Experimental Graphical Marine Wind Warnings are a graphical depiction of official marine warnings, based on cumulative wind speed (gridded) forecasts where the resultant warning reflects specific wind speed thresholds. This service will offer shapefiles and static images of graphical marine wind warnings for the next 48 hours, encompassing all of TAFBs tropical oceanic domains (Atlantic Ocean, Caribbean Sea, Gulf of America, and Pacific Ocean). This proposal enables the display of wind-based warnings in the high seas (areas of 34 kt or greater, 48 kt or greater, and 64 kt or greater) for both the 0-24 hour and 24-48 hour forecast periods - a capability beyond the previous wind speed-based warnings. The experimental phase will involve providing this information live, updated four times daily with each forecast cycle. The intent is for these experimental warning graphics to be displayed in a user-friendly format for integration into various navigational ship software and displays, such as Electronic Chart Display and Information Systems (ECDIS). By accessing these products that indicate active Tropical Storm, Hurricane, Gale, or Storm Warnings, captains and mates can make better hazardous weather avoidance decisions for their vessels, crew, and cargo. The Experimental Graphical Marine Wind Warning will be available at the following link: https://www.nhc.noaa.gov/gis/marine/warnings/ A description of the Experimental Graphical Marine Wind Warnings can be found at the following link: https://nsdesk.servicenowservices.com/api/g_noa/nwspc/res2/6183e 9e61b283a540d690f67624bcbab Input on the Experimental Graphical Marine Wind Warnings is being sought from users. https://www.surveymonkey.com/r/ExpGraphicalMarineWindWarnings_20 25 Additional Comments may be sent to: Christopher W.
