also most rain ever on one day. 120mm i think

Bizarre weather indeed. Fortunately the rain is not expected to be as bad as the previous 24 hours.

130mm of rain poured on Melbourne and there is still heaps to come.

send some of that cold Melbourne weather up to Brisbane thanks as Im sick of those hot and humid 30+ degree days.

That dump increased reservoir levels by .4%.

Cardinia got 100mm, Upper Yarra 73mm, Sugarloaf 120mm, Thomson 85mm.

We must be in some winter pattern.

Brisbane is currently warm and very dry - the humidity has basically vanished with the thunderstorms last night.
There are dry warm westerlies blowing in dust from somewhere over NSW & Southern Qld. Aparently in some places out west visability is down to just 50m.

Wierd weather.

^ We are! This is very rare. Caused by a Low Pressure system which is in the same place as it is normally in winter.

Melbourne Weather last night actually came from the East! Very very rare, most stuff comes from the South/West.

This time of year most stuff for us comes in from the North East - Coral Sea and is humid and moist. Well I can't complain anyway as the weather here is great;)

BTW its interesting that the Yarra is flooding in the city - a strong south wind can actually push water up into Hobsons Bay and into the Yarra. I understand that just wind action on the bay can push the height of the river up in the city by more than 80cm - combine that with heavy rain and you have a problem. (I learnt that on a yarra ferry trip once)

Also of interest is the that you guys had close to 140ml of rain - in Brisbane that wouldn't be a problem because the city is designed for that type of rainfall but in Melbourne its a problem because the city is not designed to take that much rainfall. Time to start redesigning our cities for the freak weather conditions that might occur due to global warming.

with respect Jayt. thats the second you've mentioned that in recent memory. and to put it simply it's obsurd. most of your queensland collegues disagreed with you and stated if you had 6 inches (150mm) of rain in less than a day there would still be flooding probelms. so please dont start this shit again... 'oh we have better drainage in queensland'... for christs sake you're such a bore.

most drainage systems are designed to handle upto a 1in50 or 1in100 year storm, and given that more rain fell in one single day than on any other day in Melbourne's history, suggests this was a very major storm. so please do us all a favour and get you hand off it.

How could you say that? I would never be sick of them!

Not sure what facutal evidence you have for this statement, but it is an interesting point you raise. I guessing the drainage for most of our major CBDs are based on systems "designed" in the 1800s. Imagine the logistics of re-routing stormwater in a CBD environment... :runaway:

Although there would be flooding if Brisbane suddenly got 120mm, I'd say it wouldn't be as extensive as it was in Melbourne. For example we had 102mm in 24h last march, which is obviously less, but there was no major flooding. I believe there were periods in 2002 where we got more rain larger amounts of rain but the BOM records don't go back that far.

Truthfully the onlytime I've ever seen any flooding of streets was a few years ago when we got over 200ml in 48 hours.

There was that afternoon back in March 2002 when the entire metro area got more than 300ml in 3 hours - it flooded then but only on major creeks, there were no other problems other than that. The stormwater drains up here are huge and can handle tropical downpours that would flood any other city.

The simple fact is that around Brisbane there is much more water available in the atmosphere. In Melbourne a one in a hundred year rain event might be 100mm in a day. Here it would be probably more like 500mm in a day. I know we get 100-200mm or more in a day reasonably regularly, as in around twice a year. It will cause local flooding depending on area, but nothing significant. The two biggest rain events I remember were when I lived on the Sunshine coast. They were around 500mm in 6 hours (1983), and 900mm in two days (1992). They both caused fairly extensive flooding.

IT is safe to say Melbourne is a Dry city where it really doesnt rain all that much.

No its about 1/3 that of Brisbanes - its just spread out more over time. Lots of drizzle instead of heavy rain. Sydney gets even more rain than Brisbane!!

jt

Therefore its dry in comparison but rains on roughly 140 days a year which again is the same as Sydney.

i remember that day but it was 2001. i was playing footy and the game got called off coz of lightning. lucky coz the creek behind flooded the field. we were caught in a 3hr jam of traffic. every bridge was under water. i remember that zupps aspley lost 11 cars that were swept into the creek.

heres a link for that day.
