June 22 has been determined a Code Orange Air Quality Action Day for Delaware.
Weak high pressure overhead will bring mostly sunny skies and temperatures nearing 90 degrees Fahrenheit. Calm morning winds will become light southwesterly by midday. This will allow pollutants to accumulate through the morning hours. Westerly flow aloft combined with clear skies, above average temperatures and limited vertical mixing will bring ozone into the code orange range. Particles will rise into the moderate range in response to the light southwesterly winds.
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 739-6619. Other questions should be directed to the Division of Air Quality at 739-9402.
