The official site of the NFIP, Floodsmart.gov, has published some bullet points covering several types of spring flood events. We at Flood Flaps thought it would be helpful to pass along their info.

How Prepared Are You for Spring Flooding?
Warmer spring weather brings everything from heavy rain to snowmelt, which can increase your risk of flooding. Get the facts, know the risk, and take action to prepare before seasonal events strike.
Heavy Rains
Many areas of the country are at heightened risk for flooding due to heavy rains. This excessive amount of rainfall can happen anytime throughout the year, putting your property at risk.
Storms over the Pacific Ocean bring heavy rains to the western United States between the months of November and April. Spring rains in colder climates can lead to flooding when the still-frozen ground cannot absorb the water. And summer months often bring heavy rains to the eastern and southern United States as warm air and moisture from the ocean move inland.
Cresting rivers, backed-up storm drains or saturated ground can cause significant, widespread floods during these times.
Prepare For Heavy Rains
1. Review your current homeowners insurance policy and become familiar with what is and is not covered, as damage due to flooding is typically not covered.
2. Call your insurance agent to purchase flood insurance for your home (and business) and its contents.
3. Make a flood plan and plan evacuation routes.
4. Itemize and take pictures of possessions.
5. Keep valuable items and family heirlooms on the upper floors of your home or building.
