GARRETSON, S.D. (AP) — The absence of injuries is keeping Garretson residents upbeat as they recover from a devastating storm.

Mayor Tim Mullin says the extent of the damage from the early Monday storm is still being assessed, but no one was hurt and "that's big."

The National Weather Service says wind speeds reached 100 mph. The agency doesn't know yet if it was a tornado or straight-line winds but says it doesn't really matter — wind that strong is damaging whether it's from one direction or rotating.

The Monday storms caused damage throughout eastern South Dakota. Strong winds also hit Pierre-Fort Pierre — even flipping a newly manufactured home onto its roof.

No injuries were reported, and a closed swimming pool, campground and tennis courts in Pierre were reopening Tuesday.

South Dakota officials have temporarily closed the Farm Island Recreation Area along the Missouri River near Pierre.

The South Dakota Game, Fish and Parks Department says the recreation area will reopen as soon as the park is cleaned up.

Officials say campers with reservations have been notified of the closure.
