Severe Thunderstorm Warning: Causes and Characteristics
Severe thunderstorms are a type of thunderstorm that produces intense rainfall, hail, lightning, and sometimes tornadoes. They are most common in the spring and summer months, and they can occur anywhere in the world.
The meteorological conditions that lead to severe thunderstorms include:
- Warm, moist air near the ground
- Cold, dry air aloft
- A strong wind shear (change in wind speed and direction with height)
Typical Characteristics
Severe thunderstorms are characterized by their intense rainfall, hail, lightning, and sometimes tornadoes.
- Rainfall: Severe thunderstorms can produce rainfall rates of more than 1 inch per hour. This can lead to flash flooding, especially in low-lying areas.
- Hail: Severe thunderstorms can produce hail that is 1 inch in diameter or larger. Hail can damage cars, homes, and crops.
- Lightning: Severe thunderstorms can produce frequent lightning strikes. Lightning is a major cause of injuries and deaths in the United States.
- Tornadoes: Severe thunderstorms can produce tornadoes. Tornadoes are violent, rotating columns of air that can cause widespread damage.
Levels of Thunderstorm Severity, Severe thunderstorm warning
The National Weather Service (NWS) uses a scale to classify the severity of thunderstorms. The scale is based on the following factors:
- Wind speed
- Hail size
- Lightning frequency
The NWS has three levels of thunderstorm severity:
- Severe: Winds of 58 mph or greater, hail 1 inch in diameter or larger, or frequent lightning
- Moderate: Winds of 40-57 mph, hail 0.75-0.99 inches in diameter, or occasional lightning
- Marginal: Winds of 30-39 mph, hail 0.5-0.74 inches in diameter, or isolated lightning
Severe Thunderstorm Warning
Severe thunderstorms can bring a range of hazardous conditions, including torrential rainfall, damaging winds, hail, and lightning. These storms can cause widespread property damage, injuries, and power outages.
Impacts of Severe Thunderstorms
– Property Damage: Severe thunderstorms can cause extensive damage to homes, businesses, and infrastructure. High winds can rip off roofs, shatter windows, and topple trees. Hail can damage cars, crops, and buildings. Flooding can cause basements to flood, damage foundations, and wash away roads.
– Injuries: Severe thunderstorms can also cause injuries, including cuts, bruises, and broken bones. Lightning strikes can be fatal.
– Power Outages: Severe thunderstorms can also cause power outages, which can disrupt essential services such as water and communication.

Severe Thunderstorm Warning: Forecasting and Tracking
Severe thunderstorm warnings are issued by the National Weather Service (NWS) when radar or satellite indicates that a thunderstorm is producing, or is likely to produce, hail of one inch or greater in diameter, damaging winds of 58 mph or greater, or a tornado. Warnings are typically issued for areas within 25 miles of the storm’s path.
The NWS uses a variety of tools to forecast and track severe thunderstorms, including:
* Radar: Radar can detect the location, intensity, and movement of thunderstorms. NWS meteorologists use radar to identify storms that are likely to produce severe weather.
* Satellite: Satellites can provide information about the structure and evolution of thunderstorms. NWS meteorologists use satellite imagery to track the movement of storms and to identify storms that are likely to produce severe weather.
* Spotter reports: Spotter reports provide NWS meteorologists with information about the severity of thunderstorms. Spotters are trained volunteers who report on the weather conditions in their area.
When the NWS issues a severe thunderstorm warning, it is important to take shelter immediately. Stay indoors and away from windows. If you are outside, seek shelter in a sturdy building or vehicle.
