The Hurricane Network issues advisory packages every six hours when there is a tropical cyclone inside Northern Atlantic, Eastern Pacific, and Central Pacific areas of responsibilities. These advisories include Public Advisory and Forecast Discussion products for each cyclone in six hourly intervals (0300 UTC, 0900 UTC, 1500 UTC, and 2100 UTC). When there are active watches or warnings for any coastal areas, intermediate public advisories are issued every 2 hours in between the complete advisory packages (0600 UTC, 1200 UTC, 1800 UTC, and 0000 UTC).
When there is a significant change in the storm intensity or track, The Hurricane Network may opt to issue a special advisory package, which can be issued whenever that package is needed.
When there is a need to update on a significant cyclone making landfall along the United States coastline, change in watches and warnings, or minimal change in intensity, The Hurricane Network could issue a Tropical Cyclone Update product, which can be issued whenever needed.
Official government advisories on active tropical cyclones can be found on the National Hurricane Center website.
