Local authorities, employers, councils, property and business owners have a responsibility to ensure the health and safety of others.
In the case of the recent Storm Eunice, warnings were provided of the incoming storm, therefore where persons have taken steps to reasonable prepare for the storm and protect against damage, they may be able to defend a claim, if one was bought.
If you took a risk, went out during the storm and suffered personal injury, the other side are likely to allege that you are partially to blame for the injury as you failed to take care of yourself. If a claim was bought that would seek to apportion and level of contributory negligence to you.
