This map describes the current & recent location of tropical storms, as well as forecast positions and probable track of tropical storms. The areas currently covered by the live feeds are the Atlantic and Eastern Pacific, the Central Pacific (Hawaii, etc.), and the Western Pacific and Indian Ocean. The data sources are the National Hurricane Center, Central Pacific Hurricane Center and Joint Typhoon Warning Center. The shaded area around the forecast track is called the "cone of uncertainty." The cone represents the probable track of the center of a tropical cyclone. More info. About the data: Weather Stations (NOAA METAR): Typical METAR contains data for the temperature, dew point, wind speed and direction, precipitation, cloud cover and heights, visibility, and barometric pressure. A METAR may also contain information on precipitation amounts, lightning, and other information. Active/Recent Hurricanes: The active data describes the path and forecast path of tropical activity including points, tracks, watch/warnings, and the cone of uncertainty. More info. Past Positions and Observed Track are products of the National Hurricane Center (NHC).Storm Surge: The SLOSH (Sea, Lake, and Overland Surges from Hurricanes) model is a numerical model used by NWS to compute storm surge. Storm surge is defined as the abnormal rise of water generated by a storm, over and above the predicted astronomical tides. Flooding from storm surge depends on many factors, such as the track, intensity, size, and forward speed of the hurricane and the characteristics of the coastline where it comes ashore or passes nearby.To visualize Storm Surge Data across 5 Storm Categories, see this map http://noaa.maps.arcgis.com/apps/StorytellingTextLegend/index.html?appid=b1a20ab5eec149058bafc059635a82ee
