I'm not sure insurance would class this as your fault anyway - assuming you parked normally then isn't this the wind's fault and anyone who suffers damage needs to claim off their own insurance? I'm sure I heard something similar when someone's car door was blown into another car by a gust of wind - the third party had to claim on their own insurance as the person in the first car hadn't been 'negligent' in the way they opened their door. Could be wrong though.
