DROUGHT INFORMATION STATEMENT  
NATIONAL WEATHER SERVICE BALTIMORE MD/WASHINGTON DC  
910 AM EDT THU OCT 31 2019  
 
...DROUGHT ENDS AS DRY LATE SUMMER GIVES WAY TO ONE OF THE WETTEST  
SECOND HALF OF OCTOBERS ON RECORD...  
 
SYNOPSIS...  
WITH ONE SMALL EXCEPTION, DROUGHT CONDITIONS HAVE ABATED ACROSS  
THE REGION FOLLOWING AN EXCEEDINGLY WET SECOND HALF OF OCTOBER.  
 
THE UNITED STATES DROUGHT MONITOR (USDM) VALID ON TUESDAY,  
OCTOBER 29TH, 2019, AND RELEASED ON THURSDAY, OCTOBER 31ST,  
INDICATES DROUGHT CONDITIONS HAD AGAIN IMPROVED. THE ONLY  
REMAINING AREA OF MODERATE DROUGHT (D1) IS NOW IN SOUTHWESTERN  
LOUDOUN COUNTY, VIRGINIA; AND NORTHERN FAUQUIER COUNTY, VIRGINIA,  
AND THIS AREA SAW HALF AN INCH OF RAIN ON OCTOBER 30TH WITH MORE  
ON THE WAY TO END THE MONTH, SO FURTHER IMPROVEMENT IS LIKELY.  
 
MUCH OF THE REMAINDER OF THE AREA IS STILL INDICATED AS  
ABNORMALLY DRY (D0) DUE TO LINGERING RAINFALL DEFICITS FROM AUGUST  
AND SEPTEMBER...BUT CONDITIONS ARE NOW DEFINITELY NO LONGER DRY.  
 
DURING THE TWO WEEK PERIOD FROM OCTOBER 16TH TO OCTOBER 30TH, THE  
ENTIRE AREA RECEIVED BETWEEN THREE AND SIX INCHES OF RAIN. NORMAL  
RAINFALL FOR OCTOBER IS GENERALLY BETWEEN 2.5 AND 4.0 INCHES, SO  
EVERYONE HAS RECEIVED ABOVE NORMAL RAINFALL FOR THE MONTH --  
ALMOST ALL OF IT FALLING IN THE SECOND HALF OF THE MONTH.  
 
IN FACT, THE TOTAL AT BWI FROM OCTOBER 16-30 IS 4.98 INCHES, WHICH  
BY ITSELF WOULD RANK AS THE SIXTH WETTEST SECOND HALF OF OCTOBER  
ON RECORD (DATING BACK TO 1870). MORE RAIN ON OCTOBER 31ST WILL  
ADD TO THAT TOTAL. AT DCA, THE TOTAL FROM OCTOBER 16-30 IS 5.27  
INCHES, WHICH BY ITSELF WOULD RANK AS THE FOURTH WETTEST SECOND  
HALF OF OCTOBER ON RECORD (DATING BACK TO 1871). THIS WILL BE THE  
WETTEST OCTOBER REGIONWIDE SINCE AT LEAST 2013.  
 
SUMMARY OF IMPACTS...  
IMPACTS ARE NOW ESSENTIALLY NEGLIGIBLE. SOIL MOISTURE,  
GROUNDWATER, AND STREAMFLOWS ARE ALL NEAR TO ABOVE NORMAL.  
 
DROUGHT MITIGATION ACTIONS...  
ON OCTOBER 11TH, THE GOVERNOR OF VIRGINIA DECLARED A DROUGHT  
WATCH FOR THE ENTIRE STATE DUE TO THE DRY CONDITIONS THAT EXISTED  
AT THE TIME. THIS STATUS IS BEING REASSESSED THIS WEEK. CONSULT  
THE STATE'S DEPARTMENT OF ENVIRONMENTAL QUALITY FOR FURTHER  
UPDATES ON THE STATE DROUGHT STATUS.  
 
AT THE TIME OF THIS STATEMENT (OCTOBER 24TH, 2019) THERE WERE NO  
OTHER DROUGHT DECLARATIONS BY THE STATES IN OUR SERVICE AREA.  
 
THERE ARE NO SPECIFIC BURN BANS IN PLACE WITHIN THE AREA AT THIS  
TIME. SEASONAL REGULATIONS REMAIN IN PLACE, AND OTHER LOCAL BURN  
BAN LAWS OR DECLARATIONS MAY APPLY. ALWAYS CONSULT WITH LOCAL  
OFFICIALS PRIOR TO ATTEMPTING AN OPEN BURN.  
 
LOCAL DROUGHT OUTLOOK...  
MORE RAIN IS FALLING AT THE TIME OF THIS STATEMENT (OCTOBER  
31ST). BEYOND THAT, A PATTERN CHANGE IS EXPECTED TO TURN US DRIER  
AGAIN FOR EARLY NOVEMBER, WITH ONLY A SMALL CHANCE FOR RAIN AROUND  
THE MIDDLE OF NEXT WEEK (NOVEMBER 5-7). THE OUTLOOK FROM THE  
CLIMATE PREDICTION CENTER FOR WEEK 2 (NOVEMBER 7-13) FAVORS NEAR  
NORMAL PRECIPITATION, WHILE THE OUTLOOK FROM THE CLIMATE  
PREDICTION CENTER FOR ALL OF NOVEMBER INDICATES EQUAL CHANCES OF  
ABOVE, BELOW, OR NEAR NORMAL PRECIPITATION.  
 
NEXT ISSUANCE DATE...  
THIS IS THE FINAL DROUGHT INFORMATION STATEMENT TO BE ISSUED FOR  
THIS EVENT. THE NEXT DROUGHT INFORMATION STATEMENT WILL BE ISSUED  
WHEN MODERATE DROUGHT (D1) IS RE-INTRODUCED INTO ANY PORTION OF  
OUR SERVICE AREA.
