Looking at your graphic, the three walls shown (in my garage) have the broken windows. The front has 2 metal doors. I was thinking since there are three openings, the wind wouldn’t have much chance to go upward, it would pass through horizontally.
Hopefully I can get someone by tomorrow to board them up.
Never underestimate wind turbulence and uplift, which causes building failure. Board up those broken windows. If there are a lot of trees in close proximity to your home, board up your intact windows too.
