Overview

A line of strong to severe thunderstorms developed ahead of a dryline during the early morning hours across East Texas and Southeast Oklahoma. Several reports of wind damage were received from across the area, especially around the Umpire and Athens areas in Northern Howard County, Arkansas. As the storms moved into Northwest Louisiana, a supercell developed, which produced three tornadoes across the northern portions of Caddo, Bossier, and Webster Parishes. Two of the tornadoes, one near Mira, LA, and Interstate 49, and another in Springhill, LA, was recorded on video by several residents. Near Mira, about 40 people were at a gas station and took shelter in the freezer as the tornado passed just to the south.

After the storms passed, meteorologists from the National Weather Service in Shreveport deployed to survey the damage. The conclusions of the team are noted below. This information should be considered preliminary and subject to change as more information becomes available.

TOTAL TORNADO COUNT = 3

EF1 = 3
