Essential Thunderstorm Preparedness During Heat Waves

Heat waves can increase the likelihood of severe thunderstorms, making it crucial to be prepared. Here's how to stay safe:

What Are Severe Thunderstorms?

Severe thunderstorms are defined by the National Weather Service as storms that produce hail at least an inch in diameter or winds exceeding 58 mph. These storms can also bring lightning, heavy rainfall, and even tornadoes. (weather.gov)

How Do Heat Waves Affect Thunderstorm Risk?

Heat waves provide the necessary conditions—moisture and instability—for thunderstorms to form. The intense heat can lead to rapid storm development, increasing the risk of severe weather. (weather.gov)

How Can I Prepare for Severe Thunderstorms During a Heat Wave?

• Stay Informed: Regularly check weather forecasts and listen to local news or a NOAA Weather Radio for updates on severe weather watches and warnings. (weather.gov)

• Create a Communication Plan: Establish a family emergency plan that includes a safe meeting place and contact information. Designate a safe room in your home, such as a basement or an interior room on the lowest floor with no windows. (weather.gov)

• Prepare Your Home: Trim trees and branches near your house. Secure loose objects outdoors, close windows and doors, and move valuable items inside or under sturdy structures. (weather.gov)

What Should I Do During a Severe Thunderstorm?

• Seek Shelter: If a severe thunderstorm warning is issued, go to your designated safe room immediately. Bring your pets with you if time allows. (weather.gov)

• Stay Indoors: Avoid windows and stay away from exterior walls. Do not use corded phones or electrical appliances. Mobile homes are especially vulnerable; if possible, seek shelter in a more secure building. (weather.gov)

• Avoid Water: If you're near water, such as a pool or lake, get out immediately. Water is a good conductor of electricity, and lightning can strike water, posing a significant risk. (weather.gov)

What Should I Do After a Severe Thunderstorm?

• Wait for Official All-Clear: Do not leave your shelter until authorities confirm it's safe. Severe weather can escalate quickly, and conditions may still be hazardous. (weather.gov)

• Check for Hazards: Look for downed power lines, flooding, or structural damage. Avoid touching electrical equipment if it's wet or if you are standing in water. (weather.gov)

• Stay Informed: Continue to monitor weather updates for any additional warnings or advisories. Severe weather can occur in succession, so remain vigilant. (weather.gov)

How Can I Stay Safe from Lightning?

• When Thunder Roars, Go Indoors: If you can hear thunder, you're close enough to be struck by lightning. Seek shelter in a sturdy building or hard-topped vehicle immediately. (weather.gov)

• Avoid Electrical Appliances: Do not use corded phones, computers, or other electrical equipment during a thunderstorm. Lightning can cause electrical surges that may result in injury or damage. (weather.gov)

How Can I Help My Community Prepare?

• Share Information: Educate friends and family about severe thunderstorm risks and safety measures. Encourage them to create their own emergency plans. (weather.gov)

• Stay Alert: Be aware of local weather patterns and share information about potential severe weather with neighbors. Community preparedness can enhance overall safety. (weather.gov)

By understanding the risks associated with heat waves and severe thunderstorms, and by taking proactive steps to prepare, you can significantly enhance your safety and that of your community.
