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.

Storms NSW Storms Floods – Record Bourke Rainfall from severe storm

Monday, February 16th, 2009

Hi Jimmy, the floods continue in North Queensland though also managed to spread to NSW over the weekend as an upper low, surface trough and fairly strong high combined. The upper low over northwest NSW was the most extraordinary part of the event. It managed to produce hailstorms then near-stationary flash flood thunderstorms over night Friday into Saturday 14th Feb. Bourke recorded almost 200mm of rain, with the daily rainfall record dating back to 1874 broken. I did hear some unofficial reports of close to 400mm of rain in that area – a region which only averages that much a year! A small low and trough persisted off the Southern Queensland and Northern NSW coasts during Saturday and Sunday with many centres picking up between 150 and 250mm of rain. Minor to moderate river flooding is still occurring between Bellingen and the Hunter. I was on SES duty at Richmond Tweed on Saturday but the threat passed to the south later in the day. I measured 70mm over 36 hours at home.
