Description: The information contained in this shapefile includes tornado tracks for all 62 tornadoes that occurred on April 27, 2011 throughout the State of Alabama. Fields included: Tornado Name, EFScale, Counties Affected, Peak Wind Speed, Path Length, Maximum Width in Miles (MaxWidth), Start Time in Central Daylight Time, Begin Latitude, Begin Longitude, End Time, End Latitude, End Longitude, Maximum Width in Yards (Width_YDS), Segment Order based on Begin Time (Order_No), and Tornado Number from Statewide Track Map (Tor_No). THE DATA CONTAINED IN THE SHAPEFILE ARE EXPERIMENTAL.
All information was gathered through help from the Alabama Emergency Management Agency and prepared by the National Weather Service in Birmingham, Alabama. Special thanks goes to the Alabama Emergency Management Agency for help in organizing these data, and to the National Weather Service in Huntsville, AL and Mobile, AL for collaboration in obtaining the final statewide information.
