The National Weather Service issued a tornado warning for parts of three counties in northeastern Oregon on Wednesday.
The tornado warning was in effect through 2:45 p.m. Wednesday in south central Umatilla County, northwestern Grant County and southeastern Morrow County.
The warning expired with no reports of tornado sightings.
Doppler radar showed a severe thunderstorm capable of producing a tornado, according to the National Weather Service. The storm was initially spotted near Monument moving northeast at 45 mph and producing golf ball-sized hail.
People in the warning area were advised to immediately take cover in the basement or an interior room on the lowest floor of a sturdy building.
Residents were also told to avoid windows and anyone outdoors or in a mobile home was asked to move to the closest shelter.
