SYNOPSIS...THE LATEST U.S. DROUGHT MONITOR INDICATES THAT DROUGHT  
CONDITIONS HAVE PERSISTED WITH EXPANDED ABNORMALLY DRY CONDITIONS  
ACROSS ALL BUT A PORTION OF SOUTHWEST ALABAMA INCLUDING PORTIONS OF  
SOUTHEAST DALLAS, SOUTHWEST LOWNDES, EASTERN CLARKE, MUCH OF MONROE,  
WESTERN CONECUH AND WEST-CENTRAL ESCAMBIA COUNTIES. MODERATE DROUGHT  
CONDITIONS HAVE ALSO EXPANDED TO INCLUDE MUCH OF NORTHWEST ALABAMA  
GENERALLY FROM NEAR TUSCALOOSA TO JUST WEST OF HUNTSVILLE. THIS AREA  
EXTENDS SOUTHEAST TO INCLUDE MUCH OF CULLMAN, JEFFERSON, BLOUNT AND  
ST. CLAIR COUNTIES AND ENCOMPASSES MUCH OF EASTERN ALABAMA FROM MUCH  
OF CALHOUN COUNTY AND THE SOUTHERN TWO-THIRDS OF CLEBURNE COUNTY  
SOUTH TO THE NORTHERN AND WESTERN HALF OF RUSSELL COUNTY WEST TO

PORTIONS OF FAR EASTERN MONTGOMERY COUNTY AND THE EASTERN HALF OF  
ELMORE COUNTY. ANOTHER AREA OF MODERATE DROUGHT INCLUDES MUCH OF  
MARENGO COUNTY WITH FAR NORTHERN CLARKE COUNTY. A THIRD AREA OF  
MODERATE DROUGHT INCLUDES MUCH OF GENEVA COUNTY, MUCH OF COFFEE

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...  
 
ONLY SOME SPOTTY GENERALLY LIGHT RAINFALL OCCURRED ACROSS THE AREA  
DURING THE PAST WEEK FROM ISOLATED TO SCATTERED SHOWERS AND  
THUNDERSTORMS. AREAS THAT RECEIVED RAINFALL WERE MOSTLY LIMITED TO  
THE NORTHERN AND WESTERN PORTIONS OF CENTRAL ALABAMA AND MOST OF  
THESE AREAS AVERAGED LESS THAN A HALF OF AN INCH. THIS DID LITTLE TO  
HELP ALLEVIATE THE DROUGHT CONDITIONS AND THE LATEST USGS GAUGE  
READINGS INDICATE THAT STREAM FLOWS ACROSS THE AREA HAVE CONTINUED  
TO DECLINE DUE TO THE SPARSE RAINFALL WITH MOST AGAIN AT BELOW  
NORMAL FLOWS FOR THIS TIME OF THE YEAR.

ANNISTON 19.26  
TUSCALOOSA 20.60

AGRICULTURAL IMPACTS...  
 
THE UNITED STATES DEPARTMENT OF AGRICULTURE (USDA) REPORTS THAT  
RAINFALL HAS BEEN ADEQUATE FOR THE TIME OF YEAR AND PASTURES ARE  
RECOVERING SOMEWHAT ALTHOUGH WARM SEASON PASTURES HAVE STRUGGLED  
SOME DUE TO THE COOL WEATHER IN MARCH. THE WHEAT CROP IS REPORTED  
TO BE IN GOOD SHAPE AND POTATOES HAVE BEEN PLANTED. FARMERS HAVE  
TAKEN ADVANTAGE OF THE RECENT DRY WEATHER WHICH HAS BEEN FAVORABLE  
FOR PLANTING TO BEGIN. HOWEVER...WITH THE PLANTING BEING COMPLETED  
IN MANY AREAS RAINFALL IS NOW NEEDED TO GET THE SEEDS UP.  
 
FIRE DANGER IMPACTS...  
 
THE FIRE DANGER RISK REMAINS RELATIVELY LOW BUT HAS INCREASED  
SOMEWHAT ACROSS CENTRAL ALABAMA WITH KEETCH-BYRAM DROUGHT INDICES  
(KBDI) GENERALLY RANGING FROM 100 TO 300 WITH SOME VALUES NOW ABOVE  
300 IN SOME OF THE NORTHWEST SECTIONS. VALUES ABOVE 500 INDICATE A  
SEVERE FIRE DANGER.  
 
