Oklahoma City–Forest Park, Oklahoma
Fujitascale:F3
Casualties:57 injuries
Damages:$2.5 million
Affected:Eastern Oklahoma City metro
Enhanced:no

This very destructive, rain-wrapped F3 tornado embedded within a 3adj=midNaNadj=mid swath of up to 2adj=midNaNadj=mid hail and straight-line winds of nearly 100mph first touched down in the Rancho Village community in Southern Oklahoma City. It skipped northeastward, causing heavy damage to homes, businesses, trees, gardens, shrubs, and power lines in the Heronville, Capitol Hill, and Central Capitol Hill neighborhoods. It briefly paralleled the North Canadian River (now known as the Oklahoma River) before crossing it and moving through the present-day Boathouse District, just barely missing Downtown Oklahoma City, where oil derricks were blown over. The neighborhoods of Carverdale, Edwards Community, Dodson Heights, and Garden Neighborhood Council were then hit as well before the tornado struck Forest Park, Oklahoma. The Rock Manor Estates was heavily damaged before the tornado began to move out of populated areas. It then destroyed some crops before dissipating.[2]

The tornado traveled 11.7miles, was 333yd wide and caused $2.5 million in damage. Two homes were destroyed, 40 others were heavily damaged, and 1,500 others had minor damage. There were 57 injuries, only seven of which were minor, with some people only narrowly escaping death. As a whole, the storm itself caused $4 million in damage to the city. This event may have consisted of several small tornadoes or sub-vortices that grazed rooftops.[2]
