This Hazardous Weather Outlook is for portions of North and Central Georgia.

.DAY ONE...This Afternoon and Tonight...

Some ongoing morning showers and thunderstorms that have been
training across portions of north Georgia have resulted in several
Flash Flood Warnings being issued. Some rainfall amounts near 3
inches have possibly fallen in northwest Georgia with an
additional 1 to 2 inches possible as well.

Otherwise scattered showers and thunderstorms are expected
to develop through the afternoon and evening across north and
central Georgia. Some storms could become strong and a few
isolated severe storms cannot be ruled out with the main threats
of strong to damaging winds, frequent lightning, and locally heavy
rainfall.

.DAYS TWO THROUGH SEVEN...Thursday through Tuesday...

Scattered to numerous thunderstorms in the afternoons and
evenings are expected each day through Thursday. As usual during
the summer, any storm will have the potential to become strong to
severe and be capable of producing gusty winds, frequent
lightning, and locally heavy rainfall.

Thunderstorm chances look to be confined mainly to central Georgia
and portions of north Georgia for Friday and then mainly far
south central Georgia for the weekend.
