Heat Warning issued for Lambton County

Point Edward, ON – With the prediction of hot and humid weather expected for Monday, June 28 and Tuesday, June 29, Environment and Climate Change Canada is issuing a Heat Warning for Lambton County. 

The warning will remain in effect until Wednesday, June 30 when conditions are expected to ease.

A heat warning is issued when two consecutive days are forecast to have a daytime high temperature greater than or equal to 31⁰C, and a nighttime temperature greater than or equal to 20⁰C or a humidex greater than 40⁰C. In high temperatures and humidity, your body may not be able to cool properly which can lead to heat exhaustion or even heat stroke.

“The elderly, very young and people with chronic illnesses are at higher risk of experiencing a heat-related illness,” said Dr. Sudit Ranade, Medical Officer of Health. “However, even healthy people can be affected if they participate in strenuous activities, and do not take precautions.”

Symptoms of heat-related illnesses may include: rapid breathing, dizziness or fainting, vomiting, rapid heartbeat, extreme thirst and decreased urination that is unusually dark yellow in colour. If you are experiencing these symptoms, please move to a shaded or air conditioned area, drink plenty of fluids, and rest. If symptoms persist, please contact your healthcare provider, a family member or friend.

Heat strokes are considered a medical emergency. Call 911 immediately if you are caring for someone who has a high body temperature, is unconscious, confused or has stopped sweating. Friends, family and neighbors should check on those who may be vulnerable and need help to keep cool or take other preventative actions.

Heat-related illness is preventable

  • Drink plenty of fluids, especially water;
  • Avoid strenuous activities between 11:00 a.m. and 3:00 p.m. when the sun’s rays are strongest. Re-schedule outdoor activities to a cooler time of day.
  • Avoid going out in the sun, if possible. If you are outdoors, seek shade and wear sunscreen. Wear light-weight, loose fitting clothing and sunglasses;
  • If you are taking medication or have a health condition, ask your healthcare provider if the heat increases your health, and follow their recommendations;
  • Call elderly family members, neighbors, persons with disabilities, and persons with chronic illnesses daily to make sure they are keeping cool and hydrated;
  • Take cool showers or baths, or use cool, wet towels on your face, neck or arms;
  • The use of a fan alone may not provide enough relief from the heat. Avoid heavy meals and using your oven. Keep curtains closed to block the sun during the day;
  • Never leave anyone (including pets) in a parked car. Pets need a cool location and fresh water.
