Smoke rises vertically - Force 1 (calm)
Light flags extended - Force 3 (fresh breeze)
Small trees sway - Force 5 (strong breeze)
Resistance felt when walking - Force 7 (moderate gale)
There is more to it but it got me to thinking I should make my own observational scale of wind speed:
Tinkle of wind chimes - Force 2 (light breeze)
Garbage can falls on it's side - Force 4 (moderate breeze - it sits on uneven ground)
Benches by Ragnarok tip over - Force 6 (strong breeze)
Light at the top of the garden pole is flipped across the lawn - Force 8 (gale)
Like the Beaufort scale mine also has other specifications (e.g. Strong enough to rock the chairs on the deck; Strong enough to knock over the big rabbit scupture sitting on the septic cover; Strong enough to blow open the front door.) Best to stay out of the woods until the winds die down a bit - especially after a winter of heavy snows. Doesn't take much wind for 'dead men' to start falling from the trees.
