		Brief Description: A severe thunderstorm produced a tornado as it moved into St. Tammany Parish. The tornado was first observed by the State Police on Interstate Highway 12 west of Covington. From data collected on a ground, damage survey by the National Weather Service, the tornado moved on a path slightly north of due east. The tornado moved across the downtown area of Covington and continued east for nearly 2 miles before lifting off the ground. Most of the damage along path indicated F1 damage, however, several areas near downtown Covington were classified as F2 damage. Parish officials reported 43 injuries were reported with tornado, though most were relatively minor. Six persons required and overnight stay in a hospital, including three pregnant women. Most of the damage to homes was due to large pine trees which had been toppled onto houses. In downtown Covington, a few large buildings lost roofs, had windows blown out, or suffered substantial damage. A large parish building suffered $500,000 damage. Media reports indicated cleanup would cost several million dollars. Just east of the downtown area, several cars were lifted and moved tens of feet by the tornado, and an empty tractor-trailer truck rig was blown over. Nearly 50 cars in a parking lot had their windows blown out by debris or by rapid pressure drop. The same parent thunderstorm spawned another tornado just south of Talisheek damaging a barn and a house. The damage path length at Talisheek was estimated. American Red Cross reports indicated 69 single family homes were destroyed or had major damage in St. Tammany Parish. Four public buildings were also heavily damaged.

		Brief Description: EVENT NARRATIVE: This strong tornado touched down just east of the Brookhaven-Lincoln County Airport and tracked east-northeast for five miles to near the Woolworth Community. The most significant damage occurred just south of Heucks Crossing along Beeson Road where two mobile homes were obliterated. The debris was swept from foundations with large debris, including furniture, and appliances thrown more than 100 yards. Additionally, numerous trees, both pines and hardwoods, were snapped and uprooted along with several power lines down along the path. A shop was also destroyed, camper trailer heavily damaged and two other homes suffered significant roof damage. EPISODE NARRATIVE: A small, but potent, storm system evolved and moved east across the region during the first half of the day. A large MCV (meso-scale convective vortex) developed across Central Louisiana during the morning hours and moved east adding an extra kick to the atmosphere and aided in generating a line of severe thunderstorms which produced five tornadoes and wind damage. All the severe weather was confined to the southern areas, generally along Highway 84, and extended from Natchez to Brookhaven to Laurel.
