$150M damage
What happened
Hurricane Katrina will likely go down as the worst and costliest natural disaster in United States history. The amount of destruction, the cost of damaged property/agriculture and the large loss of life across the affected region has been overwhelming. Catastrophic damage was widespread across a large portion of the Gulf Coast region. The devastation was not only confined to the coastal region, widespread and significant damage occurred well inland up to the Hattiesburg area and northward past Interstate 20. This hurricane has changed life as we know it across the Gulf Coast region which will take many years to return to normal.Hurricane Katrina was a very large and powerful storm which set several unfortunate records. This storm began as Tropical Depression 12 during the late afternoon and evening of August 23rd. The storm slowly moved northwest, became more organized, and was upgraded to Tropical Storm during the late morning of August 24th as it moved across the Central Bahamas. The Tropical Storm continued to become better organized as it moved slowly west toward Southern Florida. Katrina became a Category 1 Hurricane late in the afternoon on August 25th just before moving...

Raleigh, Smith County
1 death, $1M damage
What happened
This tornado started by downing some trees just southeast of Raleigh, near and across Highway 18. As the tornado moved northeast along Bailey Road and crossed County Road 130, it intensified and produced high end EF-1 damage, snapping and uprooting trees, taking shingles off roofs, and blowing skirting out from mobile homes. The tornado continued to strengthen as it moved northeast, and along County Roads 136, 107, and 105, it produced damage indicative of high end EF-2. A few mobile homes were destroyed and several homes and buildings sustained significant roof damage, along with extensive tree damage. Along County Road 105, a mobile home was picked up by the tornado, bounced along the ground a couple of times, and was then thrown into woods across the road, with debris scattered for at least a mile downstream, including the frame of the mobile home. The occupant of the mobile home was the first fatality of this tornado. The tornado continued northeast, and reached its most intense and widest point in the Smith County portion of the tornado just before crossing the county line at County Road 103. Here, in the central core of the tornado there was an area of completely mowed...

Mize, Smith County
$8.6M damage
What happened
This strong tornado developed from a long lived supercell thunderstorm, which had a history of producing tornadoes, that moved across a large portion of Southern and Central Mississippi. The tornado touched down just N of Mount Olive, in Covington county, and stayed on the ground for 28 miles across most of Smith county, where it dissipated around the Ted community just inside Jasper county. Where the tornado first touched down it was weak, F0, and only downed a few trees. As it moved NE, into Smith county, it quickly gained strength. F1 to F2 type damaged occurred across SW Smith county where hundreds of trees were snapped or uprooted and several homes and outbuildings had part or all of their roofs blown off. As the strong tornado approached Mize, MS, it became stronger and reached it maximum intensity, F3. Here the tornado was 600 yards wide and was significantly damaging nearly all the trees in its path. One mile to the SW of Mize, a mobile home was destroyed. The most significant damage occurred in Mize where the Attendance Center was nearly demolished. The top floor of the Attendance Center was almost completely taken off, 3 portable classrooms were destroyed along with...
