Severe thunderstorm warning issued for Buena Vista County, 60 mph winds possible
Storm Lake, Alta, Newell and Truesdale were under a warning as 60 mph winds threatened roofs, siding and trees across Buena Vista County.
Buena Vista County went under a severe thunderstorm warning on June 17 as radar showed wind gusts near 60 mph moving southeast toward Storm Lake, Alta, Newell and Truesdale. The warning said roofs, siding and trees could be damaged, and urged residents to move to interior rooms on the lowest floor.
The warning came while a broader severe thunderstorm watch was already in place until 11 a.m. CDT for Buena Vista County and much of Iowa. That put the county in the middle of a larger severe-weather setup that stretched across the state during the morning hours.
National Weather Service forecasters in Des Moines later said a line of storms swept across Iowa from northwest to southeast in the early morning of June 17. The agency said the system produced a swath of 60 to 70-plus mph winds, with sporadic gusts above 80 mph and a peak reported gust of 94 mph at Marshall County airport.
The storm line left behind widespread tree damage, snapped power poles and damage to homes and outbuildings, according to the National Weather Service summary. A broad band of 1 to 3-plus inches of rain also fell from central to southeast Iowa, adding another layer of disruption to communities already dealing with strong wind damage.
Buena Vista County also appeared in the National Weather Service Sioux Falls hazardous weather outlook on June 17. That outlook said severe storms were not expected in that area at the time, but localized wind gusts could still strengthen to 50 to 60 mph, a reminder that conditions can intensify quickly even when the threat seems limited.
The June 17 warning fit into an active run of severe weather that has repeatedly threatened western and northwest Iowa communities this spring and summer. For residents in Buena Vista County, the key response remains the same when a warning is issued: get inside, move low, and stay away from windows until the danger passes.
