Heavy Rain causes local flooding

Earlier this afternoon on the Southern Tablelands near Wingello I experienced a rather nasty left mover storm which dumped around 60mm of rain in 30mins which resulted in some local flooding.

Southern Highlands Chase - 22/12/14

Evening followers, Emma has been hard at it again with the warning updates. I had a bit of a chase earlier this afternoon around the Southern Tablelands which left me feeling frustrated.

Today consisted much of the pop corn type of storm which pop up last about 15-20mins and vanish just as quick.

The storm of the day had to be in the pretty much unchaseable area of Arulan NSW. 62mm of rain fell in just 30 minutes and I would put that storm down as a possible super cell.

Lightning - What's it all about....

Lightning is an electric current within a thundercloud in the sky. Many small bits of ice bump into one another as they move around in the air and all of these collisions create an electrical charge, which then causes the clouds to fill up with these electrical charges, the positive charges form at the top of the cloud and the negative at the bottom, and seeing as opposites attract it causes a positive charge to build up on the ground beneath the cloud.

Magical South Coast NSW

Well as Chris mentioned last night I went storm chasing to the far South Coast last night.

I anticipated a lightning show with a vigorous southern ocean front approaching the region.

Here's a photo before I raced closer to the storm. The storm was so incredibly active with non stop flashing. I will also post a video up when I get the chance.

CLOUDS! - What are they and how are they formed?

Clouds form when warm air rises and expands and cools forming tiny droplets of water or ice crystals that settle onto dust particles in the atmosphere, the dropletes are so small (a diameter of around 100th of a milimeter), so that means each cubic metre of air will contain 100 million droplets. Clouds will either be composed of either ice or water droplets, depending on the height of the clouds and the temperature of the atmosphere, because the droplets are so small they can remain in liquid form in temps as low as -30C.

Far South Coast Lightning Show

This evening the 18/12/14 storm chaser Michael Keene and fellow SSA Team Member was lucky enough to take up position south of Merimbula.

He was greeted with a rather mundane experience at first but as patience persisted he was lucky enough to experience an amazing CC (Cloud to Cloud) lightning show.

He would estimate 100 flashes / Min. Sadly after dark scud cloud moved in a destroyed most of the view.

He was able to capture a few CG's (Cloud to Ground)

Site Issues

Hi All, Just to let you know we are having some technical issues with our warnings feed. Please check our Facebook page or http://www.bom.gov.au/australia/warnings/index.shtml for current warning information.

I hope to have this fixed asap.
**QUICK UPDATE - I have the feed working on the main page though it is running a little behind, it is working in the weather warnings page but not posting in order. The last post is the newest.

Still working on a fix for this at present.
