What is a severe storm?

Storms can comprise of heavy rainfall and flash flooding, damaging winds, lightning strikes and hail. Severe storms can last many hours and travel long distances, potentially causing considerable damage to homes and vehicles, and causing loss of power, isolation and flash flooding.

Severe thunderstorms, as classified by the Bureau of Meteorology, are storms that are likely to produce:

  • large hail measuring more than 2cm in diameter

  • wind speeds of more than 90 kilometres an hour, and

  • heavy rainfall conducive to flash flooding.

A severe storm warning will only be issued by the Bureau for storms that are likely to produce all three elements.
