Get your TAFs right
G'day chaps,
I see a lot of people (including myself) looking at 'PROB30s and PROB40s' on their TAFs and remarking, "30% probability of this, 40% probability of that..." etc etc.
However I was recently enlightened/corrected to believe that this is in fact nonsense and that a '30' can be thought of as 'low probability' and a '40' as 'high probability'.
This does seem more logical for two reasons I can think of, 1) Why is it ONLY ever '30' or '40', and 2) A forecast cannot generally be absolutely certain of the future weather anyway, let alone label it with a quantitative value in the form of a percentage.
Any ideas?
Cheers, Jack.
