Three tornadoes touched down in Iowa and South Carolina over the past two days, part of a broader severe weather outbreak that also produced 61 damaging wind reports and five large hail reports nationwide, according to the Storm Prediction Center.
Confirmed twisters struck Folly Beach, South Carolina, and an area 2 miles southwest of the Cedar Rapids Municipal Airport in Iowa, the Storm Prediction Center said in its post-event survey. The reports span two states, underscoring how the same weather system produced tornadic activity across a wide geographic range rather than a single localized event.
The tornado threat has largely passed, but three weather alerts remained active Saturday across Iowa and South Carolina, according to the National Weather Service, as forecasters continued to monitor conditions in the wake of the outbreak. The National Weather Service offices covering both states issued the advisories tied to the same weather system responsible for the confirmed twisters.
The scale of the wind and hail reports — 61 damaging wind reports and five large hail reports over 48 hours — points to a severe thunderstorm complex that extended well beyond the tornado tracks themselves. Damaging wind reports of that volume typically accompany a squall line or cluster of supercells capable of producing scattered structural and tree damage across multiple counties, though the Storm Prediction Center’s data does not specify individual damage estimates.
Cedar Rapids sits in eastern Iowa, an area that saw its confirmed tornado track just southwest of the municipal airport. On the opposite end of the outbreak, Folly Beach lies on the South Carolina coast near Charleston, where the tornado was confirmed as well. The distance between the two confirmed touchdowns illustrates how the parent weather system tracked across a large swath of the central and southeastern United States before or during the reporting window.
With confirmed reports now in hand, the National Weather Service and Storm Prediction Center will continue to assess whether additional tornadoes are confirmed as survey teams complete damage assessments in the affected areas. Residents in Iowa and South Carolina should continue monitoring official alerts, as three warnings remained in effect at last check even as the most severe activity had passed. No additional tornado warnings beyond the three active alerts were reported in the data reviewed.
