FEMA's Hurricane Incident Journal provides relevant spatial decision-making support for FEMA leadership and a view into federal information available to the general public. This website is a part of the FEMA GeoPlatform.   Individual applications shown in this journal are linked to at the bottom of each section. Modeled damage assessments are based on flood depth grids, then verified with satellite imagery. Depth grids can be Observed (data from river, coastal, tide gauges), or Forecasted (created from Advanced Hydrologic Prediction Service, AHPS, forecasts). Remote Sensing contains flood extents and other data from NASA and Copernicus. Surge Inundation Dashboard Analysis will update when there is greater than 10% chance of 5' or more of Surge Inundation.   Hurricane Force Winds Dashboard  Analysis will update automatically when there is a greater than 50% chance of hurricane force winds (64 knot, 74 mph) over land. Wind data is taken from the latest NOAA advisory.
