A hot and humid airmass will affect portions of southwestern Ontario and the Golden Horseshoe today.

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.

Heat warnings are issued when very high temperature or humidity conditions are expected to pose an elevated risk of heat illnesses, such as heat stroke or heat exhaustion.

Environment Canada meteorologists will update alerts as required, so stay tuned to your local media or Weatheradio. Email reports of severe weather to [email protected] or tweet with the hashtag #ONStorm.
