Blowing From and Blowing To are two different conventions for describing wind direction.
- Blowing From indicates the direction that the wind is coming from (e.g. a West wind is blowing from West to East)
- Blowing To indicates the direction that the wind is going to (e.g. a North wind is blowing to North from South)
