Changes Coming to National Hurricane Center Products

Posted by on Thursday, March 16, 2017

There will be several changes coming to the U.S. National Hurricane Center this year.

Beginning with the 2017 hurricane season, the National Weather Service (NWS) will issue storm surge watches and warnings to 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, subtropical cyclone, post-tropical cyclone, or (pending final NWS approval) a potential tropical cyclone.

NHC will have the option to issue advisories, watches, and warnings for disturbances that are not yet a tropical cyclone, but which pose the threat of bringing tropical storm or hurricane conditions to land areas within 48 hours. Under previous longstanding NWS policy, it has not been permitted to issue a hurricane or tropical storm watch or warning until after a tropical cyclone had formed.

NHC will begin issuing experimental Time of Arrival of Tropical-Storm-Force Winds graphics.

The NHC has updated the look of its tropical cyclone advisory graphics. The suite now has a consistent look across the various graphics, with cleaner fonts and softer colors.

Annual update to the track forecast error cone.
