After a sunny and pleasant late summer weekend, mother nature is dialing up the heat and the air pollution today.

A Code Orange air quality alert is in effect today due to both ground-level ozone and more Canadian wildfire smoke wafting down to the D.C. area. That’s on top of a predicted high temperature of 95.

…AIR QUALITY ALERT IS IN EFFECT FOR MONDAY AUGUST 21 2023…

The Virginia Department of Environmental Quality has issued a Code ORANGE Air Quality Alert Monday for Northern Virginia.

A Code Orange Air Quality Alert means that air pollution concentrations within the region may become unhealthy for sensitive groups. Sensitive groups include children, people suffering from asthma, heart disease or other lung diseases, and the elderly. The effects of air pollution can be minimized by avoiding strenuous activity or exercise outdoors.

For more information on ground-level ozone and fine particles, visit the Virginia DEQ air quality Website at www.deq.virginia.gov.

Despite the current haze, the air quality level in Arlington is listed as moderate (yellow), according to AirNow, but that is expected to deteriorate to Code Orange later in the day.

The air quality in Arlington County has crossed into “Code Red” levels.

The county’s Air Quality Index (AQI), according to the federal government’s AirNow.gov website, was 151 as of 3 p.m., just past the 150 threshold for Code Red. That comes as a new round of Canadian wildfire smoke wafts into the area.

The AQI was in Code Orange levels earlier this afternoon. Code Red levels indicate that “some members of the general public may experience health effects,” while “members of sensitive groups may experience more serious health effects,” according to AirNow.

The smoke is expected to thin locally tomorrow, according to the Capital Weather Gang. But Tuesday is still forecast to be a Code Orange air quality day.

More, below, from a Metropolitan Washington Council of Governments press release.

The Metropolitan Washington Council of Governments (COG) has forecast a Code Orange air day for the metropolitan Washington region tomorrow: Tuesday, July 18. Smoke coming from wildfires in Canada will contribute to the increased levels of fine particle pollution. The Code Orange levels mean the air is unhealthy for sensitive groups, including older adults, children, and people with heart or lung disease.

  • Sensitive groups like people with heart or lung disease like asthma or emphysema, older adults, and children should make outdoor activities shorter and less intense and watch for symptoms such as coughing or shortness of breath.

Residents can check current air quality conditions on COG’s website or the Clean Air Partners website.

On unhealthy air days, COG advises the following actions to improve the air:

  • Avoid lawn mowing or use an electric mower.
  • Use gas or electric grills instead of charcoal.
  • Fill your vehicle’s gas tank after sunset.
  • Take transit, carpool, or work from home.
  • Turn off lights and electronics when not in use and follow tips from your electric utility about how to use less electricity to cool your home.

COG provides air quality forecasts and current air quality conditions for metropolitan Washington. It also educates the public about voluntary actions people can take to reduce pollution and the health risks of bad air quality through its Clean Air Partners program, which is co-sponsored by the Baltimore Metropolitan Council.

It’s been another smoky day in Arlington, and the air quality is still considered “unhealthy” as the workday nears a close.

The Air Quality Index registered at 177 as of 4 p.m. Thursday, solidly in the “Code Red” level.

Tomorrow is expected to also be hazy, but somewhat improved, with a Code Orange alert issued minutes ago.

The concentration of Canadian wildfire smoke in Arlington and the D.C. area is expected to get worse tomorrow.

A Code Red air quality alert has been issued for the region on Thursday. That means that those with certain health issues should avoid outdoor activities and even healthy individuals should limit their time outside.

It comes after a hazy day today, with air quality readings in the lower Code Orange level. The current air quality index reading for Arlington is 137, just below the Code Red threshold of 150, according to AirNow.gov.

With hundreds of wildfires blazing in Canada, particularly Quebec and British Columbia, the area’s air quality will likely continue to fluctuate “over the next several days,” according to Fairfax County, as reported by our sister site FFXnow.

According to the Canadian Interagency Forest Fire Centre, three new fires started today, and there are 476 active blazes, about half of which remain out of control. The agency has recorded 2,988 fires in 2023 so far that have burned through 8 million acres of land.

More on the air quality forecast below, from the Metropolitan Washington Council of Governments.

