A tornado warning means conditions are favorable for a tornado or that a tornado has been detected by radar or reported. Because tornadoes can develop quickly, residents should not wait for additional confirmation before moving to shelter.
Why Severe Storms Can Become Tornadic
Strong thunderstorms can produce tornadoes when several atmospheric ingredients come together, including instability, strong winds and changes in wind speed or direction with height.
In western Pennsylvania, thunderstorms can also produce damaging straight-line winds, large hail, intense rainfall and frequent lightning. Additionally, storms moving repeatedly over the same locations can create a secondary flash-flood threat.

What Residents Should Do During a Tornado Warning
If a tornado warning is issued for your location:
- Move indoors immediately.
- Go to a basement or the lowest level of a sturdy building.
- If there is no basement, use a small interior room away from windows.
- Put as many walls as possible between you and the storm.
- Protect your head and neck with your arms, a helmet, or sturdy cushions.
- Stay away from windows, doors and exterior walls.
- Do not attempt to outrun a tornado in a vehicle if safe shelter is nearby.
- If you are driving and cannot reach a sturdy building, pull over safely and assess your options rather than driving into hazardous conditions.
Storm Damage and Power Outage Potential
Severe thunderstorms can damage trees, power lines, roofs and other structures even when a tornado does not occur. Downed power lines can remain dangerous long after the storm has passed.
Residents should avoid damaged areas and never approach a fallen power line.
Additionally, heavy rain may create dangerous road conditions and localized flooding. Never drive through water covering a roadway.
