Southern Manitoba is heading into its hottest stretch of the summer so far, with humidex values expected to reach a sweltering 40 degrees by Friday, prompting a heat warning across the region.
Environment Canada says a hot and humid air mass will settle over the area beginning on Thursday, making for uncomfortable and potentially dangerous conditions. Relief is expected late Friday night as a cold front moves through, bringing slightly cooler and less humid weather by Saturday.
Local health officials and emergency services are urging residents to take precautions to protect themselves and others, particularly vulnerable individuals such as seniors, young children, and people with pre-existing health conditions.
Warning signs
Heat-related illnesses can creep up quickly. Early signs of heat exhaustion include headache, nausea, dizziness, dark urine, and extreme fatigue. If you or someone you’re with experiences these symptoms, it’s important to stop any physical activity immediately, move to a cool place, and drink plenty of water.
Heat stroke is a medical emergency and can be life-threatening. Symptoms include red, hot skin, confusion, nausea, and a possible loss of consciousness. If someone is showing these signs, call 911 right away and try to cool them down with cold water or ice packs while waiting for help.
Tips to stay safe
To help manage the heat, health authorities recommend the following:
- Drink water regularly, even before you feel thirsty
- Close curtains and blinds during the hottest parts of the day to keep indoor temperatures down
- Use fans or air conditioning, or head to a cooler public space such as a library, community centre, or shaded park
- Avoid outdoor activities during peak heat hours, typically between 11 a.m. and 4 p.m.
- Dress in loose-fitting, light-coloured clothing and wear a wide-brimmed hat if you’re outdoors
- Never leave children or pets in a parked vehicle, and always double-check before locking up
With many in the Portage la Prairie area heading outdoors to enjoy summer, authorities are reminding everyone to plan accordingly and avoid overexertion during the heat of the day.
