National Weather Service: Hannibal storm damage caused by straight line winds


A representative from the National Weather Service says damaged caused in Hannibal on Monday night was due to straight line winds, but says a small tornado did touch down south of the city.

Jim Kramper, a weather observer with the National Weather Service office in St. Louis, tells WGEM News that his team's investigation in Hannibal indicates that straight line winds between 80-100 miles per hour hit the city, causing widespread damage to trees, power lines and buildings.

NWS field crews also inspected uprooted trees and damaged roofs in the city.

Kramper's team, however, did issue a final report at 8:30 p.m. Tuesday, indicating that a EF-1 tornado did touch down about a mile south of Hannibal Regional Hospital. The NWS report states that the tornado traveled 1.15 miles with a width of 50 yards.
