A warning counts here if the Weather Service listed Portsmouth city in it, even if the warned area covered only part of the county.
Alerts come from the National Weather Service and refresh every minute. Past warnings come from the Iowa Environmental Mesonet's archive of Weather Service products. During a warning, also listen to local radio, TV or a weather radio.
