A Severe Thunderstorm Warning is an alert issued by weather authorities when a thunderstorm in your area is producing, or is capable of producing, severe weather conditions. In the United States, the National Weather Service (NWS) defines a severe thunderstorm as one that includes:
- Large hail: Hailstones with a diameter of 1 inch (2.5 cm) or larger.
- Damaging winds: Wind gusts of 58 mph (93 km/h) or higher.
- Tornadoes: Severe thunderstorms can also produce tornadoes without warning.
When such conditions are detected by Doppler radar, observed by weather spotters, or reported by emergency management or the public, the NWS issues a Severe Thunderstorm Warning for the affected areas.
Safety Precautions During a Severe Thunderstorm Warning:
- Seek Shelter: Immediately move indoors, preferably to a sturdy building.
- Stay Away from Windows: Strong winds and hail can shatter glass, posing a hazard.
- Avoid Electrical Appliances: Refrain from using corded electronics to reduce the risk of electrical shock.
- Stay Informed: Monitor local weather updates through reliable sources such as NOAA Weather Radio, local news stations, or official weather websites.
It's important to note that severe thunderstorms can occasionally produce tornadoes with little or no warning. Therefore, remain vigilant and be prepared to take additional safety measures if a Tornado Warning is issued.
