..DROUGHT CONDITIONS WORSEN
 
 
.SYNOPSIS:  
 
.DROUGHT INTENSITY AND EXTENT: ACCORDING TO THE APRIL 8 RELEASE OF  
THE U.S. DROUGHT MONITOR, EXTREME (D3) DROUGHT COVERED PERKINS,  
EASTERN HARDING, AND NORTHERN ZIEBACH COUNTIES. SEVERE (D2) DROUGHT  
COVERED ALMOST ALL OF THE REST OF NORTHWESTERN SOUTH DAKOTA AND  
NORTHEASTERN WYOMING, INCLUDING MOST OF CAMPBELL, CROOK, WESTON,  
WESTERN HARDING, SOUTHWESTERN PERKINS, BUTTE, LAWRENCE, MEADE,  
SOUTHERN ZIEBACH, NORTHERN HAAKON, AND NORTHERN PENNINGTON COUNTIES.  
AREAS OF SOUTHWESTERN SOUTH DAKOTA CONTINUED TO BE IN MODERATE  
DROUGHT, INCLUDING SOUTHERN PENNINGTON, CUSTER, FALL RIVER, OGLALA  
LAKOTA, WESTERN JACKSON, AND SOUTHERN HAAKON COUNTIES. CONDITIONS  
ACROSS SOUTH-CENTRAL SOUTH DAKOTA WERE ABNORMALLY DRY (D0),  
INCLUDING BENNETT, MELLETTE, TODD, AND TRIPP COUNTIES.  
 
.PRECIPITATION: SO FAR THIS SPRING, PRECIPITATION HAS BEEN AROUND  
AVERAGE ACROSS SOUTHWESTERN SOUTH DAKOTA AND THE BLACK HILLS, BUT  
BELOW AVERAGE ACROSS NORTHESTERN WYOMING AND NORTHWESTERN SOUTH  
DAKOTA.  
 
.HYDROLOGIC CONDITION: WHEN COMPARED WITH CLIMATOLOGY, STREAMFLOWS  
REMAIN AROUND NORMAL FOR THIS TIME OF THE YEAR. SNOW ACCUMULATIONS  
ARE BEGINNING TO LEVEL OFF, WITH SNOW ACCUMULATION SEASON ENDING A  
COUPLE OF WEEKS EARLIER THAN AVERAGE.  
 
.SUMMARY OF IMPACTS:  
 
.AGRICULTURAL IMPACTS: SOIL MOISTURE PROFILES CONTINUE TO BE DRY,  
ESPECIALLY ACROSS NORTHWESTERN SOUTH DAKOTA AND NORTHEASTERN  
WYOMING. PASTURE CONDITIONS ARE POOR AND SUPPLEMENTAL FEEDING OF  
CATTLE IS COMMON ACROSS THE ENTIRE AREA.  
 
.HYDROLOGIC IMPACTS: NUMEROUS STOCK PONDS AND DUGOUTS REMAIN DRY OR  
CONTAIN WATER OF POOR QUALITY.  
 
.FIRE HAZARDS: DEAD CURED FUELS, WHICH ARE SUSCEPTIBLE TO IGNITIONS,  
AND LACK OF SNOW COVER, COMBINED WITH LITTLE TO NO MOISTURE, IS  
RESULTING IN AN INCREASED RISK OF FIRES AND FIRE SPREAD FOR THIS  
TIME OF THE YEAR.  
 
.DROUGHT MITIGATION ACTIONS: NONE REPORTED.  
 
.LOCAL DROUGHT OUTLOOK: THE OUTLOOK THROUGH MID APRIL INDICATES IT  
WILL BE DRIER THAN AVERAGE WITH TEMPERATURES AROUND AVERGE.  
 
LOOKING FURTHER OUT THROUGH THE SPRING AND INTO THE SUMMER, THERE IS  
A GREATER CHANCE OF ABOVE-AVERAGE TEMPERATURES AND BELOW-AVERAGE  
PRECIPITATION. THE MONTHLY AND SEASONAL DROUGHT OUTLOOKS CALL FOR  
DROUGHT PERSISTENCE AND DROUGHT CONDITIONS WORSENING ACROSS THE  
ENTIRE AREA THROUGH THE END OF JUNE.  
 
.NEXT ISSUANCE DATE: THIS PRODUCT WILL BE UPDATED IN MAY OR AS  
CONDITIONS CHANGE.
