Heavy rains due to La NiÃ±a conditions frequently cause home flooding in the Pacific Northwest. Heavy rains can occur throughout the year in the Pacific Northwest, so it’s important to know which company you can call for mold removal and water damage repair.
Flash floods , which are often caused by heavy rain, are the number-one weather-related killer in the United States. On the West Coast, heavy rain typically occurs in rainy season from November to April. They can tear out trees, turn boulders, and destroy structures. Flash floods can also occur from the collapse of a dam.
Levees and Dams
Levees and dams hold back water, but they aren’t foolproof. There are thousands of miles of levees on the West Coast. Some have failed in the past, and when they do they can fail terribly and cause serious damage that requires flood clean up on a very large scale.
When the ground freezes during the spring and winter, melting snow and rainfall cannot seep into the ground. Just one cubic foot of compacted snow contains several gallons of water. Once the snow begins to melt and spring rainfall arrives, it’s not uncommon for rivers, lakes, and streams to overflow.
Hurricanes bring high winds, heavy rain, and flying debris. Coastal areas are at the most risk for hurricane-related flooding, but hurricane rains and winds can still cause flooding hundreds of miles inland. Certain regions of the United States are particularly vulnerable to hurricanes, and fortunately the Oregon coast is not one of them.
