If you were right here, right now, then I think you would know what JB means
I don't know where you live or if you know this part of the world, but if you are sat up here on the side of the North Sea, then you would know that there is no such thing as 'wind direction'.....The wind hits you here there and everywhere....It takes effort ( mentally and physically ) to even stay on the left hand side of the road. It's too easy to say 'stay at home then' unpredictable is the name of the game. I have lived here for over 50 years and it still catches me out.
