Tropical Cyclone Laurence was named by the Darwin BoM yesterday (13th Dec) - the first TC in the Australian region for the 2009/2010 season. Warnings were issued in the 48 hours prior to its naming as the tropical low passed over the Top End and Darwin with damaging winds and flooding.
It's not the only TC at present. There are an amazing FOUR tropical cyclones active in the southern hemisphere. Mick near Fiji, Laurence, Cleo which regenerated east of Madagascar and an unnamed system in the mid South Indian Ocean. More details here:
