Pat Shingleton for Oct. 25, 2012

In late October and early November, the Gulf Coast region typically experiences more thunderstorm activity. One reason is the transition from a tropical weather scenario to increasing frontal passages. The interaction of strong systems and lingering humidity triggers storms. On Oct. 29, 2002, a twister hit a section of southeast Baton Rouge, leveling trees and damaging roofs, and straight-line winds caused additional damage in Pearl River County, Miss. On Nov. 15, 2006, severe storms created rotation to produce a series of tornadoes tracking from Lake Pontchartrain. Touchdowns occurred in Greensburg and Tylertown, Miss., with a fatality in Montpelier. On Nov. 24, 2004, straight-line winds here sped eastward to Slidell, damaging 152 homes. Finally, a strong tornado damaged 70 homes and 4 buildings in Covington on Nov. 21, 1997. Fastcast: A repeat.
