DROUGHT INFORMATION STATEMENT  
NATIONAL WEATHER SERVICE BALTIMORE MD/WASHINGTON DC  
845 AM EDT THU MAY 11 2017  
   
..RECENT RAINS END DROUGHT CONDITIONS ACROSS THE AREA
 
   
..FINAL DROUGHT STATEMENT
 
 
SYNOPSIS...  
AS OF MAY 9TH 2017, THE U.S. DROUGHT MONITOR INDICATES THAT ALL  
DROUGHT CONDITIONS HAVE BEEN ALLEVIATED AS A RESULT OF RECENT  
RAINS.  
 
SOME AREAS ARE STILL DESIGNATED AS ABNORMALLY DRY (D0) BUT THIS IS  
BASED ON LONG-TERM DEFICITS, WHICH ARE ALSO QUICKLY DISAPPEARING.  
 
SUMMARY OF IMPACTS...  
STATE AND LOCAL DECLARATIONS:  
THE EXISTING DROUGHT WARNING FOR THE CENTRAL REGION OF MARYLAND,  
DECLARED BY THE MARYLAND DEPARTMENT OF THE ENVIRONMENT (MDE); AND  
THE DROUGHT WATCH FOR THE NORTHERN PIEDMONT AND NORTHERN VIRGINIA  
REGIONS OF VIRGINIA, DECLARED BY THE VIRGINIA DEPARTMENT OF  
ENVIRONMENTAL QUALITY (DEQ), HAVE NOT YET BEEN REASSESSED SINCE  
CONDITIONS IMPROVED, AND SO ARE STILL IN PLACE AT THE TIME OF THIS  
STATEMENT. THOSE DECLARATIONS ARE REASSESSED PERIODICALLY. CONSULT  
LOCAL OFFICIALS FOR UPDATES.  
 
CLIMATE SUMMARY...  
RAINFALL OVER THE LAST WEEK HAS BEEN EXTREMELY PLENTIFUL, AND  
CONTINUES TO FALL AT THE TIME OF THIS STATEMENT. WIDESPREAD RAIN  
OF TWO TO FOUR INCHES HAS FALLEN IN THE PAST WEEK. SOME LOCATIONS  
JUST EAST OF THE BLUE RIDGE RECEIVED OVER FIVE INCHES. RAINFALL IN  
THE PAST 30 DAYS IS 3 TO 7 INCHES, WHICH IS NEAR TO WELL ABOVE  
NORMAL. RAIN IS NOW NEAR TO ABOVE NORMAL EVEN BACK TO 120 DAYS,  
AND THE 180 DAY RAINFALL IS AT LEAST 75 PERCENT OF NORMAL  
EVERYWHERE, A VAST IMPROVEMENT FROM RECENT WEEKS AND MONTHS.  
 
PRECIPITATION/TEMPERATURE OUTLOOK...  
AND MORE RAIN IS ON THE WAY. 1 TO 3 INCHES IS EXPECTED THROUGH  
THIS WEEKEND, WHICH WILL KNOCK OUT MOST OF THE REMAINING LONG-TERM  
DEFICITS. NEXT WEEK, THE WEATHER PATTERN COMPLETELY FLIPS,  
BRINGING EARLY SUMMER WEATHER BACK TO THE REGION ALONG WITH  
GENERALLY DRIER WEATHER FOR SEVERAL DAYS. A LONG DRY SPELL THOUGH  
DOES NOT APPEAR LIKELY.  
 
HYDROLOGIC SUMMARY AND OUTLOOK...  
STREAMFLOW HAS IMPROVED TO NEAR TO ABOVE NORMAL, AS HAS SOIL  
MOISTURE. GROUNDWATER IS ALL OVER THE MAP, BUT THAT ISN'T  
PARTICULARLY UNUSUAL AROUND THIS REGION. EVEN IN PLACES WHERE  
GROUNDWATER IS BELOW NORMAL, IT HAS IMPROVED FROM THE WORST OF THE  
WINTER AND EARLY SPRING.  
 
NEXT ISSUANCE DATE...  
WITH NO FURTHER MODERATE DROUGHT (D1) INDICATED IN THE AREA, THIS  
WILL BE THE FINAL ISSUANCE OF THIS PRODUCT FOR THIS EVENT.  
ISSUANCE OF THIS PRODUCT WILL RESUME WHEN MODERATE DROUGHT (D1)  
IS INDICATED IN WASHINGTON DC OR IN THE MIDDLE POTOMAC RIVER BASIN  
JUST UPSTREAM FROM WASHINGTON DC.
