Before a flood, it is important to be prepared by creating an emergency plan and assembling a disaster supply kit. During a flood, it is crucial to stay informed about the situation through local news and weather updates, and to follow evacuation orders if necessary. It is also important to avoid flooded areas, moving water, and to seek higher ground if trapped in a building. After a flood, it is essential to wait for authorities to give the all-clear before returning home, as well as checking for structural damage and avoiding contact with contaminated water. Additionally, documenting any damage for insurance purposes is recommended.
