Several large wildfires in the western United States have dramatically changed the landscape and ground conditions, resulting in fire-scorched land that can lead to flash floods and mudflows under heavy rain. Experts say that it might take years for vegetation, which will help stabilize these areas, to return.
In cold climates across the nation, heavy rain sometimes follows heavy snow. The frozen ground cannot absorb the rain-soaked snow pack, so flooding occurs.
Along the Atlantic Coast, nor'easters can bring heavy rains, snow, and wind-driven waves that can lead to flooding and beach erosion.
Be prepared! Purchase flood insurance for your home (and business) and its contents, take an inventory of your belongings and make an emergency plan for you and your family.
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.
