Ask HN: Why doesn't Google Weather not show duststorms?

I can't answer for Google, but I notice that www.windy.com has a dust mass layer:

https://www.windy.com/-Dust-mass-dustsm?dustsm,22.208,79.739...

Why are you looking for weather forecasts with a company that is specialized catering adverts instead of institutes that are specialized forecasting weather?

It 'doesn't not' show dust storms So that means it does show them?
