METEOROLOGISTS WITH THE NATIONAL WEATHER SERVICE AND RESEARCHERS FROM 
THE UNIVERSITY OF OKLAHOMA CONTINUE TO INVESTIGATE INFORMATION 
RELATED TO THE MAY 31 EL RENO TORNADO.

WITH THIS INVESTIGATION... THE TORNADO HAS BEEN UPGRADED TO AN EF5 
TORNADO BASED ON VELOCITY DATA FROM THE RESEARCH MOBILE RADAR DATA 
FROM THE UNIVERSITY OF OKLAHOMA RAXPOL RADAR. IN ADDITION... THE 
WIDTH OF TORNADO WAS MEASURED BY THE MOBILE RADAR DATA TO BE 2.6 
MILES AFTER THE TORNADO PASSED EAST OF US HIGHWAY 81 SOUTH OF EL 
RENO. THIS WIDTH IS THE WIDTH OF THE TORNADO ITSELF AND DOES NOT 
INCLUDE THE DAMAGING STRAIGHT-LINE WINDS NEAR THE TORNADO AS
