Event narrative (NOAA)
This tornado is labeled Tornado B2 (Segment #1 of the Calumet-El Reno-Piedmont-Guthrie tornado). This tornado began very close to the Caddo/Canadian county border and quickly became a strong/violent tornado. The tornado destroyed numerous trees, many of them were debarked, before crossing Interstate 40. Three people died in vehicles near the I-40 Calumet exit, and two other fatalities occurred just northeast of that location. Cars were thrown thousands of feet off the roadways. It is believed that the tornado reached its maximum intensity just after crossing I-40, and it was here that a mobile radar measured winds of greater than 210 mph just off the surface. The El Reno Oklahoma Mesonet station (5 miles west) measured wind gusts of 131 and 151 mph. From this location, the tornado continue
