A fifty percent chance of more rain?
 

Improving chance of rain, says weather bureau

Wednesday, 23/06/2010

The weather bureau has revised its forecast, to increase the likelihood
of rain across Australia over the next few months.

A month ago, there was only a 30 to 40 per cent chance of getting more
rain than normal. Now the bureau's latest season outlook says it's about
a 50 per cent chance, or 65 per cent if you live in north Queensland.

The weather bureau says it's down to a changing climate and shifting
seasons, noting that for eastern Australia the last 13 Mays in a row
have had below average rainfall.
Why dont they just say they dont know.
A fifty percent chance is either way...
They could say "we have no idea".
