Quick Summary

A severe thunderstorm is defined by the U.S. National Weather Service as a storm producing a tornado, winds exceeding 94 km/h (58 mph), or hail at least 2.5 cm (1.0 inch) in diameter. These storms develop based on the meteorological environment in which they form.1

Supercell storms are the most intense type, characterized by organized, rotating updrafts and downdrafts that reinforce each other, leading to long-lived storms capable of producing significant wind and hail damage, as well as powerful tornadoes.1

Weather warnings are crucial short-range forecasts aimed at protecting lives, with particular efforts made to warn of hail, lightning, and wind gusts associated with severe thunderstorms.2
