Traffic lights at a city intersection were not working properly briefly because of weather for part of Thursday, officials said.
The Sun Prairie Police Department said Thursday that traffic signals at Prairie Lakes Drive and Grand Avenue were in flash mode due to a lightning strike. Motorists were advised to use caution.
Police initially said the signals would possibly remain in flashing mode until Friday.
About 3 hours later, police said the traffic signals at Prairie Lakes and Grand were repaired and working normally.
