Survey Summary:
The tornado touched down 2 miles SE of Spring Creek just south of
BIA route #30 and remained over open field. The tornado tracked to
the east-northeast where it destroyed an outbuilding that was
built with heavy wood and anchored to a cement slab. The
outbuilding contents where thrown some 50yds to east up a hill.
The tornado crossed BIA route #30 where it strengthened,
destroying a single wide mobile home. The undercarriage of the
mobile home was tossed and crumpled 100yds from its foundation.
All walls where completely destroyed and the contents of the home
were thrown to the north to northeast. The tornado then moved
back into mostly open terrain before encountering some trees and
power poles just to the southwest of St. Francis. The circulation
then moved into St. Francis causing significant tree damage with
trees both uprooted and some trees near the catholic church had
their trunks snapped at the base. As the tornado passed through
the west side of St. Francis it caused significant roof damage to
the community center and an elderly living facility. The tornado
began to weaken slightly as it exited St. Francis and began to
move more toward the north-northeast and back over open terrain.
The tornado produced its last damage in Rosebud with the water
supply center and the adjacent storage facility receiving
signficant roof damage with the roofs being thrown toward the west
to southwest. The tornado dissipated 2 miles north of Rosebud.
