Delaware is also in a Code Red for potential impacts of the smoke.
More smoke from the wildfires will be visible in our region today, particularly at points south of Philadelphia. The impacts will be far less than the air quality issues we saw earlier this month in the Philadelphia region.
Still, in places where the air quality is considered "unhealthy for sensitive groups," the elderly, children and people with respiratory issues such as asthma should remain inside as much as possible. The general public should be OK.

In places where the air quality is considered "unhealthy," the general public will experience health effects.
Wednesday night, health officials advise the public to put off outdoor activities, like mowing the lawn or filling up their gas tank.
If this smoke settles in overnight, Thursday morning around 7 a.m. could be the worst time for air quality.
This is all happening as Canada is on track for its worst wildfire season in nearly 30 years, with maps showing more than 250 "out of control" blazes burning across the country. Our region has faced the most impacts from fires burning in the provinces of Quebec and Ontario - the smoke has carried on the wind and traveled hundreds of miles before coming down to surface level.
Nearly 3,000 fires since the beginning of 2023 have burned more than 19 million acres of forest in Canada.
Early Thursday, you can see the thickest smoke swirling away from our region and out to sea.
