.. DROUGHT CONDITIONS DIMINISH IN CENTRAL ALABAMA
 
 
SYNOPSIS...THE LATEST U.S. DROUGHT MONITOR INDICATES THAT THE  
DROUGHT CONDITIONS THAT HAVE PERSISTED ACROSS CENTRAL ALABAMA HAVE  
IMPROVED. MODERATE DROUGHT IS NOW FOUND ONLY IN THE EXTREME NORTHERN  
PORTION OF TUSCALOOSA COUNTY NORTHWARD ACROSS EXTREME SOUTHERN  
FAYETTE COUNTY. ELSEWHERE ACROSS CENTRAL ALABAMA NEAR NORMAL OR  
ABNORMALLY DRY CONDITIONS ARE NOW FOUND.  
 
THE DROUGHT MONITOR CLASSIFIES DROUGHT WITHIN ONE OF THESE FIVE  
CATEGORIES:  
 
D0...ABNORMALLY DRY  
D1...MODERATE DROUGHT  
D2...SEVERE DROUGHT  
D3...EXTREME DROUGHT  
D4...EXCEPTIONAL DROUGHT  
 
CLIMATE SUMMARY...  
 
BENEFICIAL RAINFALL OCCURRED DURING THE PAST SEVERAL DAYS IN  
ASSOCIATION WITH AN UPPER TROUGH THAT DEVELOPED ACROSS THE EASTERN  
HALF OF THE UNITED STATES. RAINFALL TOTALS ACROSS CENTRAL ALABAMA  
DURING THE PAST WEEK HAVE AVERAGED FROM TWO TO FIVE INCHES ACROSS  
MUCH OF THE NORTHWEST HALF...AND FIVE TO TEN INCHES ACROSS THE  
SOUTHEASTERN SECTIONS. THIS HAS GREATLY ALLEVIATED THE DROUGHT  
CONDITIONS THAT HAVE PLAGUED THE AREA DURING THE PAST SEVERAL  
MONTHS...WITH MOST STREAM FLOWS IN THE AREA CURRENTLY ABOVE NORMAL  
FOR THE TIME OF YEAR.  
 
SOME PRECIPITATION AMOUNTS (INCHES) FOR CENTRAL ALABAMA FROM JANUARY  
1ST THROUGH MAY 24TH...  
 
BIRMINGHAM 27.42  
MONTGOMERY 33.46  
ANNISTON 25.64  
TUSCALOOSA 25.87  
CALERA 26.47  
TROY 32.30  
 
NORMAL PRECIPITATION EXPECTED (INCHES)AND DEPARTURE FROM NORMAL  
(INCHES) JANUARY 1ST THROUGH MAY 24TH...  
 
BIRMINGHAM 22.89 +4.53  
MONTGOMERY 22.67 +10.79  
ANNISTON 22.03 +3.62  
TUSCALOOSA 22.50 +3.37  
CALERA 22.84 +3.63  
TROY 21.51 +10.79  
 
AGRICULTURAL IMPACTS...  
 
THE UNITED STATES DEPARTMENT OF AGRICULTURE (USDA) REPORTS THAT  
PLANTING OF SPRINGS CROPS IS IN FULL PROGRESS. RAINFALL HAS HELPED  
IMPROVE PASTURES ACROSS THE AREA AND AIDED MANY OF THE CROPS THAT  
HAVE BEEN PLANTED. THE HARVESTING OF PEACHES AND STRAWBERRIES HAS  
BEGUN IN SOME AREAS. SUMMER VEGETABLE CROPS ARE ALSO BEING PLANTED  
IN MANY AREAS. PERIODIC RAINFALL WILL BE NEEDED TO MAINTAIN THE  
CROPS. IN GENERAL THE MAJORITY OF CATTLE AND CROPS ARE REPORTED TO  
BE IN FAIR OR BETTER CONDITION.  
 
FIRE DANGER IMPACTS...  
 
THE FIRE DANGER RISK HAS CHANGED LITTLE ACROSS CENTRAL ALABAMA WITH  
KEETCH-BYRAM DROUGHT INDICES (KBDI) REMAINING FAIRLY CONSTANT.  
VALUES ARE CURRENTLY RANGING FROM 100 TO 400 WITH ISOLATED VALUES  
ABOVE 400. VALUES ABOVE 500 INDICATE A SEVERE FIRE DANGER.  
 
BASED ON INFORMATION RECEIVED FROM THE ALABAMA FORESTRY COMMISSION,  
MANY HARDWOODS AND PINE TREES HAVE DIED DUE TO INFESTATION FROM PINE  
BEETLES AND OTHER PESTS. THIS IS A DIRECT RESULT OF THE DROUGHT  
SINCE IT HAS WEAKENED MANY TREES MAKING THEM MORE SUSCEPTIBLE TO  
INSECTS AND DISEASES. ACCORDING TO FORESTRY OFFICIALS, THERE COULD  
BE SIGNIFICANT LOSSES BUT THE EXACT ECONOMIC IMPACTS ARE NOT KNOWN  
AT THIS TIME. DESPITE THE FACT THAT THERE ARE CURRENTLY NO BURN BANS  
ISSUED BY THE ALABAMA FORESTRY COMMISSION, THE STATE FORESTER  
CONTINUES TO URGE PEOPLE THAT ARE DOING ANY OUTSIDE BURNING TO  
FOLLOW SAFETY PRECAUTIONS SUCH AS NOT LEAVING ANY FIRE UNATTENDED  
AND HAVING THE PROPER EQUIPMENT AND PERSONNEL TO CONTROL THE FIRE.  
SUMMER BURNING RESTRICTIONS FOR NON-AGRICULTURAL BURNS HAVE BEEN  
ISSUED BY THE ALABAMA DEPARTMENT OF ENVIRONMENTAL MANAGEMENT FROM  
MAY THROUGH OCTOBER FOR THE CENTRAL ALABAMA COUNTIES OF ETOWAH,  
JEFFERSON, MONTGOMERY, RUSSELL, SHELBY AND TALLADEGA.  
 
