Thu Oct 31 07:20:00 UTC 2024: ## National Weather Service Changes Winter Alert System in East Tennessee
**KNOXVILLE, Tenn. (WVLT)** – The National Weather Service (NWS) is implementing changes to its winter weather alert system in East Tennessee, affecting frost/freeze alerts and wind chill advisories.
Effective immediately, frost/freeze alerts and warnings will only be issued between May 1 and September 30, reflecting the growing season in Tennessee. This change is designed to highlight the occurrence of colder weather outside of the typical growing period. However, southeast Kentucky will continue to receive frost/freeze alerts year-round as the state has not yet adopted the new method.
Meanwhile, wind chill advisories and warnings are being replaced with extreme cold watches and warnings. This change combines frigid temperatures with wind chill factors, focusing on the potential danger posed by cold weather.
Extreme cold advisories will be issued when temperatures reach near 5 degrees Fahrenheit, while extreme cold watches and warnings will be issued for temperatures at or below 5 degrees below zero.
“Extreme cold warnings are issued when life is in danger, especially with temperatures reaching zero degrees or lower,” said Anthony Cavallucci, warning coordination meteorologist with the NWS Morristown.
The NWS stresses that winter weather warnings generally develop slowly, allowing for preparation. However, the agency urges residents to take winter storm watches seriously and prepare accordingly before a warning is issued.
Criteria for winter storm watches and warnings remain unchanged, but residents in East Tennessee are encouraged to stay informed as the cold season approaches. The WVLT First Alert Weather App provides updates on colder temperatures and weather alerts.
