..PUBLIC INFORMATION STATEMENT
 
 
...NWS DAMAGE SURVEY FOR THE APRIL 9, 2021 SEVERE THUNDERSTORM AND  
TORNADO EVENT...  
   
SOUTHERN LITTLE RIVER COUNTY THUNDERSTORM WIND
 
 
ESTIMATED PEAK WIND: 90 MPH  
PATH LENGTH /STATUTE/: 17 MILES  
PATH WIDTH /MAXIMUM/: 8 MILES  
FATALITIES: 0  
INJURIES: 0  
 
START DATE: 04/09/2021  
START TIME: 11:22 PM CDT  
START LOCATION: FOREMAN / LITTLE RIVER COUNTY / AR

SURVEY: A STRONG SQUALL LINE WITH AN EMBEDDED SUPERCELL MOVED  
FROM SOUTHEAST MCCURTAIN COUNTY IN OKLAHOMA THROUGH SOUTHERN  
LITTLE RIVER COUNTY, AR AND INTO WESTERN HEMPSTEAD COUNTY, AR LATE  
FRIDAY NIGHT WITH ESTIMATED WIND SPEEDS AROUND 70-90 MPH. WHILE  
OUR SURVEY WAS ONLY CONDUCTED IN LITTLE RIVER COUNTY, BASED OFF  
OTHER NON-SURVEY REPORTS, WE BELIEVE THAT THE SWATH OF DAMAGE  
EXTENDED UPSTREAM INTO MCCURTAIN COUNTY, OK AND DOWNSTREAM INTO  
WESTERN HEMPSTEAD COUNTY JUST PAST FULTON, AR WITH A TOTAL LENGTH  
AROUND 40-60 MILES. IN THE MIDST OF THIS SWATH OF WIND DAMAGE, OUR  
SURVEY DID FIND A SHORT EMBEDDED EF-1 TORNADO APPROXIMATELY 5  
MILES SW OF ASHDOWN. WITH THE EXCEPTION OF THE WEAK TORNADO, MOST  
OF THE DAMAGE CONSISTED OF TREES BEING UPROOTED OR SNAPPED IN AN  
EAST TO SOUTHEAST DIRECTION. THERE WAS ALSO SOME OCCASIONAL  
STRUCTURAL DAMAGE THAT MAINLY CONSISTED OF ROOFING MATERIAL OR  
SHINGLES ON HOMES AND OUT BUILDINGS. IN ADDITION, THERE WERE ALSO  
A FEW OTHER STRUCTURES THAT WERE CONSIDERABLY DAMAGED BY UPROOTED  
TREES.  
 
A SPECIAL THANKS GOES OUT TO OUR EMERGENCY MANAGEMENT PARTNERS IN  
LITTLE RIVER, HEMPSTEAD, AND MILLER COUNTIES FOR THEIR HELP AND  
ASSISTANCE WITH THE SURVEY PROCESS.  
   
TORNADO - SOUTHERN LITTLE RIVER COUNTY
 
 
RATING: EF1  
ESTIMATED PEAK WIND: 90 MPH  
PATH LENGTH /STATUTE/: 2.41 MILES  
PATH WIDTH /MAXIMUM/: 150.0 YARDS  
FATALITIES: 0  
INJURIES: 0  
 
START DATE: 04/09/2021  
START TIME: 11:31 PM CDT  
START LOCATION: 6 SW ASHDOWN / LITTLE RIVER COUNTY / AR  
START LAT/LON: 33.6219 / -94.2196  
 
END DATE: 04/09/2021  
END TIME: 11:33 PM CDT  
END LOCATION: 5 SW ASHDOWN / LITTLE RIVER COUNTY / AR  
END LAT/LON: 33.6198 / -94.1777  
 
SUMMARY: A BRIEF EF-1 TORNADO CROSSED OVER LITTLE RIVER 21 AND THE  
INTERSECTION OF LITTLE RIVER 15 AND LITTLE RIVER 713 DOING  
CONCENTRATED CONVERGENT TREE DAMAGE IN THE MIDST OF MUCH WIDER  
STRAIGHT LINE WIND DAMAGE THROUGHOUT THE SOUTHERN PORTION OF  
LITTLE RIVER COUNTY. DAMAGE TO STRUCTURES IN THE TORNADO PATH WAS  
VERY MINIMAL. IT IS POSSIBLE THAT THE TORNADO EXTENDS FARTHER THAN  
OUR SURVEY INDICATES, HOWEVER, THE ACTUAL SURVEY LENGTH WAS  
LIMITED BY ROAD ACCESS.  
 
A SPECIAL THANKS GOES OUT TO OUR EMERGENCY MANAGEMENT PARTNERS IN  
LITTLE RIVER COUNTY FOR THEIR HELP AND ASSISTANCE WITH THE SURVEY PROCESS.  
 
EF SCALE: THE ENHANCED FUJITA SCALE CLASSIFIES TORNADOES INTO
