Storm graphics show forecasted data points that aren't included in the API response

I pulled a 'currenthurricane' report just now, and inside the JSON response I see information about Invest 93L. The 'forecast' and 'ExtendedForecast' attributes are just empty arrays. However, when I look at the WU Tropical Weather web page, you have graphics showing a number of forecasted points. (I'll add them to this post.)

I'm wondering, where do these forecasted data points shown on the graphics come from? Why do they sometimes exist in the JSON 'forecast' and 'ExtendedForecast' arrays, and sometimes not? Please explain the differences between the JSON responses and the graphics on the WU site. Is there any way for API users to get the data points on these graphics when they do not appear in the 'forecast' or 'ExtendedForecast' sections of the JSON response? Thanks!

Those are model tracks, not official forecasts.  Those are not included in the API

Thanks for the reply.

What are the model tracks based on? Do they come from the National Hurricane Center, or are they something put together by Weather Underground?
