65mph winds??? Wow, they were way off this time. It did gust above 30 mph a few times but nothing too bad. Dust was a little bit high in the afternoon but died before sunset. Seeing was...well, about as well as could be expected given the dust and wind, so not great, but not awful.
No problems tonight.
