Difference between a special weather statement, a severe thunderstorm watch and a severe thunderstorm warning
Environment Canada issues a special weather statement when there is potential for an event that may approach the warning or watch criteria.
A severe thunderstorm watch is issued when there is a good chance of severe weather developing.
A severe thunderstorm warning has four elements: winds greater than 90 km/h; hail greater than 2 cm; flooding rains; or a tornado.
