Two tropical cyclones Marcia and Lam hit Australia on 20 February 2015. This is the first time that two cyclones have hit Australia at one time.
Tropical cyclone Marcia is a category five storm and it made the landfall at central Queensland and left a trail of destruction over Yeppoon and Rockhampton.
On the other hand Cyclone Lam is a category four storm which made landfall in the Northern Territory.
Earlier, in 1977 and 1986 also two cyclones had crossed Australia at once but they were not as severe as tropical cyclones Marcia and Lam.
Tropical cyclones are considered severe once they reach category three, with gusts of 165-224 kilometres (100-140 mph) per hour. Five is the highest rating, with gusts of more than 280 kilometres per hour and capable of wreaking widespread destruction.
