Flash Flood Watch
Issued: 12:04 PM EST Feb. 20, 2019 – National Weather Service

... Flash Flood Watch in effect through Thursday evening...

The National Weather Service in Peachtree City has issued a

* Flash Flood Watch for portions of north central Georgia...
northeast Georgia... northwest Georgia and west central
Georgia... including the following areas... in north central
Georgia... Barrow... Clayton... Cobb... DeKalb... Douglas...
Fayette... Forsyth... Gwinnett... Hall... north Fulton and South
Fulton. In northeast Georgia... banks and Jackson. In northwest
Georgia... Carroll. In west central Georgia... Coweta and heard.

* Through Thursday evening

* soil conditions remain very saturated and river levels remain
high across the area. The potential for locally heavy rainfall
will increase tonight and last through Thursday evening.
Rainfall totals between 1" and 3" are likely, with locally
higher amounts possible. This amount of rainfall will produce
significant runoff and flooding of creeks and rivers. The watch
may have to be extended into Friday, or even the weekend, as
additional rainfall is expected during this time.


* Periods of heavy rain can overwhelm or clog storm drains and
ditches with debris and cause extensive street flooding and Road
ponding. This is especially true this time of year as fallen
leaves block or impede drainage systems. Take time ahead of the
rain to clear leaves and debris from these drainage systems. Due
to the extremely saturated soils, downed trees will be likely,
even with sub severe winds.

Precautionary/preparedness actions...

A Flash Flood Watch means that conditions may develop that lead
to flash flooding. Flash flooding is a very dangerous situation.

You should monitor later forecasts and be prepared to take action
should flash flood warnings be issued.
