Alerts in force

An Air Quality Alert is issued by the National Weather Service on behalf of a state or local agency when pollution is expected to reach a level that harms health. An Air Stagnation Advisory means the air will not move enough to clear what is already in it.

None are in force near Desert Shores right now. All California warnings.

The forecaster’s discussion

Written by Imperial County Air Pollution Control District for Niland and filed with AirNow.

Today, light winds through much of the day will lead to pollutant build-up in the Imperial Valley. In addition, sunshine and warm temperatures will support ozone formation. Furthermore, as an upper-level trough of low pressure approaches the region, gusty west-northwesterly winds will develop in the afternoon and evening, generating blowing dust. These conditions will lead to Moderate AQI levels. Tomorrow, a weak upper-level low will remain over the Imperial Valley, aiding atmospheric mixing. However, light and variable surface winds will reduce pollutant dispersion. Additionally, mostly sunny skies and temperatures in the upper-90s will enhance ozone production. As a result, AQI levels will be mid-Moderate.

Fine particles in micrograms per cubic meter, ozone in parts per billion as an 8-hour average. The index for each hour is EPA’s: the ozone figure is already the 8-hour average the ozone index is defined on, and the particle figure is run through EPA’s NowCast, which is how an hourly PM2.5 concentration becomes an index.

Smoke

NOAA’s analysts have not drawn smoke over Desert Shores in satellite imagery today.

NOAA’s model forecasts near-surface smoke peaking at 1.5 µg/m³ around Tue, 2:00 AM PDT.

What this means

Moderate

Air quality is acceptable. There may be a risk for some people, particularly those who are unusually sensitive to air pollution.

Who is affected
People who are unusually sensitive to ozone or fine particles.
What to do
If you are unusually sensitive, consider making long or intense outdoor activity shorter or easier.
Index range
51 to 100

Category descriptions are the Environmental Protection Agency’s own.

What these numbers are. An index beside a monitor’s name is a measurement, published hourly by AirNow and preliminary until the operating agency certifies it. A category for today or tomorrow is a state or local agency forecaster’s own forecast for a reporting area. An hourly index is NOAA’s air quality model on a five-kilometer grid, not a reading from any instrument. Where a town has no monitor within reach, only the model figures appear, and the page says so.
