The rumble of thunder, the flash of lightning – summer brings not just sunshine and warmth, but also the potential for powerful thunderstorms. While most thunderstorms are fleeting affairs, some can pack a serious punch. This is where severe thunderstorm watches come into play, alerting communities to the possibility of dangerous storms and urging residents to be prepared.

What is a Severe Thunderstorm Watch?

Issued by the National Weather Service (NWS) or Environment Canada (depending on your location), a severe thunderstorm watch signifies that conditions are favorable for the development of severe thunderstorms within a specific watch area. These storms may produce one or more of the following:

• Large hail (generally exceeding 2 cm in diameter)
• Damaging winds (often exceeding 90 km/h)
• Torrential rainfall (capable of causing flash flooding)

What a Watch Doesn’t Mean:

It’s important to understand that a watch doesn’t guarantee a severe storm will occur. It simply indicates an elevated risk. However, it serves as a crucial heads-up, allowing residents to take precautionary measures in case a severe storm develops.

What to Do When a Severe Thunderstorm Watch is Issued:

• Stay Informed: Monitor weather forecasts closely through reliable sources like the NWS or Environment Canada websites, or weather apps on your phone.
• Review Your Emergency Plan: Do you have a family emergency plan? Now is the time to dust it off and ensure everyone in the household is familiar with it. This plan should include designated shelter locations, emergency contact information, and a communication strategy.
• Prepare Your Home: Secure loose outdoor furniture, bring potted plants indoors, and clear gutters and downspouts of debris to prevent flooding.
• Charge Electronics: Ensure your phone and any other essential electronics are fully charged in case of a power outage.
• Gather Supplies: Stock up on non-perishable food, bottled water, and essential medications in case you become trapped or experience power outages.
• Assemble an Emergency Kit: Create an emergency kit containing a flashlight, batteries, a first-aid kit, a radio, and other essentials to last for at least 72 hours.

The Difference Between a Watch and a Warning:

While a watch signifies a potential risk, a severe thunderstorm warning is issued when a severe thunderstorm is imminent or already occurring. If a warning is issued, take immediate action to seek shelter in a sturdy, below-ground location away from windows.

Staying Safe During a Severe Thunderstorm:

• Never drive through flooded roadways.
• Avoid open fields, tall trees, and bodies of water.
• If caught outdoors, seek shelter in a sturdy building or low-lying terrain.
• If you are in a car, stay inside but pull over away from trees and power lines.

Beyond the Watch: Weather Preparedness Matters

Severe thunderstorm watches serve as a valuable tool for preparedness. By understanding what they signify and taking proactive measures, communities can significantly reduce the risks associated with severe weather events. Remember, an informed and prepared community is a resilient community.

Living in a region prone to severe thunderstorms, it’s essential to be weather-savvy. Familiarize yourself with the different types of weather alerts, have a plan in place, and assemble an emergency kit. By taking these steps, you and your family can navigate even the most unexpected summer storms with greater peace of mind.
