Cyclone Heidi

Severe Tropical Cyclone Heidi was a small and strong tropical cyclone that struck Western Australia in January 2012. The seventh tropical low, third tropical cyclone, and second severe tropical cyclone of the 2011–12 Australian region cyclone season, Heidi developed from a tropical low that formed to the south of Indonesia on 9 January, before strengthening into a Category 1 tropical cyclone on the following day. Tracking southward towards the Pilbara coast in a favourable environment, Heidi rapidly intensified and attained Category 3 severe tropical cyclone status on 11 January. After making landfall at peak intensity later that day with estimated winds of 150 km/h (95 mph), Heidi rapidly weakened, dissipating over Western Australia by 13 January.

In advance of Heidi's arrival, the Port of Port Hedland, offshore and coastal oil rigs and iron mines were shut and workers moved out of the area. Alerts were issued for much of the Pilbara coast, and the Port Hedland International Airport was shut. Heidi dropped heavy rainfall across the Pilbara and West Kimberley regions in Western Australia, with a maximum accumulation of 168.5 millimetres (6.63 in) being reported at Pardoo Station. These heavy rains lead to minor flooding on roads in the region. In addition, strong winds knocked out winds and caused major power outages in South Hedland and Wedgefield. Overall, Heidi caused only minor damage and no deaths; nonetheless, the name Heidi was later retired from the rotating list of storm names assigned by the Bureau of Meteorology.
