Après le deluge

This is the rainfall in Adelaide today (time in the extreme left column, cumulative rainfall in millimetres in the extreme right column).

The chart tells a story. Between 3pm and 3.20pm, we got about 4mm of rain. Then from 3.22pm to 3.30pm, we got 7.6mm, and from 3.30pm to 3.53pm, another 8.6mm. That’s 16.2mm, or about 2/3 of an inch – a lot of rainfall in just 30 minutes. Even in wet New Zealand, that would be a huge downpour.

“Well, what of it?” you might say. “Surely you welcome rain in Adelaide?”

Indeed we do. But that half hour of heavy rainfall started at about 3.20pm, exactly when school gets out.

When the ducklings and I got home, with sodden shoes and school bags and raincoats, I made them hot chocolate.

  1. It can rain like that in Oklahoma. Especially in the spring. There have been days, I think, where we’ve gotten four inches of rainfall–maybe as much as an inch an hour. Hot cocoa seems to be exactly what is called for. And by the way, you are welcome for the link.

  2. And it was wonderful. Thunder, lightning and the roads awash. And more forecast for today. Bring it on.

  3. Here it is raining red dirt. Someone told me today that she had been talking to a bloke who drove from Adelaide across the Hay plain (in NSW) and it rained mud all the way. I don’t know whose top soil it is, but they have lost a lot of it. I’m just glad I didn’t have any washing on the line.

  4. I’ve just been looking at a picture of Canberra hazed out by dust on the ABC site. It took me a moment or two to work out that the shot looks down Anzac Avenue towards lake Burley-Griffen, except that the lake has virtually disappeared.

    It must be very hard for people with asthma or other breathing difficulties.

  5. The thing about the end of a a dry spell is the sudden realisation that the roof is not as you thought it was – it happens even in wetter Sydney. Do hope it didn’t happen to you. And the 3,20pm shower – that’s Murphy’s Law (my fave Oz expression).

  6. Yes. It’s a natural law. We should add it to Hobbes’ state of nature, which he derives from various natural laws that he has dreamed up.

    “Life in the state of nature is solitary, poor, nasty, brutish and short, and wet.”

  8. The formalized statement of Murphy’s law is “The perversity of the Universe tends to a maximum”.

  9. It doesn’t rain in Australia. It floods. I thought our 10mm in 30 minutes yesterday was bad, but that’s worse.
