If there is something we learned about Hurricane Katrina, it was that the majority of the damage was caused by the flooding and not the impact of the hurricane. Southern Arizona monsoon season starts mid June and ends around mid September. The process starts with the warm and dry weather of May and June. Our rainy season brings in thunderstorms and torrential rain. The storms tend to last about two hours and temperatures are known to drop down to the 70's.
Hazards associated with torrential rains include flash floods, stream flooding, and landslides. Changing weather patterns, erosion, and development can affect floodplain boundaries too. Special Flood Hazard Areas represent the area subject to inundation by 1-percent-annual chance flood. Structures located within the SFHA have a 26-percent chance of flooding during the life of a standard 30-year mortgage. Federal floodplain management regulations, and flood insurance is mandatory if you live in a high-risk area when you have a mortgage from a federally regulated or insured lender. Following information will help you identify your flood risks and guide you through mitigating your water damage and saving your possessions.
