The University of Iowa campus will take part in the normal, monthly testing of Johnson County's outdoor severe weather alert system at 10 a.m. Wednesday, April 3.

During testing last week as part of National Severe Weather Awareness Week, about 15 of the county’s sirens failed to sound on the first try and required use of a backup activation system. Officials traced the failure to a recent software upgrade and believe the problem has been fixed.

To be certain, the county is resuming its normal testing for this week, although plans originally were to skip April’s testing since it would come so soon after last week's drill.
