A late season heat event has hit the City of Hamilton today on the first day of autumn.
Environment Canada issued a heat WARNING for Hamilton as of 3:28pm on Friday afternoon.
Hot and humid conditions continue today.
Mostly sunny skies will allow daytime temperatures to reach the low thirties, with humidex values approaching forty again today.
A cold front is expected to move across Southern Ontario through the day Wednesday bringing cooler temperatures by Thursday.
Watch for the effects of heat illness: swelling, rash, cramps, fainting, heat exhaustion, heat stroke and the worsening of some health conditions.
Drink plenty of water even before you feel thirsty and stay in a cool place.
Seek a cool place such as a tree-shaded area, swimming pool, shower or bath, or air-conditioned spot like a public building.
Never leave people or pets inside a parked vehicle.
Hot and humid weather conditions are creating elevated pollution levels.
Environment Canada also issued A SPECIAL AIR QUALITY STATEMENT which has since ended due to the possibility of deteriorating air quality. Light winds and stagnant weather conditions have resulted in increasing levels of fine particles, nitrogen dioxide and ozone in the above regions. High risk AQHI values are expected to persist for a few hours this evening.
Individuals may experience symptoms such as increased coughing, throat irritation, headaches or shortness of breath. Children, seniors, and those with cardiovascular or lung disease, such as asthma, are especially at risk.
Exposure to air pollution is particularly a concern for children, the elderly, and those who have underlying medical conditions such as lung or heart disease.
