Before I get to the current drought situation in Georgia and the southeast, I would first like to mention the possibility of some good rain heading in this coming week. Without going into great detail of the approaching system, areas in the Southeast may see some high accumulation rates beginning Today [6/8/2012] through Thursday of next week. Some of the higher rain totals predicted will occur along the Gulf coast, seeing possibly as much as 10 inches of rain.
Here’s the 5 day outlook from the Hydrometeorological Prediction Center [HPC] valid from 8 Pm Thursday thru 5 PM Tuesday evening June 15 2012. There is the potential some areas will have flooding issues through next week.
The NWS Peachtree City, GA mentions precipitation approaching 4 inches in areas of West Central Georgia. The NWS Huntsville, AL is in agreement mentioning 3 to 4 inches possible for northern Alabama areas.
Drought Impacts from Tropical Storm Beryl
In my last Drought update on May 25, 2012, I mentioned the possibility of a Tropical System of some type impacting the areas of Georgia and Florida. Other areas in the Southeast also saw welcomed rains from that system known as Tropical Storm Beryl.
from the Drought Monitor Archives-Contiguous U.S. MAy 29 2012 – Tropical Storm Beryl formed on May 25 about 300 miles east of Charleston, South Carolina, and moved southwestward. Beryl made landfall just after midnight on Memorial Day, May 28, near Jacksonville Beach, Florida, then passed near Valdosta, Georgia, before turning toward the north and northeast. Before accelerating away from the coastal Carolinas on May 30, Beryl provided much-needed rain to drought-affected areas from Florida to the Mid-Atlantic coastal plain.
Here’s a Radar estimated rainfall amount from Moody Air Force Base, GA. Radar Precip Est From 1105 AM EDT Sun May 27 2012 to 0242 AM EDT Tue May 29 2012
While the rain from Beryl did help the drought situation in areas of Southeast Georgia, North Florida, and other areas in South and North Carolina, it did little for North Central, Central and Southwest Georgia. Here’s a graphic showing drought conditions in Georgia. On the left: Drought conditions on May 22 before Beryl. On the right: Current drought conditions as of June 5 2012 after Beryl.
Here’s a graphic showing the Drought conditions in the Southeast for the same time period. Notice North Carolina and Upstate South Carolina. On the left: Drought conditions on May 22 before Beryl. On the right: Current drought conditions as of June 5 2012 after Beryl.
Here’s a graphic showing Rain amounts for the last 14 days ending June 7. Notice the area along the east coast down through Florida, where impacts from Tropical Storms Beryl were seen the most.
Here’s what drought conditions look like for the remainder of the U.S. at this time.
And finally, here’s how much precipitation would be required to end drought conditions across the U.S. in 3 months. [NOTE: The end of a drought is defined by a PHDI value of -0.5.]
