DROUGHT INFORMATION STATEMENT
NATIONAL WEATHER SERVICE CARIBOU ME
601 PM EDT THU JUL 15 2021

.SYNOPSIS AND DROUGHT INTENSITY...
DROUGHT CONDITIONS IMPROVED ACROSS THE REGION SINCE THE LAST
UPDATE ON JULY 4TH. THE COMBINATION OF POST TROPICAL STORM ELSA
AND A PREDECESSOR RAIN EVENT BROUGHT WIDESPREAD PRECIPITATION TO
THE REGION. 

MODERATE DROUGHT CONDITIONS ARE OBSERVED ACROSS MOST OF NORTHERN 
SOMERSET COUNTY, MUCH OF PISCATQUIS COUNTY, AND PARTS OF SOUTHERN 
AND FAR NORTHERN PENOBSCOT COUNTY. THE REMAINDER OF THE REGION IS 
ABNORMALLY DRY, WITH THE EXCEPTION OF MOST OF WASHINGTON COUNTY 
AND SOUTHEAST AROOSTOOK COUNTY WHICH CURRENTLY ARE NO LONGER 
CLASSIFIED AS ABNORMALLY DRY. 

.PRECIPITATION...
PRECIPITATION FOR THE MONTH OF JUNE WAS MOSTLY WELL BELOW AVERAGE
RANGING FROM 25 TO 75 PERCENT OF NORMAL, WITH ONLY FAR NORTHERN 
AREAS RECEIVING 80 TO 110 PERCENT OF AVERAGE. RAINFALL INCREASED
SIGNIFICANTLY DURING THE FIRST HALF OF JULY WITH THE EXCEPTION OF
FAR NORTHERN MAINE. THE COMBINATION OF POST TROPICAL STORM ELSA 
AND A PREDECESSOR RAIN BROUGHT WIDESPREAD 1 TO 3 INCHES OF RAIN TO
THE REGION WITH 3 TO 5 INCH TOTALS IN PARTS OF HANCOCK, PENOBSCOT,
AND WASHINGTON COUNTIES. THROUGH THE FIRST TWO WEEKS OF JULY, 
PRECIPITATION RANGED FROM 200 TO 300 PERCENT OF NORMAL ACROSS THE 
DOWNEAST REGION AND INTO THE UPPER PENOBSCOT VALLEY. ACROSS THE 
CENTRAL HIGHLANDS AND SOUTHEAST AROOSTOOK COUNTY PRECIPITATION 
RANGED FROM 80 TO 130 PERCENT OF NORMAL. ACROSS FAR NORTHERN AREAS
PRECIPITATION WAS MORE SCANT WITH AMOUNTS RANGING FROM AS LITTLE 
AS 20 TO 30 PERCENT OF NORMAL IN THE SAINT JOHN VALLEY TO 60 
PERCENT OF NORMAL IN CARIBOU. 

.HYDROLOGIC CONDITIONS...
RIVER FLOWS: REMAIN BELOW AVERAGE FOR THIS TIME OF YEAR ACROSS THE
REGION. THE GREATEST DEPARTURES FROM NORMAL ARE ON THE SAINT JOHN
RIVER, AROOSTOOK RIVER, ALLAGASH, AND PISCATAQUIS RIVERS WITH 
AMOUNTS RANGING FROM 15 TO 40 PERCENT OF NORMAL. CONDITIONS ARE 
SOMEWHAT BETTER TO THE SOUTH ACROSS THE PENOBSCOT RIVERS WITH 
VALUES MOSTLY RANGING FROM 35 TO 60 PERCENT OF NORMAL. 

SEVEN TO 14 DAY STREAMFLOWS REMAIN BELOW AVERAGE ACROSS MOST OF
NORTHERN AND EASTERN MAINE. THE MOST RECENT 7 DAY STREAMFLOWS 
ARE IN THE 10TH PERCENTILE ACROSS PARTS OF NORTHERN AROOSTOOK 
COUNTY AND SOUTHERN PISCATQUIS COUNTY, AND BELOW AVERAGE (10TH TO
25TH PERCENTILE) ACROSS MUCH OF PENOBSCOT COUNTY. NORMAL TO ABOVE
NORMAL STREAMS RANGING FROM THE 50TH TO 90TH PERCENTILES ARE 
CURRENTLY OBSERVED ACROSS HANCOCK AND WASHINGTON COUNTIES AND INTO
SOUTHEAST AROOSTOOK COUNTY.

