RIVER VALLEY (KNWA/KFTA) — The National Weather Service has surveyed the damage from Monday night’s (May 3rd) radar confirmed tornado in the Ft Smith/ Van Buren area.
A damage swath from the same storm in the Roland, OK area was surveyed as well. A third tornado was confirmed in the Dyer area on Thursday, May 6.
Based on the degree of damage surveyed, the NWS in Tulsa has rated the three tornadoes as EF-1s.
Roland, OK EF-1 Tornado
The first tornado surveyed developed on the east side of Muldrow, OK. It did cross into Arkansas where it continued to produce damage until it lifted west of Rena, AR.
It was rated an EF-1 on the Enhanced Fujita scale. Winds were originally estimated at 95-105 mph. They were upgraded to 100-110 later.
Fort Smith and Van Buren, AR EF-1 Tornado
The second tornado surveyed actually touched down before the Roland tornado around 9:33 PM on May 3rd. This was the tornado that ripped through parts of Fort Smith and Van Buren.
This twister was rated an EF-1 tornado. Wind speeds reached 100-110 mph. It touched down near Muldrow, OK as well. It continued northeast for almost 16 miles, crossing the Arkansas River twice, and crossing I-49 as well. It is clear that the tornado traveled further to the northeast, and another investigation will be required to determine where exactly the vortex lifted.
Dyer, AR EF-1 Tornado
This EF-1 tornado stayed on the ground for nearly three miles and began just north of Dyer. The tornado uprooted trees and blew down power poles.
