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

.DAY ONE...This afternoon and tonight...

A Flood Watch remains in effect through this evening for far
northwest Georgia where moderate to occasionally heavy rainfall could
lead to flooding of creeks, streams and rivers, as well as roadways
and low-lying areas.

Instability has increased over middle Georgia. Conditions are still
marginal for widespread severe storms this afternoon and evening,
however a few storms could be severe with damaging winds and may
produce a brief tornado. The threat will diminish after 10 PM as
storms move east and instability decreases.

.DAYS TWO THROUGH SEVEN...Saturday through Thursday...

Heavy rain will taper off Friday night from west to east, but runoff
from earlier rain could produce rises and continued flooding on area
creeks and rivers.

There is also a slight chance for snow flurries over far north
Georgia Saturday afternoon and Saturday evening, especially in
higher elevations. Little or no accumulation or impacts are expected
at this time.

.SPOTTER INFORMATION STATEMENT...

Spotter activation will not be needed through tonight.
