Heat Warning Issued for Huron and Perth Counties

Huron Perth, ON - Environment Canada has issued a heat warning for much of southern Ontario, including Huron Perth.  A heat event is forecast for Tuesday and Wednesday (June 21 and 22). Daytime temperatures are expected to reach low to possibly mid 30 degrees Celsius.

Temperatures Tuesday night and Wednesday night are expected to be in the low twenties, providing little relief from the heat.  Hot and humid conditions may also lead to poor air quality.  Cooler air is expected to arrive by Thursday, June 23.

Heat warnings are issued when high temperature or humidity conditions reach criteria established by Environment Canada and are expected to pose an elevated risk of heat-related illnesses, such as heat stroke or heat exhaustion.  While extreme heat affects everyone, the risks are greater for young children, pregnant individuals, older adults, people with chronic illnesses, people experiencing homelessness, and people working or exercising outdoors.

Huron Perth Public Health reminds people to take measures to avoid heat-related illnesses, such as:

  • Drink plenty of cool liquids, especially water, before you feel thirsty to decrease your risk of dehydration. You may be dehydrated before you start feeling thirsty.
  • Reschedule or plan outdoor activities during cooler parts of the day.
  • Wear loose-fitting, light-coloured clothing made of breathable fabric.
  • Never leave people or pets inside a parked vehicle or in direct sunlight.
  • Take a break from the heat by spending a few hours in a cool place, such as a tree-shaded area or air-conditioned space.
  • Take cool showers or baths until you feel refreshed.
  • Prepare meals that don’t need to be cooked in your oven.
  • Block sun out by closing curtains or blinds during the day.
  • Avoid sun exposure. Shade yourself by wearing a wide-brimmed, breathable hat or using an umbrella.

Heat-related illnesses include heat stroke, heat exhaustion, heat fainting, heat edema (swelling of hands, feet and ankles), heat rash and heat cramps (muscle cramps). Watch for symptoms of heat illnesses, which include:

  • Dizziness or fainting
  • Nausea or vomiting
  • Headache
  • Rapid breathing and heartbeat
  • Extreme thirst
  • Decreased urination with unusually dark yellow urine.

If you experience any of these systems during extreme heat, immediately move to a cool place and drink liquids. Water is best.

Symptoms of heat stroke include high body temperature, confusion, being unconscious or stopping sweating. Heat stroke is a medical emergency. Call 911 or your local emergency number immediately if you are caring for someone with these symptoms.While waiting for help, cool the person right away by:

  • Moving them to a cool place, if you can
  • Applying cold water to large areas of the skin or clothing
  • Fanning the person as much as possible.

Check in on neighbours, friends and older family members, especially those with chronic illness, to make sure they are cool and hydrated.
