“It was Only an EF-2 Tornado”: Rethinking Weather Safety Messaging in Middle Tennessee

Several new residential areas have rapidly emerged across Middle Tennessee in recent years due to a significant population surge. With urban sprawl progressing at nearly 100 people per day, ongoing construction has become the norm in Nashville, Tennessee and its environs. Amid this rush to build housing, many developments have opted to adhere only to minimum county or state building codes, which stipulate homes must withstand winds up to 90 mph. However, Middle Tennessee lies in "Dixie Alley," notorious for a relatively high frequency of nighttime tornadoes, presenting a huge challenge for effective dissemination and reception of tornado safety messages.

Also, in this region, tornado events in 2018, 2020, and 2023 have challenged the notion of safety in presumably well-constructed homes. During these events, numerous single and two-story houses have been completely destroyed, while neighboring homes suffered typical EF-2 damage. Despite residents following standard safety protocols, their homes succumbed to EF-2 winds, prompting questions within the National Weather Service (NWS) and the emergency management community about the adequacy of current tornado safety messaging.

This presentation will stress the collaboration within the weather and emergency management community is essential for reassessing whether conventional tornado safety guidelines remain appropriate for EF-2 tornadoes in Middle Tennessee while facing the communication challenge of nocturnal tornadoes.
