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