Apparently tomorrow we have a 100% chance of no rain. Seems like a strange way to describe it. So when we have a 100% chance of rain I assume it’s going to be expressed as 0% chance of no rain! 
Whar are they thinking? What’s wrong with the old ‘x% chance of rain tomorrow’. That makes a lot more sense to me.

Is it strange? It depends on what the question is.   If the question is what the chances are of it not raining (so I can go out in the boat or for a bushwalk), oh, 100% great or what are the chances that rain will impact my activities  (0% -great). Both of these are logical.   I think the complaint is that they used to do it this way, and now they are doing it a different way.  I don't think many people would be confused and not understand what it means.

Tghat flags the use of AI in creting the website.

Just looking at the how the chance of rain is expressed.

 

In my location next Friday at 5am

There is: 

a 50% chance of 0mm (50%  it won't rain)

a 25% chance of at least 1mm

a 10% chance of at least 3mm

 

On the old forecast site, it just gives a 75% chance of rain on that day.

 

I can't see why anyone would be baffled by this.

The chance of rain does have some science behind it.  There are also different ways of expressing the same prediction. For example, there is an 80% chance of marital relations with Mrs Octave tonight or a 20% chance of not getting any; it means the same thing.

There is always a conundrum in communicating information to a varied public. Someone will always be unhappy. In Britain, there was a campaign in 2011 to do away with percentages and use narrative terms like "slight chance" and "scattered"
