NWS Confirms 9 Tornadoes During June 18 Severe Weather Outbreak Across Louisiana and Mississippi

The National Weather Service has confirmed that 9 tornadoes touched down across southeast Louisiana and coastal Mississippi during the severe weather outbreak on June 18.

Damage survey teams have spent the past several days assessing storm impacts and documenting damage paths left behind by multiple EF-0 and EF-1 tornadoes. Survey work remains ongoing in several areas, including Eden Isle in St. Tammany Parish, where meteorologists are still determining whether additional tornadoes occurred within broader areas of wind damage.

The strongest tornado confirmed so far was an EF-1 that tracked approximately 12.42 miles from the Treasure Isle area of St. Tammany Parish into Hancock County, Mississippi. The tornado reached estimated peak winds of 105 mph and grew to nearly 300 yards wide at times.

According to NWS survey teams, the tornado flipped a large boat near Treasure Isle before moving northeast through residential areas. Numerous trees were uprooted or snapped, roofs were damaged, outbuildings were destroyed, and at least 1 manufactured home suffered major structural damage after being shifted from its foundation.

Several other tornadoes were confirmed in the Houma area, including multiple EF-1 tornadoes with winds between 95 and 100 mph. Damage included collapsed walls, shattered windows, roof failures, overturned vehicles, downed power poles, and widespread tree damage.

An EF-1 tornado also tracked 7.26 miles from Bridge City through portions of New Orleans and toward the University of New Orleans area, causing scattered structural damage and numerous downed trees.

In Avondale, an EF-0 tornado injured 2 people and caused minor damage to homes and mobile structures.

Another EF-1 tornado was confirmed across Hancock and Harrison counties in Mississippi, uprooting large trees and causing property damage along a 6.38-mile path.

Despite the widespread damage caused by the storms, no fatalities were reported. Only 2 injuries have been confirmed.

The National Weather Service says all findings remain preliminary and could change as additional surveys are completed. Updated damage assessments are expected to be released after crews finish evaluating remaining storm damage areas.
