Flooding rains in NSW December 2009

Sunday, December 27th, 2009

Finally heavy rains have drenched drought stricken areas of NSW with well over 100mm of rain falling in some regions and more predicted. Some rivers are in flood with a potential flood alert for other rivers. The Hunter Valley and the North West Slopes as well as parts of north eastern NSW are also to be affected by heavy rains.

This all is the result of Tropical Cyclone Laurence. That severe tropical cyclone made all the way inland with continued tropical cyclone warnings which is very unusual.

Tropical Cyclone Laurence

Monday, December 14th, 2009

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:

December heat wave and bushfire weather return

Tuesday, December 8th, 2009

Bushfires and extreme heat have surprisingly returned. It certainly amazes me how low temperatures over western Queensland a week ago and also parts of the Northern Territory have once again allowed for the heat trough and ridge to set in extending to coastal NSW once again. Furthmore, the wet season has barely made any impact on the Northern Territory or over most parts of northern Australia for that matter! The latest models consistently show extreme heat covering at least a quarter of the continent over  the interior. Basically, this excessive heat must give way to an extensive monsoonal trough and ample rainfall as well as an extensive tropical cyclone season.
