The ability to issue separate warnings for these two hazards will save lives by better identifying the specific tropical cyclone hazards communities face. Operational storm surge watches and warnings will highlight areas along the Gulf and Atlantic coasts of the continental United States that have a significant risk of life-threatening inundation from a tropical cyclone, a subtropical cyclone, or a post-tropical cyclone.
In addition, the NWS plans to issue tropical cyclone watches and warnings for tropical disturbances that have not yet become a tropical cyclone, but pose a threat of bringing tropical storm or hurricane conditions or life-threatening tropical cyclone storm surge inundation to land areas within 48 hours. These changes will affect the way broadcasters communicate and display official tropical cyclone watches and warnings from the NWS. This presentation will outline these products and services in greater detail and provide broadcasters with information they can use to incorporate these changes into their messaging and operations.