The Metropolitan Washington Council of Governments (COG) has forecast a Code Red air day for the metropolitan Washington region tomorrow: Thursday, June 29. Code Red levels mean the air is unhealthy for everyone. Smoke coming from wildfires in Canada is contributing to the increased levels of fine particle pollution.

COG advises the following health precautions:

  • Sensitive groups like people with heart or lung disease like asthma or emphysema, older adults, and children should avoid long or intense outdoor activities. Consider rescheduling or moving activities indoors.
  • Healthy individuals should limit long or intense outdoor activities.

Residents can check current air quality conditions on COG’s website or the Clean Air Partners website.

The U.S Environmental Protection Agency also recommends the following during wildfire events:

  • Take it easier during smoky times. If you can see or smell smoke, avoid strenuous activities such as mowing the lawn or going for a run.
  • Reschedule outdoor work tasks and activities to a time when air quality improves. If outdoor tasks and activities cannot be rescheduled and must be conducted when air quality is poor, it is recommended that individuals reduce smoke inhalation by:
    • Limiting the time spent outdoors by only performing essential activities.
    • Taking frequent breaks indoors in places where the air is clean, especially during periods with high outdoor levels of wildfire smoke.
    • If you must work outdoors, choosing a mask that will protect you like an N95 respirator mask. Cloth masks will not protect you from wildfire smoke.
    • Using a portable air cleaner in one or more rooms. If you have a central air system in your home, use it to filter the air.

On unhealthy air days, COG advises the following actions to improve the air:

  • Avoid lawn mowing or use an electric mower.
  • Use gas or electric grills instead of charcoal.
  • Fill your vehicles’ gas tank after sunset.
  • Take transit, carpool, or work from home.
  • Turn off lights and electronics when not in use and follow tips from your electric utility about how to use less electricity to cool your home.

The bulk of today’s storms are moving out — and more Canadian wildfire smoke is about to move in.

The smoke that enveloped Chicago and much of the Midwest today is set to push east toward our region. That has prompted a Code Orange air quality alert for the D.C. area tomorrow (Wednesday).

Code Orange indicates that time spent outdoors could be unhealthy for sensitive groups, but it’s not as bad as earlier this month when the air quality measurement for Arlington hit Code Maroon, the worst and most hazardous level.

More from a Metropolitan Washington Council of Governments press release, below.

The Metropolitan Washington Council of Governments (COG) has forecast a Code Orange air day for the metropolitan Washington region tomorrow: Wednesday, June 28. Smoke coming from wildfires in Canada will contribute to the increased levels of fine particle pollution. The Code Orange levels mean the air is unhealthy for sensitive groups, including older adults, children, and people with heart or lung disease.

On unhealthy air days, COG advises the following health precautions:

  • Children and older adults should reduce outdoor activities.
  • Individuals with respiratory and heart ailments, emphysema, asthma, or chronic bronchitis should limit their activity level. If breathing becomes difficult, move indoors.
  • Healthy individuals should limit strenuous work or exercise, especially outdoors.

The air quality in Arlington has reached the worst level on the scale — “hazardous.”

As of 9 a.m. the federal government website AirNow says Arlington’s AQI, or air quality index, is 313. That puts the county in “Code Maroon” territory, two levels above the more commonly known Code Red.

“Everyone should stay indoors and reduce activity levels,” the website says. Anyone who must be outside today is being encouraged to wear a high quality mask.

Arlington Public Schools, the county parks department and the Arlington Soccer Association — among others — have cancelled all outdoor activities Thursday. Meanwhile, the FAA says that air traffic at D.C. airports may be impacted by the low visibility.

Cameras in Pentagon City show D.C. barely visible through the haze this morning. A rancid campfire-like smell is pervasive throughout the area.

Despite the apocalyptic scene outside this morning, the good news is that some relief is on the way. The National Weather Service says a front is expected to enter the area tomorrow, clearing out some of the smoke.

Tomorrow the air quality for the D.C. region is expected to largely be at “Code Orange” levels, with an average AQI just above 100.

Air quality reading for Arlington as of 9 a.m. Thursday (via airnow.gov)

Update at 10:20 a.m. — The National Weather Service just issued the following Special Weather Statement, suggesting that even thicker smoke may be on the way, before conditions gradually improve.