BASED ON INFORMATION RECEIVED FROM THE ALABAMA FORESTRY COMMISSION,  
THERE ARE NOW INDICATIONS THAT MANY PINE TREES ARE DYING DUE TO  
INFESTATION FROM PINE BEETLES AND OTHER PESTS. 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 IN EFFECT, 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.  
 
HYDROLOGIC SUMMARY AND OUTLOOK...  
 
THE LATEST USGS STREAM GAUGE DATA INDICATES THAT STREAM FLOWS HAVE  
DECLINED TO BELOW NORMAL ACROSS MUCH OF CENTRAL ALABAMA FOR THIS  
TIME OF YEAR AS A LACK OF RECENT RAINFALL IN ONCE AGAIN BEING FELT.  
PERIODIC RAINFALL WILL BE NEEDED FOR STREAM FLOWS TO RETURN TO NEAR  
NORMAL OR ABOVE NORMAL LEVELS AS WE CONTINUE THROUGH THE SPRING  
SEASON.  
 
MOST OF THE MAJOR RESERVOIR POOL LEVELS HAVE EITHER REACHED OR ARE  
NEAR THEIR NORMAL SUMMER FULL POOL LEVELS. LISTED BELOW ARE CURRENT  
LEVELS FOR SOME OF THE MAJOR RESERVOIRS ACROSS CENTRAL ALABAMA AND  
THOSE FROM APRIL 13TH.  
 
RESERVOIR LEVEL FOR 04/20/17 LEVEL FOR 04/13/17  
 
WEISS 563.9 563.7  
NEELY HENRY 507.6 507.4  
LOGAN MARTIN 464.8 464.7  
LAY 395.7 395.8  
MITCHELL 311.8 312.0  
JORDAN 251.4 251.5  
R.L. HARRIS 792.9 792.6  
MARTIN 489.9 488.9  
SMITH 509.9 509.7  
BANKHEAD 254.8 254.5  
HOLT 186.5 186.5  
 
SOCIAL IMPACTS...  
 
RESERVOIR LEVELS ARE NEARING OR HAVE REACHED THEIR SUMMER POOL  
LEVELS AS RESERVOIR OPERATORS CONTINUE TO GRADUALLY RAISE THEM.  
ALTHOUGH SOME MOSTLY VOLUNTARY WATER RESTRICTIONS ARE STILL IN  
EFFECT MANY WATER RESTRICTIONS HAVE BEEN LIFTED BY LOCAL WATER  
BOARDS AND OPERATIONS HAVE RETURNED TO NORMAL.  
 
PRECIPITATION AND TEMPERATURE OUTLOOK...  
 
AN EARLY SUMMER-LIKE PATTERN WILL CONTINUE ACROSS MUCH OF THE STATE  
TODAY AND TOMORROW WITH A FEW MAINLY AFTERNOON SHOWERS AND  
THUNDERSTORMS POSSIBLE. RAIN CHANCES WILL INCREASE DURING THE DAY  
SATURDAY AS A STORM SYSTEM APPROACHES. RAINFALL POTENTIAL WILL BE  
BEST NORTHWEST WITH AMOUNTS JUST OVER THREE QUARTERS OF AN INCH  
POSSIBLE. THE REMAINDER OF THE AREA WILL HAVE THE POTENTIAL FOR  
AMOUNTS BETWEEN A TENTH AND A HALF OF AN INCH OF RAIN GENERALLY.  
AFTER SATURDAY, NO APPRECIABLE CHANCES OF RAIN ARE EXPECTED THROUGH  
MIDWEEK NEXT WEEK.  
 
OVER THE NEXT MONTH THE OUTLOOK CALLS FOR EQUAL CHANCES FOR  
PRECIPITATION ACROSS MUCH OF THE STATE WITH ABOVE AVERAGE  
TEMPERATURES LIKELY ACROSS THE STATE.  
 
THE SEASONAL OUTLOOK IS SIMILAR TO THE MONTHLY OUTLOOK WITH EQUAL  
CHANCES FOR PRECIPITATION ACROSS MUCH OF THE STATE WITH ABOVE  
AVERAGE TEMPERATURES LIKELY ACROSS THE STATE.  
 
UPDATE STATEMENT...  
 
THE NEXT STATEMENT WILL BE ISSUED AROUND THURSDAY APRIL 27TH.
