It seems to only be possible to assert that there is a minimum amount of rain
In fact I need to assert that there is a maximum amount of rain. I would probably set this to 0mm - i.e. it must not be forecast to rain at all
This one thing unfortunately makes the alerts a bit pointless for me. I'm based in the UK, we get a lot of rain!
Currently I use UKV
However - switch to an overlay that is not UKV supported and then switch back to a supported one and you are now in ECM mode and have to remember to manually switch it back to UKV
This can be really confusing!
Please can we have a real default model option, which will always try to display overlay with that model first before using ECM
