Wildfire Smoke Affects 100 Million Americans

Why it matters locally: While the current wildfire smoke affecting 100 million Americans is primarily from Canadian fires impacting the East Coast, Washington state is highly susceptible to wildfire smoke, particularly from blazes in British Columbia and within its own borders, which can severely impact air quality and public health.

Smoke from Canadian wildfires now impacts approximately 100 million Americans. This smoke has expanded its reach, affecting additional cities across the United States. Tom Costello, an NBC News correspondent, provided the latest information regarding the smoke's movement and its impact on these new U.S. locations.
