Storm Spotters Australia

TORNADO INFORMATION POST

I have noticed a site (I use that term loosely) referring to the Tornadoes that took place in South Australia and refering to them and their associated damage in the EF Scale or The Enhanced Fujita scale (EF-Scale) rates the intensity of tornadoes in the United States and Canada based on the damage they cause.

For the correct information here in Australia we DO NOT use the EF Scale we still use the Fujita F-scalewhich.
Tornadoes are ranked using the estimates wind speed based on the extent and severity of damage.

"Strong to gale-force west to south-westerly winds averaging 50-65 kph with gusts about 90-100 kph are expected to develop behind the front during Wednesday," a bureau statement said.

"These winds may cause damage to trees and property.

"Following the front, an intense low pressure system will move across the Bight towards the SA coast with strong gale-force winds impacting western parts.

Weather fronts

Weather fronts mark the boundary between two air masses, which often have contrasting properties. For example, one air mass may be cold and dry and the other air mass may be relatively warm and moist. These differences produce a reaction in a zone known as a front.
