When I got home yesterday we moved everything in the backyard over to a fence, tied or strapped stuff to the fence, and/or weighted it down with other stuff. I think everything should be fine. We had 60+ mph winds during a storm about 3 weeks ago, with 80mph gusts reported in some places, and we didn't have any major problems other than that large tree branch... Here's hoping that the rest of that tree is in good enough shape to withstand this coming storm.
Yesterday was spent updating a large number of 'reserve' computers in preparation for the emergency center's activation - we may not need them, but its better to have them stacked in the corner ready for use than to be frantically reconfiguring and updating when they are needed immediately.
