The weather report

Brisbane is having the cyclone you have when not having a cyclone.
It is currently very windy in the part of Brisbane where I live, which is not near the coast.   Funnily enough, on the evening news, all the reporters on the coast seemed to standing in calmer conditions.  

I hope it calms down in the suburbs soon...

Update:   It's gone 11.30pm and it's still a bit worryingly windy.   I see it's been gusting up to 90 kph earlier this evening, so its not just my imagination. Here are the BOM weather observations:

Update: Apart from a couple of leaks around windows which haven't happened before, everything was OK at home. Haven't even lost power.

As a child in the 60's and 70's, small-ish cyclones heading down the Queensland coast towards Brisbane were more common than these days, but my recollection is that they tended to peter out as a cyclone usually around the Sunshine Coast. Sure, they could turn into a rain depression, but I don't recall much in the way of wind in the suburbs. That's what made this ex cyclone unusual - the widespread wind across the city that started late yesterday and didn't end until late this morning.

The most remarkable video from this event which I saw on a News Ltd website this morning has turned up in several Youtube accounts. If you haven't seen "Surprise car", you ought to. (I think this happened up at the Sunshine Coast.)

As to how bad the flooding will get in Brisbane tomorrow - it seems all very much guesswork.  It seems that one small area near me might be affected again, but I am hoping the modelling is erring on the pessimistic side.  We will see.

Of course, there are parts of Queensland doing it much, much worse (especially Bundaberg, which appears to be facing an all time record flood.)

Interestingly, until this rainfall started in Brisbane, the city was having an exceptionally dry January.  Not sure how the figures will look now.  It did seem to be illustrating what a climate change paradigm of swings from one extreme to another might look like, and it's not pretty.   As I suggested after the 2011 flood, if climate change means one in a 100 year floods start happening (say) once a decade, it's going to be a change of big economic consequence.
