CLIMATE SUMMARY...  
 
COLD FRONTS BROUGHT SIGNIFICANT RAINFALL TO THE AREA TUESDAY NIGHT  
AND WEDNESDAY...AND ALSO OVER THE WEEKEND...AND PROVIDED SOME NEEDED  
RELIEF TO THE DROUGHT CONDITIONS IN CENTRAL ALABAMA. AS A RESULT,  
MOST LOCATIONS HAVE RETURNED TO NEAR NORMAL RAINFALL FOR THE YEAR.  
CUMULATIVE RAINFALL DURING THE PAST WEEK AVERAGED THREE TO FIVE  
INCHES OVER MUCH OF CENTRAL ALABAMA...ALTHOUGH TOTALS OF ONE TO  
THREE INCHES WERE MORE PREVALENT IN THE EXTREME SOUTHEAST SECTIONS.  
THIS HAS SIGNFICANTLY IMPROVED DROUGHT CONDITIONS OVER MUCH OF  
CENTRAL ALABAMA AT LEAST TEMPORARILY.  
 
SOME PRECIPITATION AMOUNTS (INCHES) FOR CENTRAL ALABAMA FROM JANUARY  
1ST THROUGH FEBRUARY 7TH...  
 
BIRMINGHAM 5.44

AGRICULTURAL IMPACTS...  
 
THERE ARE NOT ANY KNOWN WIDESPREAD ACRIGULTURAL PROBLEMS AT THIS  
TIME DUE TO THE CURRENT DROUGHT CONDITIONS. HOWEVER IF THE CURRENT  
DROUGHT CONDITIONS PERSIST OR WORSEN AGRICULTURAL CONCERNS COULD  
ARISE AS WE HEAD THROUGH THE WINTER AND SPRING SEASONS.  
 
FIRE DANGER IMPACTS...  
 
THE FIRE DANGER RISK IS GENERALLY LOW ACROSS CENTRAL ALABAMA AT THIS  
TIME WITH KEETCH-BYRAM DROUGHT INDICES (KBDI) CURRENTLY RUNNING AT  
100 OR BELOW ACROSS MOST OF THE AREA...ALTHOUGH VALUES TO AROUND 200  
ARE STILL INDICATED IN SOME OF THE EXTREME SOUTHERN AREAS. VALUES  
ABOVE 500 INDICATE A SEVERE FIRE DANGER.  
 
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.  
 
HYDROLOGIC SUMMARY AND OUTLOOK...  
 
THE LATEST USGS STREAM GAUGE DATA INDICATES THAT STREAM FLOWS ARE  
CURRENTLY RUNNING ABOVE NORMAL ACROSS MUCH OF CENTRAL ALABAMA  
FOLLOWING THE RECENT HEAVY RAINFALL. PERIODIC RAINFALL WILL BE  
NEEDED FOR STREAM FLOWS TO REMAIN NEAR NORMAL OR ABOVE NORMAL LEVELS  
AS WE CONTINUE THROUGH THE WINTER SEASON INTO SPRING.  
 
MOST OF THE MAJOR RESERVOIR POOL LEVELS ARE NEAR THEIR NORMAL WINTER  
POOL LEVELS AND HAVE REMAINED FAIRLY STEADY OR RISEN SLIGHTLY DURING  
THE PAST WEEK. A FEW RESERVOIRS HAVE BEEN RAISED A LITTLE ABOVE  
THEIR NORMAL WINTER POOL LEVELS BY OPERATORS TO FACILITATE FILLING  
THEM LATER THIS SPRING SHOULD THE DROUGHT PERSIST OR WORSEN. LISTED  
BELOW ARE CURRENT LEVELS FOR SOME OF THE MAJOR RESERVOIRS ACROSS  
CENTRAL ALABAMA AND THOSE FROM FEBRUARY 1ST.  
 
RESERVOIR LEVEL FOR 02/08/18 LEVEL FOR 02/01/18  
 
WEISS 561.0 560.5  
NEELY HENRY 506.9 506.9  
LOGAN MARTIN 462.1 461.7  
LAY 395.7 395.8  
MITCHELL 311.7 311.8  
JORDAN 251.6 251.6  
R.L. HARRIS 786.8 786.8  
MARTIN 483.5 482.9  
SMITH 498.4 496.1  
BANKHEAD 254.4 254.9  
HOLT 186.2 186.6  
 
SOCIAL IMPACTS...  
 
RESERVOIR LEVELS ARE NEAR THEIR WINTER POOL LEVELS IN MOST  
LOCATIONS...ALTHOUGH SOME HAVE RISEN A LITTLE FOLLOWING THE RECENT  
HEAVY RAINFALL. THERE ARE NO KNOWN MANDATORY WATER RESTRICTIONS  
CURRENTLY IN EFFECT. HOWEVER NORMAL WATER CONSERVATION METHODS ARE  
ENCOURAGED TO BE FOLLOWED IN THE EVENT THAT THE DROUGHT CONDITIONS  
PERSIST OR WORSEN DURING THE NEXT FEW WEEKDS.  
 
PRECIPITATION AND TEMPERATURE OUTLOOK...  
 
A HIGH PRESSURE SYSTEM OVER THE AREA IS BRINGING DRY WEATHER TO THE  
AREA TODAY...AND THIS SHOULD CONTINUE INTO FRIDAY. HOWEVER THE DRY  
WEATHER WILL BE SHORT-LIVED AS A MOIST SOUTHWESTERLY FLOW PATTERN IS  
FORECAST TO DEVELOP BY SATURDAY AND PERSIST INTO THE FIRST HALF OF  
NEXT WEEK. THIS WILL ALLOW FOR AN UNSETTLED WEATHER PATTERN WITH  
PERIODIC BOUTS OF RAINFALL ACROSS THE AREA FROM SATURDAY INTO MID  
WEEK NEXT WEEK. AT THIS TIME CUMULATIVE RAINFALL TOTALS OF TWO TO  
FOUR INCHES APPEAR LIKELY ACROSS MUCH OF CENTRAL ALABAMA BY NEXT  
THURSDAY.  
 
THE TWO WEEK OUTLOOK...FROM FEBRUARY 13TH THROUGH FEBRUARY  
21ST...CALLS FOR ABOVE NORMAL TEMPERATURES AND ABOVE NORMAL  
PRECIPITATION CHANCES TRANSITIONING TO BELOW NORMAL CHANCES.  
 
THE LONGER-RANGE OUTLOOK FOR THE REMAINDER OF FEBRUARY THROUGH APRIL  
IS FOR ABOVE NORMAL TEMPERATURES AND NEAR TO BELOW NORMAL  
PRECIPITATION.  
 
THE LATEST SEASONAL DROUGHT OUTLOOK THROUGH APRIL INDICATES THAT  
DROUGHT CONDITIONS ARE EXPECTED TO PERSIST ACROSS MUCH OF CENTRAL  
ALABAMA.  
 
UPDATE STATEMENT...  
 
THE MEXT STATEMENT WILL BE ISSUED AROUND THURSDAY FEBRUARY 15TH.
