The Bureau of Meteorology (BoM) has updated its weather app – and it’s caused a lot of confusion among users.

The BoM has changed the way it is reporting rainfall through the app, it says because of how often rainfall information was misinterpreted.

Previously, if the BoM listed a 70 per cent chance of rain, and listed rainfall at between one and three millimetres, people often interpreted that as a 70 per cent chance of between one and three millimetres of rain.

But apparently this was the wrong interpretation. What that reading actually meant was that there was a 70 per cent of any rainfall happening at all (which may be less than one millimetre), and a 30 per cent chance of more than three millimetres of rain.

Clear as mud, right?

The BoM is looking to avoid this confusion by making the forecast a bit clearer by providing a range of possible rainfall outcomes for a given day.

For starters, BoM has got rid of a value for the chance of any rain falling as it was causing too much confusion.

The app now gives three rainfall values, one for 75 per cent (high chance), 50 per cent (medium chance) and 25 per cent (lower chance).

So for example, if the BoM app listed a rain range of 10-20mm for a day, it was also break it down further into a high chance (75 per cent) of at least 10mm of rain, a medium chance (50 per cent) of at least 15mm and a low chance (25 per cent) of at least 20mm.

The aim was to clear things up, but they may have actually made things worse.

What are your thoughts on how the BoM is now reporting rainfall?
