Severe Thunderstorm Warnings Explained
It's not an unusual outcome on a hot summer's afternoon to experience the cool relief of a thunderstorm; however severe thunderstorms can cause huge impacts to property, and can be life threatening. Severe thunderstorms can be highly localised or widespread. Roughly 10% of thunderstorms are severe but can account for 90% of the damage produced.
A severe thunderstorm is defined by the Bureau of Meteorology (BOM) as one which produces:
Hail, diameter of 2cm or more; or
Wind gusts of 90km/h or greater; or
Flash flooding; or
Tornados or any combination of the above.
Most thunderstorms do not reach the level of intensity needed to produce these dangerous phenomena, but they all produce lightning which can cause damage, injuries or in very rare cases, death. Severe Thunderstorm Warnings (STWs) are issued by the BOM either where a strong thunderstorm is reported or there is evidence and is expected to continue. STWs are issued every 3 hours, or for more detailed city warnings these may be issued every 30-60 minutes.
Up to date warnings are issued via BOM, broadcast and social media. The Early Warning Network site features several handy features to access up to date warnings, including smartphone applications and SMS/Email alerts. Be sure to register.
