This service contains the tropical cyclone data for possible storms. Specific storms can be identified on this summary service by the storms wallet. Wallet information is found in the "idp_source" attribute field of the data as the leading three characters.

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

7 Day Probability Outlook Area and 7 Day Probability Outlook depict the significant area of disturbed weather as a polygon and point respectively out to 168 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).

Arrival Time of TS Winds depicts the earliest reasonable or the most likely arrival time of tropical storm force winds.

Inundation depicts the total water level that occurs on normally dry ground as a result of the storm tide.

Tidal Mask depicts the total water level that occurs on normally dry ground as a result of the storm tide, plus intertidal zones/estuarine wetlands.

Probabilistic Winds depict the probability of 34, 50 and 64 knot winds.
