Winds have definitely picked up. Without an anemometer, if I had to guess, I'd say it's a now a steady 10-15 MPH with some occasional gusts 20-25 MPH, out of the S/SW.

Went ahead and added a couple extra ratchet straps from my shelter frame to the truck's shackles, just to be on the safe side. If anything goes this time, it will be the fabric.
