It marks an area which experienced some unusual weather activity in the early hours of Sunday morning on the 24th of February 2013. Reported as the South Coast being hit by a "family of tornadoes".
Experts from the Bureau of Meteorology believe ‘‘a whole family of tornadoes’’ hit the region early Sunday morning, with four separate twisters now reported.
Attention focused on serious property damage in Kiama in the immediate aftermath of the storm, but there are also tell-tale trails of destruction at Gerroa, Jamberoo and Albion Park Rail.
Andrew Treloar, the bureau’s manager of weather services NSW, toured the region and confirmed damage in Kiama and Gerroa was the result of tornado activity.
He said the Kiama tornado was likely a category F1, or moderate, on the six-tiered Fujita scale of tornado intensity, with F0 the least intense and F5 the most destructive.
‘‘The system down here [in Gerroa] was even stronger – in our preliminary assessment, at least an F2. There’s no doubt in my mind now that we’re seeing tornadoes.
‘‘There seems to have been a whole family of tornadoes spawned by this weather system.’’
The F2 rating is for ‘‘significant’’ tornadoes, with wind speeds of between 181 and 252km/h
Mr Treloar examined the pattern and extent of damage to the region with the bureau’s manager of severe weather services, Michael Logan. - illawarramercury.com.au
