Forest Fires All Over North America

This has been a remarkably heavy year for forest fires and it's still very early in the season. The last few summers the West Coast has experienced many days of terrible air quality. This year the East Coast is experiencing it. Last week cities like New York, Philadelphia and Toronto has some of the poorest air quality in the world and residents were advised to stay indoors. Here is a map from NASA showing where major fires are burning. The red dots show smaller fires.

A map from Scientific American shows how the smoke has moved from eastern Canada to New York City (the only city, apparently).

Here's one more map from the Fire, Weather and Avalanche Center showing active fires in the United States. It gives more details but doesn't cover Canada, where the largest fires are. The purple dots are lightning strikes.
