What are the disadvantages of flood shelters?

Flood shelters can often be underfunded and poorly constructed, making them inadequate for severe weather events. They may also be located in areas that are not easily accessible during flooding, limiting their effectiveness as safe havens. Additionally, if not properly maintained, shelters can become overcrowded or lack essential supplies, leading to uncomfortable and unsafe conditions for evacuees. Lastly, reliance on shelters can discourage long-term planning and risk mitigation in vulnerable communities.
