Weather F215

Part of the met office aviation briefing service is the F215 UK low-level forecast chart. To get to the F215 you will need to sign up/register with the met office aviation briefing service. This is free just google “met office aviation briefing service”. Once you have access navigate to Briefing Charts and then Significant weather (Low Level) % Spot winds. Over on the top left side, you will see F15 select the time frame.

I believe most explain itself, let’s select zone A and break it down.

Let’s just focus on zone A
