Area forecast discussion, Sep 30, 11:00 AM EDT, 1 hour 16 minutes before
AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE JACKSONVILLE FL
1100 AM EDT WED SEP 30 1998

THE TORNADO WATCH HAS EXPIRED AS OF 10 AM EDT...HOWEVER THERE ARE
STILL A FEW STRONG STORMS ABOUT AND WE CONTINUE TO GET REPORTS
OF FUNNEL CLOUDS ALONG THE SUWANNEE RIVER AREA. HELICITY VALUES
REMAIN HIGH...BUT INSTABILITY IS LACKING AT THIS TIME.

THE FLOOD WATCHES ALSO REMAIN IN EFFECT. AT THIS TIME WE ONLY HAVE
REPORTS OF MINOR FLOODING. UNLESS IT REALLY STARTS TO DUMP IN THE
NEXT FEW HOURS WE SHOULD BE OK IN THIS REGARD. WE'LL HAVE TO SEE
HOW THINGS WORK OUT AT MAX HEATING...BUT PRECIP WATER IS ONLY 1.67
INCHES OFF THE KJAX SOUNDING. THIS IS NOT VERY FAVORABLE FOR
WIDESPREAD HEAVY RAxIN...BUT LOCALIZED AMOUNTS COULD BE LARGE.
