The latest High-Resolution Ensemble Forecast (HREF) probabilities indicate a significant likelihood of strong winds impacting the East Tennessee mountains and foothills. Data suggests an 80% to 100% chance of wind gusts reaching or exceeding 40 mph, meeting Wind Advisory criteria. Portions of the foothills that are particularly prone to mountain wave winds, such as Camp Creek, are also included in this high-probability zone.
Meanwhile, the Cumberland Plateau faces a 50% to 80% probability of experiencing gusts over 40 mph. However, the likelihood of winds reaching High Wind Warning criteria (gusts of 57 mph or higher) in the East Tennessee mountains remains low, with current HREF probabilities ranging from 20% to 40%.
Given this data, the National Weather Service has issued a Wind Advisory for the East Tennessee mountains and foothills. The Cumberland Plateau is currently excluded from this advisory, but forecasters will continue to monitor updated high-resolution models and may include it in future forecasts if conditions warrant.
