| Brief Description: EVENT NARRATIVE: This strong tornado briefly touched down in the Oak Grove Community and was on the ground for 3/4 of a mile. Two homes had nearly the entire roof torn off and large wooden boards were wedged into the ground. Portions of awning were blown a mile away. Seven other homes sustained minor damage within the brief path. EPISODE NARRATIVE: A significant heavy rain and flash flooding event occurred on October 16 and into the first part of October 17. The event was set up by an anomalous pool of tropical type moisture (300% of normal) over the western Gulf of Mexico which was then pulled northward by strong low level winds in advance of a westward moving upper level disturbance. There were several other factors in play which contributed to the large amounts of rain, such as a northward moving warm front and a building upper ridge over the eastern Gulf of Mexico. The warm front helped lift the air while the building upper ridge served to weaken the westward moving upper disturbance. This then caused the progression of the heavy convective rains to slow and dump tremendous amounts of rain from southeast Texas to north and central Louisiana and then into west-central Mississippi. By late evening, dry mid level air began pushing east from Texas and allowed the heavy rain shield to move and exit the region by early Tuesday morning. Heavy rains were not the only weather type during this event, a couple of tornadoes occurred along with scattered reports of wind damage. What makes this event rare is that such a large area received 6 to 10 inches of rain and an even larger area received 4 to 6 inches. Embedded in that swath, a few locations in northern and central Louisiana received a whopping 12 to 17 inches! During this time of year, these kinds of rains usually occur from slow moving tropical cyclones, not from a warm front and westward moving upper disturbance. The result of all this rain was numerous reports of flash flooding, some even significant, across northeast Louisiana and west-central Mississippi. This event will go down in the record books for the amount of real estate covered by heavy rainfall and the several locations that measured extreme amounts. | |||||||||||

| Brief Description: EVENT NARRATIVE: This strong tornado touched down to the southwest of Sumrall and tracked east northeast across northern Lamar County and then into a small portion of extreme northwest Forrest County before dissipating. Approximately 25 homes were damaged, 16 of those suffering major damage or total destruction. The worst damage was along Old Salt Road, where a wood frame home on a concrete block foundation was totally destroyed, with the foundation cleared and the remnants of the home displaced dozens of yards away. A minivan was picked up and thrown/rolled a distance of approximately 150 yards, landing on top of a tractor and totally destroyed. Some large trees at this location were snapped at the base, denuded, and partially debarked. Heavy damage of F2 intensity was also observed along Foster Road, JD Hatten Road, and Rocky Branch road. Large swaths of trees were snapped and uprooted, and a few frame homes totally lost their roofs. Other damage along the path was weaker and generally of F1 intensity. The tornado then crossed Highway 42 and entered extreme northwest Forrest County. The total path length across Lamar and Forrest Counties was 13 miles. EPISODE NARRATIVE: An intense fall cyclone developed over the region and produced an episode of severe weather which included tornadoes. This strong weather system developed as a very strong jet stream, with winds between 160-200 mph, slammed into Oregon and Washington State. All that energy moved over the Rocky Mountains and caused a strong area of surface low pressure to develop. This low intensified as it moved east across the Red River Valley and then lifted across Arkansas and into Tennessee as it deepened to 990 mb! The strength of this deepening low caused warm and unstable air to lift northward across Louisiana and into central Mississippi. It was this northward moving warm front that became the focus of an area where tornadic supercell thunderstorms could thrive in an unstable and highly sheared environment. This large and powerful storm system produced numerous tornadoes across the south and south eastern United States where many were of the strong (F2 or F3) variety. Within the Jackson, MS forecast area, there were a total of 5 tornadoes to impact the counties serviced. Two F3s, one in Lamar County and the other in Jones County. The Jones County tornado actually contained a satellite tornado, F1, which briefly rotated around the parent tornado. Next was an F1 tornado in southern Marion County which was actually the end of a strong tornado that moved out of Walthall County. Lastly, a brief F1 tornado occurred in central Lamar County. Tornadoes were not the only type of severe weather, scattered wind damage also occurred across northeast Louisiana and portions of central Mississippi between midnight and 10 am Wednesday November 15th 2006. | |||||||||||
