The National Weather Service, in cooperation with the Arkansas Division of Emergency Management, has proclaimed the week of March 6th through 10th as Flood Safety Awareness Week in Arkansas. Each day during the week will feature information about a different flood related topic. ....Flood Hazards... A flood is defined as any high flow, overflow, or inundation of water that causes or threatens damage. Flooding can occur with prolonged rainfall over several days, intense rainfall over a short period of time, or when water from an existing source moves too quickly. Brief descriptions of the various types of flooding you may experience are found below. Flash Flooding: Flash flooding is a rapid and extreme flow of high water into a normally dry area, or a rapid water level rise in a stream or creek above a predetermined flood level beginning within six hours of the causative event (such as intense rainfall, dam failure, or ice jam). River Flooding: River flooding occurs when rivers rise and overflow their banks, inundating areas that are normally dry. Tropical Systems: At any time of the year, a storm from over the ocean can bring heavy precipitation to the coast and move inland across the midsouth. Whether such a storm is tropical or not, prolonged periods of heavy precipitation can cause freshwater flooding as the storm system moves inland. Burn Scars/Debris Flows: Wildfires burn away the vegetation of an area, leaving behind bare ground that tends to repel water. When rain falls, it runs off a burn scar towards a low lying area sometimes carrying branches, soil, and other debris along with it. Without vegetation to hold the soil in place, flooding can produce mud and debris flows. Snowmelt: Flooding due to snowmelt most often occurs in the spring when warming temperatures quickly melt the snow. The water runs off the still partially frozen or already saturated ground into nearby streams and rivers, causing them to rapidly rise and sometimes overflow their banks. Dam Break and Levee Failure: A break or failure can occur with little to no warning. Most often they are caused by water overtopping the structure, excessive seepage through the surrounding ground, or a structural failure. && Understanding the different flood hazards and knowing the actions to take before, during, and afterwards can help you protect your life, the lives of your loved ones, and the your property.
