I've come across some more "interesting" design choices by the BoM for their new website.
Firstly rain observations are now grouped by hour, rather than showing individual readings, which in most cases was every half hour.
The new website no longer shows a running total for rain either, so you need to manually add up the hourly totals or check the high/low section for daily total (midnight to midnight of course)l.
I was told in no uncertain terms that this is intentional and they won't be reverting to how the old site worked.
Luckily for now the old site still functions the same as it did prior to the new site going live.
Weatherzone seems to still operate in the same manner as well, so some choices for now.
