The National Weather Service is developing a new web page for the Atlantic hurricane basin which will interactively display and communicate local tropical storm and hurricane decision-making information based upon on local forecast databases, local statements, and hurricane threats and impact grids.

Users are reminded that tropical cyclone threat grids (wind, flooding rain, storm surge, and tornadoes) became operational on June 1, 2015 in the National Digital Forecast Database (NDFD). The grids are available at: https://digital.weather.gov/. Further information on these grids can be found at: http://www.nws.noaa.gov/om/notification/tin15-16tc_threat_grids.htm.
