#Georgia #Drought Update – Conditions Worsen – November 21 2012

Don’t let the cooler weather fool you. Lack of rain in Georgia increases drought coverage and intensity.

Since my last Drought Update November 2 2012 Georgia has remained dry. Here at the homestead in Cataula, GA. I’ve recorded 0.68 inches of rain since November 1st to date. Since October 1st I have recorded 1.98 inches of rain to date. On October 30th 2012 80.77% of Georgia was experiencing some form of drought. As of November 20th 2012 drought coverage has spread and now 93.07% of Georgia is experiencing drought conditions. Areas of Georgia currently without drought are the Northwest and Southeast corners. Middle and West Central Georgia are the hardest hit with drought and currently experiencing ‘Extreme to Exceptional’ drought conditions.
