More Rain on the Way to Add to Winter Rainfall Surplus
More Rain on the Way to Add to Winter Rainfall Surplus

We've had plenty of rain in metro Atlanta and north Georgia this winter.  Our rainfall totals are running close to 5 inches above the average so far for the months of December, January and February.  Check out the graphic that also shows plenty of rain for the past 7 days.  The map from the NWS office in Peachtree City shows much of the metro area getting 2 to 3 inches of rain last week.  The darker yellow color indicates 3-4 inches of rain.  Factor that in with the above average rainfall for the last 3 months, and you can see why there is a flood watch in effect for much of the area with this next round of rain moving our way.

See the map below that shows the counties highlighted in green that are in a Flood Watch from Monday morning until Tuesday evening.  The area in the watch runs from Carroll County to Douglas, Cobb, Fulton, Forsyth, Hall and Banks county south and eastward into central and south Georgia.  The heavier rain will be in central and south Georgia.  Metro Atlanta will see on average around 2 inches of rain through Tuesday.  Many rivers, creeks and streams are already swollen with the recent rain.  It won't take too much runoff to make these creeks and streams rise again.  Folks who live in flood prone areas need to keep an eye on rising water over the next couple of days.

This shows why the ground can't soak up much more moisture.  It's pretty saturated.  Here's a look at the rainfall for the past 3 months.

December-5.93" (2.03" above average)

January-4.90" (.70" above average)

February-5.97" so far (2.11' above average)

We've had almost 5 inches of additional rainfall for the past 3 months than average.  Any additional rain will cause runoff into creeks and streams.

The rain will move in from the southwest toward the northeast during the day Monday.  It will start off as light rain moving in during the afternoon off and on.  The heavier rain will be late Monday night into Tuesday morning.  After this moves out, we will be dry for a few days as much colder air arrives at the end of the week.
