A powerful new tool for flood response and mitigation are digital geospatial flood-inundation maps that show flood water extent and depth on the land surface. The map-based user interface can be used to delineate drainage areas, get basin characteristics and estimates of flow statistics, and more. Waterways=dark blue. Tropical Storm Eta is tracking near South Florida, where heavy rainfall, strong winds, storm surge and high surf are expected to continue on Monday. The Snoqualmie Valley is prone to flooding when heavy rain or snow melt occurs. FEMA is the official public source for flood maps for insurance purposes: NOAA is responsible for producing flood forecast maps that combine precipitation data with USGS streamflow data: Accurate estimates of flood frequency and magnitude are a key component of any effective nationwide flood risk management and flood damage abatement program. A flash flood occurs when runoff from excessive rainfall causes a rapid rise in the water height (stage) of a stream or normally-dry channel. Even after floodwaters recede, roads and bridges may be weakened and could collapse.
