Georgia Drought Update – May 3 2012

As anticipated, the small area of drought improvement in Northeast Georgia last week, is all but gone this week.

Since my last drought update on April 23 2012, it has been quite dry across much of Georgia. Abnormally Dry conditions continue to cover much of North Georgia, with Moderate drought conditions beginning to creep back in.
Severe Drought conditions continue to hold in areas of Southeast and North central Georgia, ever so slowly creeping towards North Georgia.
Extreme Drought conditions now cover a large area of Georgia from North Central to the state line with Florida.
Exceptional Drought conditions, the highest level of drought, has expanded in Central Georgia while other areas experiencing Exceptional Drought in south Georgia remaining unchanged since my last report.

The overall breakdown on drought conditions in Georgia as of May 1 2012 are as follows:

The entire state of Georgia is experiencing Abnormally Dry conditions, 96.50 %, except for a small area mentioned in North GA.
Moderate Drought covers 88.56 % of the state.
Severe Drought covers 84.28 % of the state.
Extreme Drought covers 70.94 % of the state.
Exceptional Drought covers 25.85 % of the state.

Here’s a graphic showing Drought conditions from April 17 thru May 1 2012

To show how dry it has been in Georgia and much of the southeast, here’s a graphic showing how much rain these areas have seen since the beginning of 2012. Notice the areas of Red in Georgia and Florida; these areas have only received 50 to 25 percent of normal rainfall since the start of the year.

To put the above in perspective, here’s a graphic showing departure from normal rainfall from May of 2011 thru April 2012. Much of Georgia is showing a deficit of 8 inches with areas in southwest Georgia pushing the 20 inch below normal mark.

Here’s a look at precipitation or lack of for select areas around the state of Georgia through May 2 2012.

This first table shows total rainfall for the last 365 days:


ATLANTA 32.33 49.74 -17.41 65%
ATHENS 29.11 46.39 -17.28 63%
COLUMBUS 38.40 46.81 -8.41 82%
MACON 28.91 45.75 -16.84 63%

This table shows total rainfall fro the last 90 days:


ATLANTA 7.53 12.91 -5.38 58%
ATHENS 5.89 12.12 -6.23 49%
COLUMBUS 7.88 13.52 -5.64 58%
MACON 5.30 11.87 -6.57 45%

At this time it’s looking like drought conditions will continue to expand and intensify for Georgia. I expect the same can be said for much of the southeast as I see no reason at this time not to think this. It appears a summer type pattern has set up early this year with scattered hit and miss showers and storms, and as earlier this week in Georgia, above average and record breaking high temperatures. Showers and storms of this type offer little relief for drought stricken areas, and what little rain may fall is quickly absorbed in the dry earth and back into the atmosphere.

Here’s a look at Drought conditions across the rest of the U.S.:

A couple things to check on your Car for Winter driving


Make sure your antifreeze is still able to protect your radiator and engine from freezing. A few dollars now will save thousands later. To self check you will need a hydrometer [antifreeze/coolant tester] to check the concentration of ethylene glycol antifreeze in the coolant, or a refractometer if you use propylene glycol antifreeze/coolant. A refractometer works with either type of antifreeze. A 50/50 mixture of antifreeze and water for adequate freezing, boiling and corrosion protection is a must for long engine life. A 50/50 mixture of ethylene glycol antifreeze should protect down to a temperature of -34°F, and a 50/50 mix of propylene glycol antifreeze down to -26°F.

Tire pressure

You also need to check your ‘tire pressure’. You should check your tire pressure once a month regardless of the season. During cooler / colder months of the year, air pressure will drop. This will cause excessive wear and heating of the tire due to more rubber being in contact with the road surface. This also leads to premature blow outs which may cause you to loose control when driving at higher speeds. The same is true during summer / warmer months of the year. During warmer months, air will expand causing the tire to become over-inflated. As you drive the pressure will build to more than the tire is rated and to handle. Proper tire inflation is a must for safe driving. It also saves you money buy using less gas, and your tires will last longer.

I hope these tips will help you and your car!

Georgia Drought Update August 18 2011

In the last Drought update on August 11 I mentioned that I had some decent rains as well as other spots around the local area. In that post I also mentioned that the rains were not reflected in that weekly report. Well, It really had no effect on drought conditions in the local area. Why ? Because we have had little in the way of rain since that time, on August 8th. The last time it rained here at the homestead was August 11th. On that day I recorded 0.29 inches.

While we have enjoyed some cooler temperatures and lower humidity in the last week, we have seen no rain save a few short lived pop-up isolated showers. Some of those brought some good rain to the northern and eastern part of Harris county.
So not much has changed from last week to this in the local area. Other areas of the state have seen marked improvement. Here is the graph showing last week versus this week.

Here are Drought percentages covering the whole state.

And here is the rest of the Southeast.

Here is the Palmer Drought Severity Index showing how much rain is needed to bring conditions back to somewhat normal.

I wont bore you with the other graphs as they are not much different than last week either.
