Thursday, May 3rd, will be a Code Orange Air Quality Action Day for Delaware!

An early season air quality event is underway across the northern Mid-Atlantic region. Ozone has risen dramatically on Tuesday, much faster than expected, given the still relatively low temperatures by summer standards. The air mass in place appears to be quite polluted, with dilute smoke present from fires burning upwind across the southeastern U.S., which is fueling ozone formation. Wednesday will be warmer than Tuesday, with temperatures reaching into the mid-80s °F. Humidity will remain quite low, with clear skies allowing strong May solar radiation to promote rapid ozone formation. The only potentially limiting factor is breezy afternoon winds, but given the other ozone-conducive conditions in place, the uptick in afternoon atmospheric mixing is not expected to be enough to prevent daily ozone from reaching the Code Orange range.

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.
