… it pours!
The long term average rainfall for December in Adelaide is just over 28mm. Today we have gotten nearly twice that (so far), with most of it falling in just one hour. Here’s part of the record from the Kent Town observation station (for non-Adelaide people, that’s just outside the CBD).
(Description: Weather observations chart. Various columns: time at extreme left, cumulative rainfall at extreme right.)
There’s a special story in this rainfall record. Time is on the extreme left, and rainfall on the extreme right. Up until 3pm today, there had been no rain. By 3.30pm, 27mm had fallen, and by 3.59pm, we were up to 42mm of rain.
Exactly when all the children were getting out of school. Yes, this *has* happened before.
