Tropical cyclones, heat waves, storms and snow! January 2010

Friday, January 22nd, 2010

As two tropical cyclone warnings are issued up north – Tropical Cyclone Magda and now ex-tropical cyclone Neville – in contrastĀ heat waves and scorching the south of the continentSydney’s west experiencing 3 consecutive days of 40C or higher temperatures. Lucky the recent rains have made the forests and fields green again that bushfires are not a major threat.

And then of course snow fell during a brief cold snap that passed over southern Australia namely Victoria and southern NSW producing snow over the highlands of the Snowy Mountains. What a month. Now back to the 40C heat!

Incidently, following the two severe storm events prior to Christmas including the Singleton hailstorm, early January was an active period for severe thunderstorms with a few explosive thunderstorm events intercepted.

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 asĀ 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.

Flooding and Tropical Cyclone maps

Tuesday, April 14th, 2009

Since your past post, there has been more flooding. The events you refer to were extraordinary and follow flooding in February. Now another flood event! And in all this Victoria continues deep into drought. I guess such contrasts are not uncommon in Australia but this drought in Victoria has been long lived with few short breaks.incredible multiple bolt

The work you did on the tropical cyclone maps and since then the tropical cyclones main web page has added fresh looks and ideas on there well worth investigating. Well done on all you have done and I understand the immense amount work that goes into such projects.

Finally, I guess we are looking at the last month for Imelda’s pregancy and weekly visits to the hospital for the usual check ups. The scans at least show nothing abnormal and the weights are to be expected. Life will change with that birth and the added responsibility that comes with it!

Haven’t much chasing lately. The last chase was when I got this lightning shot across the road:
