.SYNOPSIS...
Hurricane Helene has made landfall in the Florida Big Bend and will
quickly move northwest of our local waters overnight through
Friday morning, with tropical storm conditions expected to
continue through around sunrise on Friday. Winds and seas will
gradually subside on Friday afternoon, as Helene races northward
across Georgia and enters the Tennessee Valley. Otherwise, a
stalled frontal boundary over the Florida peninsula on Saturday
will begin to slowly lift northward towards the northeast Florida
waters early next week, accompanied by scattered showers and
thunderstorms. A cold front will then enter the southeastern
states towards midweek, possibly pushing across the Georgia waters
by Wednesday night.
