Storm Spotters Australia

TORNADO INFORMATION POST

I have noticed a site (I use that term loosely) referring to the Tornadoes that took place in South Australia and refering to them and their associated damage in the EF Scale or The Enhanced Fujita scale (EF-Scale) rates the intensity of tornadoes in the United States and Canada based on the damage they cause.

For the correct information here in Australia we DO NOT use the EF Scale we still use the Fujita F-scalewhich.
Tornadoes are ranked using the estimates wind speed based on the extent and severity of damage.

Poor South Australia at present is getting smashed, please check warnings on the BoM page regularly.

"Strong to gale-force west to south-westerly winds averaging 50-65 kph with gusts about 90-100 kph are expected to develop behind the front during Wednesday," a bureau statement said.

"These winds may cause damage to trees and property.

"Following the front, an intense low pressure system will move across the Bight towards the SA coast with strong gale-force winds impacting western parts.

Weather fronts

Weather fronts mark the boundary between two air masses, which often have contrasting properties. For example, one air mass may be cold and dry and the other air mass may be relatively warm and moist. These differences produce a reaction in a zone known as a front.

14/09/16:
As per yesterday we will see scattered thunderstorm activity become more widespread particular in NSW, these thunderstorms will mainly stay west of the divide which is sad news for those of use who live on the coast.
Peak time will be mid to late afternoon.

However I would not rule out an offshore rumble or too late afternoon/evening. 10-15% chance now.
There is the chance again of Severe thunderstorms tomorrow with damaging winds, heavy rain and large hail all possible again mainly on the western ranges and northern VIC.

13/09/16:
Good Morning, Well another wet one for Victoria with a low pressure system developing over eastern SA/Western VIC today.

Heavy Rainfall, Flash Flooding and Damaging Winds possible.

Widespread rainfall totals of 20 to 50mm are forecast with higher totals particularly under under thunderstorms which develop are quite possible as is small hail.

Scattered thunderstorms possible for Eastern VIC also.

South Western NSW looks to cope a few MM too with up to 20mm possible.

Hi Followers, To make things a little easier for us and everyone from now moving forward we will not be posting each warning.

Official Warnings can be found at:
http://www.bom.gov.au/australia/warnings/index.shtml

We will be doing our own "heads up" or observations in posts on the page as normal. As storm seasons approaches this will allow the most relevant information to be available on our page whilst also not bombarding your news feed.

Well a ECL is forming just off Grafton this afternoon as rainfall of 60mm so far has caused minor flooding in area's like Kempsey in Northern NSW.
Strong winds are battering the NSW coastal areas with an average of 60-80km/h gusts as show on the Weatherzone Map.

No doubt the Bureau of Meteorology will up date its warnings accordingly this afternoon. We will pass them on when they do.

In the meantime please take it easy on the road's in the NE where it is raining and for the rest of us please secure loose items in the backyard.

The Bureau of Meteorology has released a warning included below of the up and coming Severe weather to affect parts of the Queensland coast and NSW coast. NE NSW is set to bare the brunt easing the further south you go.

As is typical of a East Coast Low event it will depend very much on where the low forms as too who gets the most rainfall and wind. 24 hour totals of in excess of 100 mm are possible, with winds up to 100km/h.

Details of the warning are below:
