Floods can occur at any time. They are a real threat in the spring as a result of melting snow from a particularly snowy winter. They can occur in the spring through autumn months from an excessive rainy season. Whatever the reason, we are not really safe from floods. While we know we should flee to higher grounds and heed evacuation warnings; we also have to return home where our houses may be, at least partially, covered in flood waters. We need to be on the alert as to how flood waters can affect your health.
