Click on the red play button (bottom left) of the map, it will then show the forecast for rain and thunder for the next week. If you look at the marker on the locations it will give rain in MM that will fall

You can also click the same red play button to pause on a time

Also, if you click on the top right of the map where it says rain/thunder, you can change the forecasts to virtually anything that you want, temp, wind, snowfall etc

The map below will show if there is any heavy rain due to fall in the next 24+ hours, I have found it to be quite accurate
