Smoke from deadly wildfires burning in California reached New Jersey on Monday.

A light haze was visible in areas from Philadelphia to New York City. Gary Szatkowski, former head of the National Weather Service Mount Holly office, tweeted a map showing the smoke spreading to the east coast.

So if you thought it was just a bit hazy this afternoon, we have a California fire smoke plume moving through. pic.twitter.com/PsYNlAWrgA — Gary Szatkowski (@GarySzatkowski) November 19, 2018

In parts of South Jersey and the Philadelphia-area, the air quality was reported as "moderate," according to AirNow, a federal government-run website that reports air conditions.

"Unusually sensitive people should consider reducing prolonged or heavy exertion," the site's report said.

Wow. I knew tonight’s sunset over New York City seemed different, and I should’ve realized! Wildfire smoke is in the air, all the way from California.

A similar haze from the devastating fires was reported across the country from Texas to Utah. There were no warnings of any serious health concerns from the smoky conditions outside of California.

The Camp Fire, raging in Northern California's Butte County, has burned 151,000 acres and killed at least 77 people, according to state officials. In Southern California, the Woolsey Fire killed three people and burned 96,949 acres.
