Thank you for providing an example! Is it also possible to retrieve historical weather alerts? I have tried passing hourlyStart and currentAsOf but only current alerts are returned.

Thanks for confirming!

They are between 0 and 1 so its clear what the fields mean but more documentation or information about changes to the API would be useful...

I have the same issue for hourlyForecast, what is the maximum number fo hourly forecast that WeatherKit can return?
