Burlington, Vermont – Vermonters woke up to thick fog Monday morning, especially in river valleys and across bridges, with visibility near zero in some spots. As the fog burns off under late July sun, wildfire smoke will cycle back into the region this afternoon, creating hazy skies and reducing air quality.
According to the National Weather Service in Burlington, the smoke will settle across much of northern and central Vermont after 10 a.m., compounding the heat expected to peak in the mid to upper 80s. The combination of stagnant air and rising temperatures increases the risk of heat-related illness, particularly for vulnerable populations and outdoor workers.
Drivers should allow extra time for the commute, particularly along I-89, U.S. Route 7, and in valleys such as Winooski and Lamoille. Use low-beam headlights in fog and avoid high beams, which can worsen glare. Residents are urged to hydrate, wear lightweight clothing, and stay in air-conditioned environments when possible. Those with respiratory issues should monitor conditions and limit outdoor exposure.
Smoke and haze are expected to linger through sunset, with a weak front offering some clearing by Tuesday. Additional air quality alerts could be issued if smoke concentrations increase.
