===Flooding===
Occasional severe flooding is experienced in the United States. Significant floods throughout history include the [[Great Mississippi Flood of 1927]], the [[Great Flood of 1993]], and widespread flooding and mudslides caused by the 1982–83 [[El Niño]] event in the western United States. Flooding is still prevalent, mostly on the Eastern Coast, during hurricanes or other inclement weather, for example in 2012, when [[Hurricane Sandy]] devastated the region. Localized flooding can, however, occur anywhere, and mudslides from heavy rain can cause problems in any mountainous area, particularly the Southwest. Large stretches of desert shrub in the west can fuel the spread of [[wildfire]]s. The narrow canyons of many mountain areas in the west and severe thunderstorm activity during the summer lead to [[flash flood]]s as well, which can sometimes be devastating, while [[nor'easter]] snowstorms can bring activity to a halt throughout the Northeast (although heavy snowstorms can occur almost anywhere).
