Excessive heat and humidity continues today into tonight. Afternoon temperatures near 31 degrees and humidex values near 40 are expected again today. An overnight low near 21 degrees is forecast tonight. Slightly cooler and less humid air is forecast for Wednesday. Hot and humid air can also bring deteriorating air quality and can cause the Air Quality Health Index to approach the high risk category.
Extreme heat affects everyone. The risks are greater for young children, pregnant women, older adults, people with chronic illnesses and people working or exercising outdoors. Drink plenty of water even before you feel thirsty and stay in a cool place. Reduce your heat risk. Schedule outdoor activities during the coolest parts of the day. Never leave people or pets inside a parked vehicle. Outdoor workers should take regularly scheduled breaks in a cool place.
