Parabolic ("dish") antennas should never need realignment, even after a hurricane. We can forget about that sad-sack satellite user that cable ads show wrestling a dish on the structural equivalent of a coat rack.
The reality is that properly installed microwave antennas are aligned just once. It's nearly impossible to budge an antenna after it's attached to a galvanized steel pipe and through-bolted to a solid foundation, such as an elevator penthouse or parapet wall. Industry standard mounts are rated to withstand hurricane force winds of up to 150 MPH.
While realignment should never be necessary, wind could be a factor in tower or monopole installations if the structure wasn't engineered for the wind load specs of your dish. The beamwidth of a licensed microwave transmission is especially narrow (~0.9-2.0 degrees) and so the tower must meet tight twist and sway tolerances. When in doubt, pay for a wind load study. Cost is about $1,500 to $2,500.
