The Weather
This weekend seems an opportune time to mention here at NoBMoB we now have a simple test (read: this may or may not work/be accurate) page relating to rainfall on various tracks we know and love:
This shows relative rainfall (ie. the scale is not calibrated in any particular way) graphs that are built from the BOM Rain Radar data.
Looking at this right now, Manly Dam and Ourimbah in particular have copped a lot of water the last couple days, probably best to stay away. Looks like Canberra tracks are nice and dry for those venturing down there. Lucky folk!

Rob, I like many use BOM to see what the weather is like just prior to riding but what a great idea to map the preceeding days/weeks rainfall history so as to get a better idea of the ground conditions.
You are not just a pretty face with a cute bike.

Rob, what do the different colours mean, most days seem to have several different colours and they don't seem to relate to rainfall volume?
Again, great work, please keep it up.
Ahhhhh... see, now I have to write an explanation. Briefly:
The colours are the same as BOM colours - look at their radar. Yellow/red stuff is rather heavy. Light blue is quiet light. The graph is stacked with heaviest falls on top. The height of each stack is proportional to the rainfall in that hour, with the colours helping you see how bad it was.
Through this you are meant to be able to see that a high blue bar means it rained for a long time, but not very heavily and the same height yellow means it didn't rain for long, but when it did, it was hard.
I'll try and graph by day over a longer period - weekend just past makes an interesting example, no?
That's the bee's knee's Rob... top work. It will come in very handy. Does it come from live BOM updates, or do you manually put the raw data together once per day? It looks like it would be pretty handy for places like Red Hill - that suffer a lot of water flooding.
If we can't get a sexy female reporter to do naked weather reports for us, I guess this is the next best thing
It's automagic of course
Rob,
Great data.
Allways helps to know how badly its gonna look like you've crapped in your shorts after a ride.
Where in BOM did you get the charts, there a great bit of info.
I've looked but can only find lists of the similar data(No Graphs).
Ahhhh... you won't find these charts on BOM or any place else. They are built by scraping the radar images and recording what rainfall intensities at reported at known locations. Then those values are graphed.
Given the weather lately, picked the right time to play with this, eh?
the current weather, you know to make us all appreciate your great work a little more.
