Air Quality Alert


NMZ208-212>218-220-224-241-221900-

Air Quality Alert Message
Relayed by National Weather Service Albuquerque NM
302 PM MDT Sat May 21 2022

...AIR QUALITY ALERT...

The following message is transmitted at the request of the New Mexico
Departments of Health and Environment, United States Forest Service
and the Interagency Wildland Fire Air Quality Response Program.

* WHAT...A shallow dome of unseasonably cool air along and east of the
  central mountain chain this afternoon will be reinforced by early
  evening with the leading edge of this cooler air advancing much
  farther west and south than this past nightpossibly as far west
  as the Continental Divide by Sunday morning. Smoke from the highest
  elevations of Hermits Peak-Calf Canyon fire will initially be
  transported to the east-northeast while very little eastward smoke
  transport is expected at the lower elevations. However, beginning
  late today or early evening, any smoke along the east slopes of the
  Sangre de Cristos will be pushed back toward the west and
  northwest. There is the potential for smoke impacts to increase and
  expand along the Rio Grande Valley west of the Sangre de Cristos, as
  well as areas south and southwest of the Hermits Peak Calf Canyon
  fire perimeter to include Pecos Canyon, Glorieta and Santa Fe during
  the evening and overnight. Meanwhile, across the Gila National
  Forest and surrounding areas, significantly drier west- southwest
  transport winds will prevail through the evening with smoke
  transport toward the east-northeast. Thereafter, smoke from the
  Black and Bear Trap fires will tend to push more toward the north-
  northwest then back to the northeast going into Sunday. Smoke from
  other wildfires and localized blowing dust will contribute to
  increasingly hazy skies especially for the middle Rio Grande Valley
  corridor.

* WHERE...Locations most likely to experience the most significant
  impacts from smoke include the following counties: Catron, western
  Colfax, northwest Lincoln, western Mora, southeastern Rio Arriba,
  eastern Sandoval, western San Miguel, northern Santa Fe, Socorro,
  Taos, southwest Torrance. More details on impacted locationsand
  latest air quality information can be found athttps://fire.airnow.gov

* WHEN...Remainder of this afternoon through at least 1pm MDT Sunday,
  May 22

* IMPACTS...Those with conditions such as asthma, chronic obstructive
  pulmonary disease, interstitial lung disease, lung cancer, and heart
  disease will be especially vulnerable to impacts from poor air
  quality, as will adults over age 65, young children, and pregnant
  women if smoke concentrations become unhealthy.

* HEALTH INFORMATION...Remember, your eyes are your best tools to
determine if it is safe to be outside. Use the 5-3-1 Method available
at https://nmtracking.org/environment/air/FireAndSmoke.html.

If visibility is:

Under 5 miles, the air quality is unhealthy for young children,
adults over age 65, pregnant women, and people with heart
and/or lung disease, asthma or other respiratory illness.
Outdoor activity should be minimized.

Around 3 miles, young children, adults over age 65, pregnant
women, and people with heart and/or lung disease, asthma or other
respiratory illness should avoid all outdoor activities.

Around 1 mile, the air quality is unhealthy for everyone. People
should remain indoors and avoid all outdoor activities including
running errands. Unless an evacuation has been issued, stay inside
your home, indoor workplace, or in a safe shelter.

With the ongoing COVID-19 pandemic affecting New Mexico and with the
wildfire season underway, New Mexicans will need to take extra
precautions. Smoke from wildfires may cause people to have more
severe reactions if they are infected COVID-19. The best way to
protect against the potentially harmful effects of wildfire smoke and
to reduce the spread of COVID-19 is to stay home and create a clean
indoor air space. NMDOH offers tips here:

https://nmtracking.org/environment/air/IndoorQuality.html and
https://cv.nmhealth.org

New Mexicans will also need to take steps to keep their homes cool to
avoid heat-related illnesses. NMDOH offers tips here:

This hazardous weather outlook is for portions of central...east
central...south central and southeast Colorado.

.DAY ONE...This Afternoon and Tonight

Snowfall will continue over the southeast mountains and parts of
the eastern plains through this afternoon. Localized convective
snow bands could cause higher snow accumulations through today
over Fremont and Huerfano Counties in addition to the mountains.

Over the lower-lying areas, additional of two inches are expected
this afternoon. Under areas impacted by the snow bands, up to six
additional inches will be possible. The mountains will be seeing
an additional 3 to 6 inches by the end of the day today.

Tonight, after a lull this evening, snowfall will redevelop over the
mountains overnight, with snow showers possible at lower elevations.
Overnight accumulations will be light, generally an inch or two in
the mountains, and an inch or less across most valleys and the I-25
corridor.


.DAYS TWO THROUGH SEVEN...Sunday through Friday

An unseasonably cool and unsettled weather pattern remains in the
offing through early next week, as a broad upper trough is
expected to slowly move across the Rockies. This will keep daily
chances of showers and possible thunderstorms across south central
and southeast Colorado into the middle of next week, with the
best chances of widespread precipitation coming Monday and Tuesday.
Temperature profiles also support the potential for accumulating
snowfall across the higher terrain, generally at or above 9000
feet, through Tuesday.

Drier and much warmer conditions are expected to return for the
later half of next week.

.SPOTTER INFORMATION STATEMENT...

Weather conditions that meet reporting criteria for spotters will
be likely over portions of the region.
