NJ Air Quality Index To Hit Triple Digits Tuesday: See Forecast

NEW JERSEY - Hazy conditions from the Canadian wildfires are in the forecast, with over a dozen New Jersey counties under an air quality alert as AQIs are expected to reach triple digits by Tuesday afternoon, forecasters said.

The New Jersey Department of Environmental Protection issued a code orange air quality alert through Tuesday night. Air quality within the region “may approach or exceed unhealthy standards," officials said.

The Code Orange will be in place for 16 counties: Sussex, Warren, Morris, Hunterdon, Somerset, Middlesex, Monmouth, Mercer, Salem, Gloucester, Camden, Burlington, Ocean, Cumberland, Atlantic and Cape May.

As of Tuesday at noon, the air quality across the Garden State was largely “moderate” at around 52 to 107 AQI, according to AirNow.gov, save for the Southern Bay, Southern Coastal and Delaware Water Gap regions, which are currently at “good” AQI levels. Tuesday is forecast to see AQIs between 90 and 100 later in the day, the federal website said.

Risky AQI, which may pose a hazard for groups who are sensitive to air pollution, begins at values above 50, according to the federal website.

“Sensitive groups" includes children and teenagers, older adults, people with asthma, and those with heart or lung conditions. It also includes people who spend time outside working or doing rigorous physical exercise.

Last month, the air quality in the Garden State rose to dangerously unhealthy levels as the skies turned orange due to the wildfire haze. The unhealthy air quality closed schools and government offices for at least a day on June 7.

Relief from the smoke crossing the Canadian-U.S. border won’t be immediate, experts said. Large fires in Alberta, British Columbia and Saskatchewan are likely to keep churning out smoke throughout the summer and possibly into early fall, said Montana Department of Environmental Quality meteorologist Aaron Ofseyer.

“The worst is over with this round,” Ofseyer said. “Unfortunately there’s still a ton of wildfire smoke north of the border. Anytime we get a North wind we’re going to be dealing with Canadian wildfire smoke.”

AccuWeather-owned Plume Labs says the air quality in the region is “poor” as the “air has reached a high level of pollution” that is “higher than the maximum limit for 24 hours established by WHO.” The website predicts AQIs to improve through Tuesday evening before reaching triple-digit highs again on Wednesday.

Aside from bad air, the region is also slated for wet weather Tuesday afternoon. Hot and humid temperatures in the high 80s and low 90s will pave the way for scattered afternoon storms, the National Weather Service said, with the highest chances of storms near and northwest the I-95 corridor. Additional storms are expected Wednesday and Thursday before cooler, drier weather sets in this weekend.
