Thunderstorms Across the Southeast U.S.; Elevated to Locally Critical Fire Weather in Colorado

A few strong to marginally severe thunderstorms are possible across the Southeast U.S. Friday. A Marginal Risk (Level 1 of 5) outlook has been issued. Strong winds and hail will be the main threats. Elevated to locally critical fire weather conditions will persist across south-central Colorado today due to dry conditions and gusty winds. Read More >

Overview
A very strong storm system brought severe weather and tornadoes to portions of East Texas and North Louisiana during the evening and nighttime of March 24, 2017. Survey teams from the NWS confirmed a total 6 tornadoes occurred. Several locations received significant straight-line wind damage with wind speeds near or above 100 mph.

Some of the most significant damage occurred in Ringgold in Bienville Parish, LA. Straight-line winds of around 100 mph lifted a roof off a church. As the roof came back down on the front of the cinder block building, the front walls were crushed and partially collapsed. All of the debris from the building was blown directly downwind from the church, and no debris was found in the grassy fields to the sides or behind the building. In addition, the tops of very tall pine trees in a densely wooded area on either side of the church were left intact. This is very indicative of straight-line wind damage.

Details of the survey are listed below.

Summary:

A waterspout developed over Toledo Bend Reservoir and moved inland at the Grapevine Estates subdivision as an EF1 tornado. Three boats were lifted out of the water, with two being deposited between 250 and 300 yards north of the lake and one on the back porch of a house. Three homes sustained minor siding or roof damage.

Summary:

An EF1 tornado began on the southwest side of Hagewood, just west of Highway 117. Although the primary damage was snapped trees, two businesses at the intersection of Highway 117 and Highway 6 sustained some damage. The first was a metal warehouse that lost some siding. Across the street, a pool supply business sustained some roof damage. There was also an I-beam structure behind the pool business that had several I-beams knocked down, including one that was blown over that had been attached to the concrete base. Several homes had minor roof damage, including one that had a corner of the roof lift enough for the ceiling to cave in. Several outbuildings were damaged or destroyed.

Summary:

The Ringgold Assembly of God Church had its roof lifted by straight-line winds. As the roof came back down, it crushed the un-reinforced cinder block walls near the front of the structure, which then partially collapsed. Portions of the roof structure were found approximately 25 yards away from the main building. Two-by-fours from the roof also pelted the home across the street, with one two-by-sour piercing the swimming pool slide in the back yard. All debris was found immediately down wind of the church.

A home about a half mile west of the church lost some shingles, and several trees were uprooted.
