What & Why

A severe thunderstorm watch is issued by the National Weather Service (NWS) when weather conditions are conducive to the development of severe thunderstorms in a specific area. Unlike a warning, which means a severe storm is imminent or occurring, a watch simply means the potential exists. It's a heads-up, a signal to be prepared.

What constitutes a "severe" thunderstorm? According to the NWS, a thunderstorm is considered severe if it produces:

• Wind gusts of 58 mph (50 knots) or higher. These winds can cause significant damage.
• Hail that is 1 inch in diameter or larger. This is about the size of a quarter.
• A tornado. While not always present, the potential for tornadoes increases during severe thunderstorm events.

Why are severe thunderstorm watches issued? The main reason is to give people time to prepare. The NWS monitors atmospheric conditions, looking for specific ingredients that can fuel severe thunderstorms. These ingredients include:

• Atmospheric instability: Warm, moist air near the surface combined with colder air aloft creates an unstable environment, allowing thunderstorms to develop.
• Lift: Something must force the air to rise. This can be caused by fronts, sea breezes, or even mountains.
• Moisture: Ample moisture in the lower atmosphere is fuel for thunderstorms.
• Wind shear: Changes in wind speed and direction with height can cause thunderstorms to rotate and become more organized, increasing the risk of severe weather.

When these ingredients are present, the NWS issues a severe thunderstorm watch, alerting people to the increased risk. — Paterson, NJ Zip Codes: Find Yours & More

Benefits of a Severe Thunderstorm Watch:

• Preparation: Allows time to secure loose objects, move vehicles under cover, and review safety plans.
• Awareness: Heightens awareness of the potential for severe weather.
• Informed decisions: Enables individuals to make informed decisions about their activities, such as postponing outdoor events.

Risks Associated with Severe Thunderstorms:

• Damaging winds: Can cause structural damage to buildings and knock down trees and power lines.
• Large hail: Can cause significant damage to vehicles, roofs, and crops.
• Flooding: Heavy rainfall can lead to flash flooding, posing a significant threat to life and property.
• Tornadoes: Severe thunderstorms can spawn tornadoes, which are the most violent type of storm.
• Lightning: A constant threat during thunderstorms, lightning can cause injuries and fatalities.
