Full Notification

The National Weather Service in Peachtree City has issued a Flash Flood Watch for Clayton County effective until 8 am on Saturday.  

Overview:

The ongoing threat for heavy rainfall and flash flooding will continue over the coming days. Since much of the area has received significant rainfall over the past several days, soils are saturated and many creeks and rivers are already at above-normal streamflow. Expected additional heavy rainfall will pose an enhanced flash flooding and river flooding threat.

Threats: 

    •    Heavy rainfall that would lead to flash flooding and flooding of creeks and rivers. 

    •    Additional rainfall amounts of 3 - 5 inches with isolated higher amounts of 6+ inches are possible through next Thursday.

Timing:

    •    Through Saturday: Widespread showers and thunderstorms can be expected, especially during the afternoon and overnight hours. As has been seen the past few days, the threat for slow-moving thunderstorms that set up over a specific area may lead to rainfall totals of 1 - 2 inches with localized higher amounts of 3+ inches.

    •    Sunday into next week: A developing tropical system will approach the area from the Gulf of Mexico bringing the threat for waves of additional heavy rainfall across the state during this time frame. Rainfall totals of 2 - 3 inches with localized higher amounts of 4+ inches.

Location:

    •    Through Saturday: The highest likelihood for the heaviest rainfall totals from tonight through Saturday will be across central Georgia into portions of north Georgia as indicated by the Flash Flood Watch area.

    •    Sunday into next week: Periods of heavy rainfall become more likely area wide as a developing tropical system approaches the Southeast. 

Impacts:

    •    Roads may become covered with water or washed out in some areas.

    •    Minor flooding of some creeks and rivers is likely with moderate flooding possible. (* Please keep in mind that the River Forecast Center forecast rainfall extends only 48 hours, so river and creek forecasts you may refer to now do not yet include forecast rainfall from the potential weekend tropical system.*)
