Monday is an Ozone Code Orange Air Quality Action Day for Delaware

Today is an Ozone Code Orange Air Quality Action Day for Delaware – particularly the northern parts of the state.

Mostly sunny skies and temperatures in the upper-80s will enhance ozone formation. Furthermore, calm to light and variable winds will hinder dispersion and allow pollutants and ozone precursors to accumulate, primarily in the northern portion of the state. As a result, AQI levels are anticipated to be Unhealthy for Sensitive Groups for ozone and low-Moderate for Particulate Matter 2.5.

Tuesday, August 5: Easterly to east-southeasterly winds during the afternoon will recirculate thin-density wildfire smoke into the state. Additionally, periods of sunshine and temperatures in the upper-80s will continue to promote ozone development. Therefore, AQI levels are anticipated to be high-Moderate for ozone and low-Moderate for PM2.5.

Local conditions may vary; therefore, we recommend checking Delaware’s air data at https://www.airnow.gov/  or de.gov/airdata for current air monitoring data.

A Code Orange air quality forecast for ozone is a level of pollution that can be unhealthy for sensitive groups, such as young children, the elderly, and those with heart and/or respiratory conditions. Such persons should limit outdoor activities, especially those that require a high level of exertion. Any health-related questions should be directed to the Division of Public Health at 302-744-4700. All other questions should be directed to the Division of Air Quality at 302-739-9402.
