According to the NWS, a severe thunderstorm was spotted over West York and moving east at about 40 miles per hour. Forecasters warn of damaging wind gusts reaching up to 60 mph and heavy rain capable of causing flash flooding.

Storm Details and Areas Impacted

The storm is expected to affect several populated areas, including York, Weigelstown, Red Lion, Spry, Dallastown, Shiloh, and East York. The NWS advised residents to take immediate precautions, move indoors, and stay away from windows as the storm passes.

Lightning strikes, downed tree limbs, and power outages are possible as strong winds sweep through the region. Torrential rainfall could also cause dangerous road conditions, including flash flooding in low-lying areas and poor visibility for drivers.

Local emergency management officials urge residents to monitor real-time weather updates and follow instructions from authorities. Outdoor activities should be postponed until the warning expires or the storm passes safely.

Severe thunderstorm warnings are issued when radar or trained weather spotters detect a storm capable of producing damaging winds or large hail. This warning signals that conditions are dangerous and immediate protective action is needed.

Potential Impact and Safety Measures

Storms of this strength can bring down trees, power lines, and unsecured outdoor objects. Power interruptions may occur if winds damage electrical infrastructure. Residents are encouraged to charge mobile devices, keep flashlights ready, and avoid driving through flooded roads.

Those caught outside should seek sturdy shelter and avoid open fields, tall isolated trees, or metal objects. Flash flooding may develop quickly, especially in urban or poorly drained areas. Officials remind drivers: “Turn around, don’t drown” when encountering water-covered roads.
