Cyclone Christine

Cyclone Christine intensifying off the Australian coast on 29 December

Upon making landfall, Christine produced heavy rainfall across a large section of the West Australian Pilbara. In Roebourne, a total of 134.2 mm (5.28 in) was recorded by a rain gauge before the instrument failed, while the maximum daily precipitation total of 168 mm (6.6 in) was observed in Abydos North. Additionally, Port Hedland recorded 123.2 mm (4.85 in), Karratha 112.8 mm (4.44 in), while thunderstorms along Christine's outer bands produced three-day totals of 181.8 mm (7.16 in) in Broome and 137.2 mm (5.40 in) in Lagrange Bay. All mining and shipping operations were cancelled in Port Hedland, however no actual damage to mining infrastructure was reported.[3] Roebourne and Wickham bore the brunt of Christine's winds, with a maximum confirmed gust of 172 km/h (107 mph) recorded at Roebourne.[4] Both towns received significant damage and according to many local residents of Wickham, Christine was the worst cyclone in recent memory; several roofs were significantly damaged and many of the towns trees were uprooted and destroyed.[5] In Roebourne, roofs of many houses collapsed under the weight of water or were ripped off by wind gusts, while the whole town lost electricity for a short period.[5] Karratha and Port Hedland were spared any major damage, apart from minor flooding and wind-related damage. As Christine moved inland, flooding closed the Great Northern Highway north of Newman, however the town itself received 70 km/h (43 mph) wind gusts and only 25.0 mm (0.98 in) of rain.

An estimated 3–4.5 tonnes of iron ore was lost in exports across the Pilbara region due to Christine. Mining operations and shipments were suspended for three days, though most of the facilities sustained only minor damage if any.[6] Despite the storm, Port Hedland reported a record monthly export of 29.9 million tonnes in December 2013, with 28.5 million tonnes being iron ore. This surpassed the previous record set in September 2013 by roughly 300,000 tonnes.[7]

As the remnant low of Christine moved south-eastwards and into South Australia, it combined with a thermal low whipping up gusty winds and causing extreme heat across central Australia. Moomba recorded a maximum of 49.3 °C (120.7 °F) on the 2 of January, almost beating its former record high set the year before.[8] 70 km/h (43 mph) winds combined with the heat caused catastrophic fire dangers across the southern inland and a complete fire ban was issued for South Australia.[8] As the extreme heat moved east, temperatures of 48.7 °C (119.7 °F)[9] were recorded in Birdsville, Queensland and 49.1 °C (120.4 °F) in Walgett, New South Wales.[10] Further south however, Christine's remnants caused light showers and a cooler change in the Adelaide area, while isolated thunderstorms caused 42.8 mm (1.69 in) of rain to fall in Eucla, more than triple the areas monthly average.[11] Victoria and southern New South Wales also recorded light rain and a cooler change from Christine's remnants, with Melbourne reporting 4.8 mm (0.19 in) and maximum temperatures in the low 20 °C's during the New Years period.[12]

The name Christine was replaced with Catherine in 2014, but the name has not been confirmed as retired.
