Wildfires burning across Canada, the United States, and Mexico are frequently observed to send smoke throughout the entire continent.
This widespread phenomenon means that the current status of air quality across both the United States and Canada can be significantly affected by distant blazes. Notably, much of the smoke that has recently impacted the Midwest and Northeastern United States has been traced back to fires burning across the border in Canada.
Tracking Continental Smoke Patterns
Smoke and particulate matter generated by these fires possess the capability to travel considerable distances from their initial origin points. This allows for far-reaching impacts on air quality for regions well removed from the actual fire locations.
The status of air quality across the United States and Canada is continuously monitored. Data highlights the most affected cities currently being tracked as these plumes move across the landscape. The National Oceanic and Atmospheric Administration’s HRRR-Smoke model provides hourly near-surface wildfire smoke concentrations, offering detailed insights into the spread of these atmospheric conditions.
Understanding Smoke Forecasts
Forecasting the movement of wildfire smoke is an integral part of understanding future air quality conditions. These forecast smoke maps are based on various models, though they may occasionally underestimate the true extent of smoke. This underestimation can occur due to factors such as cloud cover or other atmospheric obstructions that obscure the full picture.
Contours on these maps show estimates of wildfire smoke near the surface, providing a visual representation of where concentrations are expected to be highest. These models are crucial for understanding the potential impact on air quality in affected regions, including the Northeastern United States.
