weakening
is expected after Helene moves inland, but with such quick movement
northward, damaging wind gusts from the storm will be more likely
further inland.