GROUNDWATER AND WATER STORAGE (LAKES/RESERVOIRS): A LONG-TERM 
IMPACT OF THE DROUGHT IS LOWER GROUNDWATER LEVELS. GROUNDWATER 
LEVELS ARE VERY SLOW TO RESPOND, AND ALSO CAN BE VERY SLOW TO 
RECOVER. MOST LAKES AND RESERVOIRS ACROSS THE REGION ARE RUNNING 
BELOW SEASONAL NORMAL VALUES ACROSS THE REGION, ESPECIALLY ACROSS 
CENTRAL AND NORTHERN AREAS WHERE RAINFALL DEFICITS ARE GREATEST.

.SUMMARY OF IMPACTS...
WATER RESOURCES: NONE AT THIS TIME. THERE HAVE BEEN SOME REPORTS
OF PRIVATE WELLS THAT HAVE RUN DRY IN AROOSTOOK AND PENOBSCOT
COUNTIES, BUT THE LOCATION OF THESE WELLS IS UNKNOWN. WE ARE NOT 
AWARE OF ANY COMMUNITY WATER RESTRICTIONS IN OUR REGION AT THIS 
TIME.

WILDFIRE CONDITIONS: THE MAINE FOREST SERVICE HAS REPORTED DRY 
CONDITIONS BETWEEN SIGNIFICANT RAINFALL EVENTS, LEADING TO A 
RELATIVELY HIGHER OCCURRENCE OF WILDFIRE EVENTS SO FAR THIS 
SEASON.

AGRICULTURAL CONDITIONS: NONE NOTED AT THIS TIME. GIVEN THAT MOST
FARMING ACROSS OUR REGION IS ACROSS THE NORTH AND EAST WHERE
THERE IS NO DROUGHT AND IN SOME LOCATIONS ABNORMALLY DRY, 
ESPECIALLY COMPARED TO LAST SUMMER THIS TIME, THERE HAS NOT BEEN 
AS MUCH STRESS ON POTATO AND OTHER LOCAL CROPS SUCH AS 
BROCCOLI. SOME CROPS IN THE AREA ARE REQUIRING IRRIGATION.


.DROUGHT MITIGATION ACTIONS...
THE STATE OF MAINE HAS ACTIVATED ITS DROUGHT TASK FORCE. HYDRO 
OPERATORS ARE MONITORING CONDITIONS AND BALANCING NEEDS OF LAKE 
LEVELS, HYDROELECTRIC POWER GENERATION NEEDS, AND DISCHARGES TO 
MAINTAIN STREAM FLOW AND RECREATION NEEDS DOWNSTREAM. 

IN RESPONSE TO ESCALATED DROUGHT, THE MAINE EMERGENCY MANAGEMENT
AGENCY HAS PUBLISHED AN ONLINE SURVEY FOR HOME OWNERS TO REPORT 
PRIVATE WELLS RUNNING DRY AND OPPORTUNITIES FOR ASSISTANCE:
HTTPS://MAINE-DRY-WELL-SURVEY-MAINE.HUB.ARCGIS.COM/.

.PRECIPITATION/TEMPERATURE AND HYDROLOGIC OUTLOOKS...
CPC'S OUTLOOK FROM DAYS 6 TO 14 FAVORS BELOW AVERAGE TEMPERATURES
ACROSS THE REGION. THE PRECIPITATION OUTLOOK CALLS FOR AN
INCREASED LIKELIHOOD OF BELOW AVERAGE PRECIPITATION. LONGER RANGE
OUTLOOKS FOR AUGUST CALL FOR AN INCREASED LIKELIHOOD OF ABOVE
AVERAGE TEMPERATURES AND CURRENTLY NO STRONG CLIMATE SIGNALS THAT
WOULD POINT TOWARD IT BEING UNUSUALLY DRY OR WET. 

THERE WILL BE SCATTERED SHOWERS AND THUNDERSTORMS AT TIMES DURING
THE NEXT WEEK WITH THE POTENTIAL FOR LOCALLY HEAVY RAINFALL, BUT
AT THIS TIME WIDESPREAD STEADIER RAINS ARE NOT EXPECTED. THIS WILL
LIKELY CAUSE MOST RIVERS AND STREAMS TO SLOWLY FALL DURING THE
NEXT WEEK. THERE IS THE POTENTIAL THAT DROUGHT CONDITIONS MAY
DEVELOP WHERE THERE CURRENTLY ARE NO DROUGHT CONDITIONS, AND MAY
WORSEN IN AREAS WHERE THERE IS CURRENT MODERATE DROUGHT. 

.NEXT ISSUANCE DATE...
THIS PRODUCT WILL BE UPDATED BY THE EVENING OF JULY 29TH UPON THE
RELEASE OF THE UPDATED U.S. DROUGHT MONITOR THAT DAY, OR SOONER 
WHEN OTHER SIGNIFICANT INFORMATION WARRANTS AN EARLIER UPDATE.
