Be Prepared – Protect Loved Ones  


What is a Flood? 

Floods are the most common and widespread of all natural disasters—except fire.  A flood is defined as an overflowing of water onto land that is normally dry.  Flash floods can take only a few minutes to a few hours to develop. 

Floods can take several hours to days to develop.  A flood watch means a flood is possible in your area.  A flood warning means flooding is already occurring or will occur soon in your area.    

There are steps that can be taken before, during, and after a flood to protect your family and pets and keep your property losses to a minimum.  The guidelines listed below can help your family prepare for an emergency.
