Severe thunderstorm watch

A severe thunderstorm watch SAME code: Severe thunderstorm watch is a statement issued by weather forecasting agencies to advise the public that atmospheric conditions in a given region may lead to the development of severe thunderstorm watch thunderstorms within or near the region over several hours. The criteria for issuing a watch varies from country to country and may also include torrential rainfall and tornadoes. A watch may also be issued several hours ahead of the arrival of a mature and organized complex of storms, severe thunderstorm watch, such as a mesoscale convective system. A severe thunderstorm watch, like a tornado watchis not to be confused with a warning.

A severe thunderstorm warning SAME code: SVR is a type of public warning for severe weather that is issued by weather forecasting agencies worldwide when one or more severe thunderstorms have been detected by Doppler weather radar , observed by weather spotters , or reported by an emergency management agency, law enforcement, or the general public. Unlike a watch, a warning is issued to areas in the direct path of active severe thunderstorms, that are expecting a direct impact typically within an hour. Severe thunderstorms can cause property damage and injury due to large hail , high winds , and flooding due to torrential rainfall. The exact criteria to issue a warning varies from country to country. Most forecasting agencies have similar criteria, but some agencies, such as Environment Canada , also include high rainfall rate. Others may instead issue a flood advisory or a flash flood warning in that case. A severe thunderstorm warning indicates the warned area is in impending danger from hail or wind speeds meeting warning criteria as well as from lightning and hydrological impacts associated with the storm cell.
