Tropical cyclone brews off the Kimberley while freezing rain causes chaos in Quebec and Ontario
At the weekend a tropical low that was situated in the Timor Sea moved west-south-west into waters north of the Kimberley, Western Australia. Deepening as it moved, the low developed into a tropical cyclone on Sunday night that brought gale-force winds of up to 56 mph (90km/h) to the coast. Squally thunderstorms across northern parts of the region produced strong winds and heavy rain.
The tropical cyclone is forecast to reach category 3 by Tuesday. From Wednesday it is expected to turn south, prompting the Australian Bureau of Meteorology to warn that a significant risk of further instability could steer the storm south-east into central or eastern Pilbara, or western Kimberley. Given sea surface temperatures will be 30-32C (86-90F), the cyclone is expected to deepen to a category 4, with some models forecasting central pressure as low as 910hPa.
