2007 Groundhog Day tornado outbreak The 2007 Groundhog Day tornado outbreak was a localized but devastating tornado event that took place in central Florida early on February 2, 2007. Early morning temperatures had risen well above average for the season; combined with increased moisture and a powerful jet stream, this created enough instability and wind shear for thunderstorms to rotate and spawn tornadoes. Due to the conditions, a long-tracked supercell formed and produced three tornadoes over one hour and seventeen minutes. The supercell resulted in a 70-mile (110-kilometer) trail of damage.

Tropical Storm Lee (2011) Tropical Storm Lee was the twelfth named storm and thirteenth system overall of the 2011 Atlantic hurricane season, developing from a broad tropical disturbance over the Gulf on September 1. It was designated as Tropical Storm Lee the next day. The system was rather large, and due to drifting, Lee brought flash flooding to the Gulf Coast. Flooding associated with the rains caused significant property damage in the areas, with drowning deaths reported in both Mississippi and Georgia. Elsewhere, the storm helped spread wildfires that destroyed homes and killed two people in Texas, and a traffic accident in Alabama resulted in one death. Rough surf offshore drowned one person in each of these states. Lee spawned 30 confirmed tornadoes in the United States. After becoming extratropical, Lee caused historic flooding in Pennsylvania, New York, and Canada, mainly Quebec and Ontario.

Tornado emergency A tornado emergency is an enhanced version of a tornado warning, which is used by the National Weather Service (NWS) in the United States during significant tornado occurrences in highly populated areas. Although it is not a new warning type from the NWS, issued instead within a severe weather statement (or in rare cases, in the initial tornado warning), a tornado emergency generally means that significant, widespread damage is expected to occur and a high likelihood of numerous fatalities is expected with a large, strong to violent tornado.
