This service contains the tropical cyclone data for the five possible storms in the Atlantic/Caribbean basin, The layer names are prefixed with the storm (AT1,AT2....) and are in bold
2 Day Probability Outlook Area and 2 Day Probability Outlook depict the significant area of disturbed weather as a polygon and point respectively out to 48 hours
5 Day Probability Outlook Area and 5 Day Probability Outlook depict the significant area of disturbed weather as a polygon and point respectively out to 120 hours.
Forecast Points depict the and current position and forecast positions of the storm out to 120 hours.
Forecast Track is a line connecting the forecast points.
Forecast Cone depicts the forecast "Cone of uncertainty".
Watch-Warning depicts a "watch/warning" line indicating which sections of the coastline are in a watch/warning state due to the storm.
Past Points depicts the "best" track of the storm to the current time.
Past Track is a line connecting the past points.
Best Wind Radii shows how the size of the storm has changed and the areas potentially affected so far by sustained winds.
Surface Wind Field is intended to show the areas potentially being affected by sustained winds of tropical storm force (34 knot), (50 knot) and hurricane force (64 knot).
Forecast Wind Radii are intended to show the expected size of the storm and the areas potentially affected by sustained winds of tropical storm force (34 Knot), (50 knot) and hurricane force (64 knot).
Probabilistic Storm Surge depict the probability, in percent, of a specified storm surge occurring during the forecast period.
Probabilistic Winds depict the probability of 34, 50 and 64 knot winds.
