Ozone will be highest during the afternoon and early evening hours when sunshine is most abundant, and temperatures are highest. Ozone will be low in the morning, late evening, and overnight. Another alert is possible on Tuesday afternoon as sunny skies and heat persist. PRECAUTIONARY/PREPAREDNESS ACTIONS...
