11 days after Moore, Oklahoma had taken a blow by a devastating EF-5 tornado another EF-5 ravaged the community of El Reno and outlying areas. This tornado would make the record books and leave much more sorrow in its wake than anyone could begin to imagine. The May 31, 2013 El Reno, Oklahoma tornado was an astonishing 2.6 miles wide with a rating of an EF-5 (released June 4, 2013 by NWS), making it the largest EF-5 in recorded history. Storm chasers Jeff and Kathryn Piotrowski watched the storm develop on the west side of El Reno and become a massive inflow sucking machine. Jeff had never seen inflow being pulled into the tornado as this one.
It turned into a violent EF-5 in 30 seconds. Jeff was streaming live via ChaserCam™ LIVE to FoxNews and his up to the minute/second accounts of the tornados path and location were vital to those in this monsters path.
After the storm had passed it left a swath of damage 2.6 miles wide at the widest point. Less than 48 hours later, Jeff and Kathryn received the news that 3 of the world's pioneers in storm research, colleagues, friends and loved by everyone in the storm chasing community had died doing what they loved to do. Tim Samaras, Paul Samaras and Carl Young. Their passing sent a shockwave through the storm chasing community…and will change how people storm chase forever. They will be remembered for (among many other wonderful things) their passion for weather and their commitment to saving lives through vital research.
