Lightning Warning Signs You Shouldn't Ignore

Cloud-to-ground lightning is nearby if you notice one or more of these early signs. Seek shelter immediately to reduce the risk of lightning injury or even death.

• Increasing winds and a darkening sky. These are telltale signs of an approaching storm.
• dible thunder. Thunder is the sound created by lightning, so if thunder can be heard, lightning is near. You can determine how near (in miles) by counting the number of seconds between a flash of lightning and a thunderclap and dividing that number by five
•  
• A severe thunderstorm warning. The National Weather Service issues a severe thunderstorm warning whenever severe storms have been detected on weather radar or confirmed by storm spotters. Cloud-to-ground lightning is often the main threat of such storms.

• Where to Seek Shelter

  At the first sign of approaching lightning, you should quickly seek shelter, ideally in an enclosed building or other structure, away from windows. If you're at home, you may want to retreat to a central room or closet. If you cannot find shelter inside, the next best option is a vehicle with all of the windows rolled up. If for whatever reason, you are stuck outside, you should make sure to stand away from trees and other tall objects. Keep away from water and anything that is wet, as water is a strong conductor of electricity.

  Signs of an Immediate Strike

  When lightning strikes you or the area immediately nearby, you may experience one or more of these warning signs a few seconds beforehand.

   

  • Hair standing on end
  • Tingling skin
  • A metallic taste in your mouth
  • The smell of chlorine (this is ozone, which is produced when nitrogen oxides from lightning interact with other chemicals and sunlight)
  • Sweaty palms
  • A vibrating, buzzing, or crackling sound coming from metal objects around you

   

  If you notice any of these signs, it may be too late to avoid being struck and possibly injured or killed. However, if you find that you do have time to react, you should run as fast as you can to a safer location. Running limits the amount of time that both of your feet are on the ground at any given moment, reducing the threat from ground current (lightning that travels outward from the strike point along the ground surface).
