Consider elevating electrical components and major HVAC components at least 1 foot above the base flood elevation - and higher for additional peace of mind. Prevent or reduce flood damage by floodproofing your home. For more information, ask your insurance agent. Keep all records in waterproof containers and take them with you when you evacuate. Then create files that include serial numbers and store receipts for electronics and appliances. Videotape or photograph all major household items and valuables.

Storm surge warning: Danger of life-threatening storm surge flooding within 36 hours. Storm surge watch: Possible life-threatening storm surge flooding within 48 hours. The National Hurricane Center will issue potential storm surge maps that show the height above ground that the water may reach, which will be available from the National Weather Service. Storm surge can and has affected both mainland Hyde County and Ocracoke Island, such as during Hurricane Irene in 2011. New for 2016, the National Weather Service may issue storm surge watches and warnings in advance of an approaching tropical storm or hurricane when life-threatening storm surge may push water up on to land. They develop more gradually than flash floods, but still are a threat to life and property.Īreal flood advisory: Minor general or areal flooding is occurring, imminent or highly likely.Īreal flood warning: General or areal flooding is occurring, imminent or highly likely.Ĭoastal floods occur when seawater is contributing to flooding, including from overtopping or breaching barriers during tropical systems, nor’easters, storms or wind tides.Ĭoastal flood watch: Coastal flooding conditions are possible.Ĭoastal flood warning: Coastal flooding is occurring, imminent or highly likely. River Flood Warning: River flooding is occurring or imminent at one or more forecast points along a river.Īreal floods are general floods over large areas of streets, low-lying areas, storm drains, creeks and small streams. River Flood Watch: River flooding is possible at one or more forecast points along a river. It can be produced when heavy rain accumulates quickly, including from slow-moving or multiple thunderstorms occurring over the same area, as well as from dam breaks, levee failures or heavy rain.įlash flood watch: Conditions leading to flash flooding are possible within the next six to 36 hours.įlash flood warning: Flash flooding is occurring, imminent or highly likely within the next two hours.

In fact, almost 25 percent of flood insurance claims come from low-to-moderate-risk areas mapped outside the 100-year floodplain, but the chances of flooding outside the mapped areas are less than 1 percent each year. However, floods can happen anywhere, even if those areas are not shaded on the maps. In designated 100-year floodplains, the map also will show the base flood elevation (BFE), or the approximate depth of that 1 percent chance flood. The 100-year floodplain is the area where there is a 1 percent chance of flooding in any given year, and the 500-year floodplain is the area where there is a 0.2 percent chance of flooding in any one year. Enter your address to view your flood risk. These maps show the FEMA 100-year and 500-year flood plains for your property. You also should know the general flood risk of your property, which can be viewed using the FEMA National Flood Insurance Rate Maps (FIRMS) through the Flood Rate Information System.
