MIAMI – A tropical weather product originally unveiled to the public in 2017 is receiving a major upgrade in 2025 that the National Hurricane Center believes will help communities prepare for impacts.
According to the agency, its meteorologists will now have the ability to issue forecasts for potential tropical cyclones up to 72 hours before impacts begin – an increase of 24 hours compared to the previous usage of the product.
The potential tropical cyclone designation allows the NHC and other governments to issue tropical weather watches and warnings when a disturbance isn’t quite at the strength of a tropical storm or hurricane but could reach that status within 36 hours.
Dr. Michael Brennan, director of the NHC, spoke with FOX Weather about the changes and said the advancements will help communities in the direct path of a cyclone.
"Back in 2017, we implemented what we call these potential tropical cyclone advisories that let us get watches and warnings out as much as 48 hours in advance of the onset of impacts and land areas for systems that weren’t yet even a depression or storm" said Brennan. "It’s been really successful, and we used it a lot. The best example from last year is Helene that formed down in the Caribbean and then made landfall in Florida as a Category 4 hurricane just a few days later."
