Action Day? No
Warm and sunny conditions are expected Sunday. Winds will be slightly stronger, helping to offset the warm and sunny conditions, but ozone will once again climb towards the upper Moderate AQI range downwind of the urban areas with lower Moderate AQI elsewhere. Steady winds on Monday along a pre-frontal trough developing along the I-95 corridor in addition to increasing cloud cover will keep ozone concentrations lower, with areas east of the mountains in the lower Moderate range, and Good air quality elsewhere. A cold front will move through the region Monday night giving way to cooler and breezy conditions on Tuesday. Most areas will remain in the Good AQI range.

Ground-level ozone is a real threat to our health because it reacts with sensitive lung tissue, causing harmful changes in breathing passages. Children, the elderly and individuals with respiratory diseases are especially harmed by ozone. Even healthy individuals can be harmed if they attempt strenuous activity on days with high ozone…those days should be used for inside low physical stress activity.
Remember, this may seem like a small contribution by you as an individual, but if we can get solid public involvement, working together we CAN make a real difference!
