Global tropical storm track and intensity data in JSON format.

Item	Value
Format	JSON
Region	Global
Forecast Base Time	02:00, 08:00, 14:00, 20:00 UTC
Forecast Duration	Based on storm lifetime
Average Size	~44 KB

Notes

• When no tropical storms are active, tropCount is "0" and tropInfo is an empty array.
  This is a normal response — it simply means no storms exist at the requested time.
• tropCount reflects the number of active storms in the dataset, not a forecast count.
• analysisInfo contains the current position; forecastInfo contains predicted positions;
  trackInfo contains the historical track.
• Coordinates (lat, lon) are in arc-minutes. Divide by 60 to convert to decimal degrees.
