What to Do During a Tornado Warning in Mentor
If a tornado warning is issued specifically for Mentor or your immediate location, do not wait to see the tornado.
Move immediately to a safe shelter.
The safest location is an interior room on the lowest floor of a sturdy building, preferably away from windows. A basement provides additional protection when available.
If You Are at Home
Go to the basement if one is available. Otherwise, move to a small interior room on the lowest floor, such as a hallway, bathroom or closet.
Stay away from:
- Windows
- Exterior doors
- Large open rooms
- Glass
- Rooms with wide-span roofs
Protect your head and neck with your arms, pillows, blankets or another available covering.
If You Are Driving
Do not attempt to outrun a tornado by driving blindly through severe weather.
If possible, safely reach a sturdy building and shelter inside. Avoid stopping underneath bridges or overpasses, where wind and debris can create additional dangers.
Never drive through water covering a roadway. Heavy rainfall associated with severe storms can quickly create dangerous flooding.
If You Are Outdoors
Get inside a sturdy building immediately.
If no shelter is available and a tornado is approaching, seek the lowest possible area while protecting your head and neck. Avoid trees, vehicles and structures that could collapse.
Mentor Tornado Warning and Power Outage Concerns
Severe thunderstorms can produce widespread power disruptions even when a tornado does not occur.
Strong winds can bring down trees and utility lines, potentially leaving neighborhoods without electricity. Residents should avoid downed power lines and treat them as energized.
For local emergency information, residents can also monitor Lake County Emergency Management in Mentor.
Will More Severe Weather Affect Mentor?
The threat was not limited to a single storm. Cleveland-area forecasters expected additional rounds of showers and thunderstorms through the overnight period and into Friday.
That means residents should continue monitoring weather alerts even after one warning expires. A storm that passes through one part of Lake County does not necessarily mean the broader severe-weather threat has ended.
Tornado Warning vs. Tornado Watch: What Is the Difference?
Tornado Watch: Conditions are favorable for tornadoes. Residents should remain alert and be prepared to shelter quickly.
Tornado Warning: A tornado has been detected or indicated by radar. People in the warning area should take shelter immediately.
This distinction is particularly important during fast-moving Northeast Ohio storms because warnings can be issued and updated quickly.