…POOR AIR QUALITY IN THE MID-ATLANTIC THROUGH FRIDAY DUE TO CANADIAN WILDFIRES…

Due to Canadian wildfires, smoke is prevalent in the Mid-Atlantic region, including the greater Baltimore and Washington metropolitan areas. Under northerly winds, smoke will continue to be pushed south over our area. Thicker smoke will continue to overspread portions of the area, resulting in poor air quality and visibility potentially less than 1 mile. Some improvement is likely through the day, but the smoke likely will continue to affect the area at times until a front on Friday potentially brings some reprieve to fine particle concentrations.

Depending on your location, Air Quality will vary, with much of the area either Code Orange or Code Red through the day today. There is a Code Purple Air Quality Alert for the District of Columbia.

A Code Orange Air Quality Alert means that air pollution concentrations within the region are unhealthy for sensitive groups. Sensitive groups include children, people with heart or lung disease, older adults, pregnant people, and those that spend a lot of time outdoors.

Some areas may see Code Red, which means “unhealthy for the general population.” If you are under a Code Red Air Quality Alert, everyone should keep outdoor activities light and short. For those people in sensitive groups, consider moving all activities indoors.

A Code Purple Air Quality Alert means that everyone may experience more serious heath effects and should avoid outdoor activities, especially individuals with heart and breathing ailments, children, and older adults.

The effects of air pollution on people can be minimized by avoiding strenuous outdoor activity or exercising indoors. Go indoors if you have symptoms.

Update at 11 a.m. — This is now officially the first Code Purple air quality day for fine particle pollution, according to the Metropolitan Washington Council of Governments.

The Metropolitan Washington Council of Governments (COG) has issued a Code Purple Air Quality Health Advisory for the metropolitan Washington region. Current air quality conditions have reached Code Purple, very unhealthy levels for everyone, for fine particle pollution due to ongoing smoke from fires in Canada. The air quality forecast for June 8 has been updated to Code Purple.

COG shares the following health precautions from EPA:

  • Sensitive groups (including children, older adults, and people with heart or lung disease): Avoid all physical activity outdoors. Reschedule to a time when air quality is better or move activities indoors.*
  • Everyone else: Avoid long or intense activities. Consider rescheduling or moving activities indoors.*

The D.C. region has not previously recorded a Code Purple day for fine particle pollution. In 2012, the region recorded two days for ozone pollution that would qualify as Code Purple by the current 2015 standards.

Update at 9:30 a.m. — The air quality has worsened and entered the “Code Maroon” — or “hazardous” — category.

Update at 8:50 a.m. — Air quality in Arlington has reached well into the Code Purple “Very Unhealthy” category, with an AQI of 276. All locals should avoid spending time outside if possible or wear an N95 or similar mask.

Arlington Public Schools and the county parks department, meanwhile, have cancelled all outdoor activities Thursday.

“School will operate as usual today with some modifications,” APS said this morning. “All APS field trips scheduled for today to outdoor locations have been canceled. All APS outdoor activities, including outdoor afterschool activities, have been canceled. APS indoor activities will continue as planned.”

From DPR: ” Due to the air quality, all outdoor DPR and partner programs are canceled for today. We will continue to monitor the health advisory and will notify you of any future related cancellations.”

Earlier: Thursday will be another Code Red air quality alert day for Arlington and the D.C. area.

The good news, though, is that some relief from the wildfire smoke is in sight.

Authorities issued the Code Red alert just before 5 p.m. today, urging people to stay inside and avoid outdoor exercise. From the National Weather Service:

…AIR QUALITY ALERT IS IN EFFECT FOR THURSDAY JUNE 8 2023…
The Virginia Department of Environmental Quality has issued a Code RED Air Quality Alert Thursday for Northern Virginia. A Code Red Air Quality Alert means that air pollution concentrations within the region are unhealthy for the general population. The effects of air pollution can be minimized by avoiding strenuous activity or exercise outdoors. For more information on ground-level ozone and fine particles visit the web site Virginia DEQ air quality web site at www.deq.virginia.gov.

