Toronto, Hamilton, and Southern Ontario Sizzles
THUNDER BAY – WEATHER – If you are jumping on Porter, Westjet or Air Canada and headed to Toronto, make sure you are ready for the weather today. Environment Canada has a Heat Advisory in effect for Toronto and Hamilton.
A hot and humid airmass will affect portions of southwestern Ontario and the Golden Horseshoe today. Humidex values near 40 are forecast for this afternoon and high temperatures of 30 degrees Celcius are expected. A cold front will sweep across the regions this evening bringing a return to near seasonal temperature values for the remainder of the week.
While extreme heat can put everyone at risk from heat illnesses, health risks are greatest for
– older adults
– infants and young children
– people with chronic illnesses such as breathing difficulties, heart conditions or psychiatric illnesses
– people who work in the heat
– people who exercise in the heat
– people without access to air conditioning and
– homeless people.
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.
Drink plenty of liquids especially water before you feel thirsty to decrease your risk of dehydration. Thirst is not a good indicator of dehydration.
