A hot airmass will continue to dominate Southern Ontario today. Daytime highs in the low thirties are expected again today. The hot weather conditions may ease somewhat in many places on Thursday, but may persist in the Greater Toronto area.
Watch for symptoms of heat illness, which include – dizziness or fainting, nausea or vomiting – headache – rapid breathing and heartbeat – extreme thirst and – decreased urination with unusually dark yellow urine. If you experience any of these symptoms during extreme heat, immediately move to a cool place and drink liquids. Water is best.
Frequently visit neighbours, friends and older family members, especially those who are chronically ill, to make sure that they are cool and hydrated.
Never leave people or pets in your care inside a parked vehicle or in direct sunlight.