Separately, NWS said in a Special Weather Statement that a front should “bring some reprieve to fine particle concentrations” on Friday.

…POOR AIR QUALITY IN THE MID-ATLANTIC THROUGH FRIDAY DUE TO CANADIAN WILDFIRES…

Due to Canadian wildfires, smoke is prevalent in the mid-Atlantic region, including the greater Baltimore and Washington metropolitan areas. Under northerly winds, smoke will continue to be pushed south over our area. The smoke is expected to be rather thick to start the day Thursday, but may start to decrease through the day. A front on Friday will bring some reprieve to fine particle concentrations.

Depending on your location, Air Quality will vary, with much of the area either Code Orange or Code Red – possibly through Friday. […]

Some areas may see Code Red, which means “unhealthy for the general population.” If you are under a Code Red Air Quality Alert, everyone should keep outdoor activities light and short.

For those people in sensitive groups, consider moving all activities indoors.

The effects of air pollution on people can be minimized by avoiding strenuous outdoor activity or exercise indoors. Go indoors if you have symptoms.

Earlier today, Arlington hit measured air quality levels even worse than the Code Red threshold, though it has since improved somewhat.


(Updated at noon) Air quality measurements have exceeded Code Red levels in the D.C. area, according to the Metropolitan Washington Council of Governments.

It’s no surprise to anyone who can see and smell the smoke outside. The thick haze has been wafting into the region from the north, amid severe wildfires in Canada.

The Council of Government says it expects tomorrow to be a Code Red day as well.

The Metropolitan Washington Council of Governments (COG) has issued a Code Red Air Quality Health Advisory for the metropolitan Washington region. Current air quality conditions have reached Code Red, unhealthy levels for everyone. In addition, tomorrow, June 8, is currently forecast to be a Code Red day.

The region has experienced 6 Code Orange days (unhealthy for sensitive groups) so far this year, and no Code Red days until today.

Smoke coming from fires in Quebec, Canada is contributing to the increased levels of fine particle pollution.

COG advises the following health precautions:

  • Everyone may experience health effects and should limit outdoor activity.
  • Members of sensitive groups like individuals with respiratory and heart ailments, emphysema, asthma, or chronic bronchitis may experience more serious health effects.

Residents can check current air quality conditions and the forecast on COG’s website or by downloading a free air quality app from COG’s Clean Air Partners program.

Among other impacts, at least one Arlington elementary school postponed a planned outdoor field day due to the unhealthy air. And, just before noon, Arlington Dept. of Parks and Recreation cancelled all outdoor programs.

It’s not only people who are being urged to stay inside. The Animal Welfare League of Arlington is reminding residents to keep their pets inside as well.

As of 11 a.m., as pointed out by a reader on social media, the air quality level in Arlington has reached 204 AQI, or the purple “Very Unhealthy” category above Code Red.

“Everyone may experience more serious health effects and should avoid outdoor activities,” the MWCOG air quality table says about the level.

The Arlington County Fire Department, meanwhile, has responded to several calls this morning for people — including an Arlington Public Schools student — experiencing trouble breathing, according to scanner traffic.

Updated at 9:45 a.m. — The Code Orange alert has been changed to a Code Red alert.

Wednesday is forecast to be a “Code Orange” day in Arlington and across the D.C. area.

That’s according to the Metropolitan Washington Council of Governments, which says local air quality will be “unhealthy for sensitive groups.”

Air quality is low across much of the eastern U.S. as smoke from wildfires in Canada is blown south, making for hazy skies and, in some cases, a campfire-like smell outside.

More on the Code Orange alert, below, from MWCOG.

The Metropolitan Washington Council of Governments (COG) has forecast a Code Orange air day for the metropolitan Washington region tomorrow: Wednesday, June 7. Code Orange levels mean the air is unhealthy for sensitive groups. Smoke coming from fires in Canada will contribute to the increased levels of fine particle pollution.

On unhealthy air days, COG advises the following health precautions:

  • Children and older adults should reduce outdoor activities.
  • Healthy individuals should limit strenuous work or exercise, especially outdoors.
  • Individuals with respiratory and heart ailments, emphysema, asthma, or chronic bronchitis should limit their activity level. If breathing becomes difficult, move indoors.