HYDROLOGIC SUMMARY AND OUTLOOK...  
 
THE LATEST USGS STREAM GAUGE DATA INDICATES THAT STREAM FLOWS HAVE  
RETURNED TO ABOVE NORMAL ACROSS MUCH OF CENTRAL ALABAMA FOLLOWING  
RAINFALL DURING THE PAST WEEK. PERIODIC RAINFALL WILL BE NEEDED FOR  
STREAM FLOWS TO REMAIN AT NEAR NORMAL OR ABOVE NORMAL LEVELS AS WE  
CONTINUE THROUGH THE SPRING SEASON INTO SUMMER.  
 
MOST OF THE MAJOR RESERVOIR POOL LEVELS ARE NEAR THEIR NORMAL SUMMER  
FULL POOL LEVELS AND HAVE REMAINED FAIRLY STEADY DURING THE PAST  
WEEK. LISTED BELOW ARE CURRENT LEVELS FOR SOME OF THE MAJOR  
RESERVOIRS ACROSS CENTRAL ALABAMA AND THOSE FROM MAY 18TH.  
 
RESERVOIR LEVEL FOR 05/25/17 LEVEL FOR 05/18/17  
 
WEISS 563.7 563.8  
NEELY HENRY 507.4 507.9  
LOGAN MARTIN 464.8 464.9  
LAY 395.3 395.9  
MITCHELL 311.7 311.9  
JORDAN 251.3 251.3  
R.L. HARRIS 793.0 793.0  
MARTIN 489.5 489.6  
SMITH 509.9 510.0  
BANKHEAD 254.6 254.8  
HOLT 186.1 186.6  
 
SOCIAL IMPACTS...  
 
RESERVOIR LEVELS ARE NEAR THEIR FULL SUMMER POOL LEVELS AS A RESULT  
OF OUR SPRING RAINFALL. ALTHOUGH A FEW MOSTLY VOLUNTARY WATER  
RESTRICTIONS ARE STILL IN EFFECT MOST WATER RESTRICTIONS HAVE BEEN  
LIFTED BY LOCAL WATER BOARDS AND OPERATIONS HAVE RETURNED TO NORMAL.  
 
PRECIPITATION AND TEMPERATURE OUTLOOK...  
 
DRIER AIR HAS OVERSPREAD CENTRAL ALABAMA TODAY AND SHOULD PREVAIL  
ACROSS THE AREA INTO SATURDAY. HOWEVER...BY SATURDAY NIGHT AND  
SUNDAY ENOUGH MOISTURE WILL RETURN TO THE AREA TO BRING A CHANCE OF  
SHOWERS AND THUNDERSTORMS BACK TO THE AREA. CHANCES FOR RAIN ARE  
EXPECTED TO INCREASE AS WE MOVE INTO SUNDAY NIGHT AND MONDAY AS  
ANOTHER COLD FRONT MOVES INTO THE AREA. SOME CHANCE FOR ADDITIONAL  
RAIN WILL LINGER ALONG AND BEHIND THE FRONT FOR TUESDAY INTO  
WEDNESDAY. CUMULATIVE RAINFALL TOTALS THROUGH NEXT WEDNESDAY ARE  
EXPECTED TO AVERAGE FROM ONE TO ONE AND A HALF INCHES IN THE  
NORTHERN SECTIONS TO LESS THAN AN INCH IN THE SOUTHEAST.  
 
THE TWO WEEK OUTLOOK...FROM MAY 30TH THROUGH JUNE 7TH...CALLS FOR  
BELOW NORMAL TEMPERATURES TRANSITIONING TO NEAR NORMAL TEMPERATURES  
AND ABOVE NORMAL PRECIPITATION CHANCES.  
 
THE LONGER-RANGE OUTLOOK FOR JUNE THROUGH AUGUST IS FOR ABOVE NORMAL  
TEMPERATURES AND EQUAL CHANCES FOR ABOVE NORMAL... NEAR NORMAL OR  
BELOW NORMAL PRECIPITATION.  
 
THE LATEST SEASONAL DROUGHT OUTLOOK THROUGH AUGUST INDICATES THAT  
DROUGHT CONDITIONS ARE EXPECTED TO IMPROVE WITH DROUGHT REMOVAL  
EXPECTED IN AREAS CURRENTLY EXPERIENCING THESE CONDITIONS.  
 
UPDATE STATEMENT...  
 
THE NEXT STATEMENT WILL BE ISSUED AROUND THURSDAY JUNE 1ST.
