Residents are being urged to take precautions as Environment Canada has issued a heat warning for Chatham-Kent and Rondeau Park, with a period of hot and humid weather expected to begin Wednesday and continue through at least Thursday.
Environment Canada forecasts daytime highs near 31 C, overnight lows around 21 C and humidex values ranging from 36 to 40. Forecast confidence is high for Wednesday and Thursday, while hot conditions could persist into Friday and Saturday, although confidence in the extended forecast remains lower. Areas near Lake Huron and Lake Erie are expected to be somewhat cooler.
Chatham-Kent Public Health warned that high temperatures and humidity can prevent the body from cooling properly, increasing the risk of heat-related illnesses such as heat exhaustion and heat stroke.
Symptoms of heat-related illness may include rapid breathing, dizziness or fainting, vomiting, a rapid heartbeat, extreme thirst and decreased urination accompanied by unusually dark yellow urine. Health officials advise anyone experiencing these symptoms to move to a shaded or air-conditioned area, drink fluids, rest and contact a health-care provider, friend or family member.
Heat stroke is considered a medical emergency. Public health officials said residents should call 911 immediately if someone has a high body temperature, is unconscious, confused or has stopped sweating.
Officials are encouraging residents to drink water regularly, seek cooler or air-conditioned spaces, avoid strenuous outdoor activities during the hottest part of the day and wear lightweight, loose-fitting clothing. Residents are also reminded never to leave children, other people or pets unattended in parked vehicles.
Friends, family members and neighbours are being asked to check on older adults, people living alone and others who may be vulnerable to extreme heat. Public health officials noted that homes without air conditioning can become dangerous during prolonged heat events because overnight temperatures may not cool sufficiently.
Municipal centres, libraries and Hope Haven in Chatham are available as cooling locations. Hope Haven, located at 183 Wellington St. W., is open daily from 10 a.m. to 2 p.m. Homeless individuals and others lacking adequate shelter, food or water are considered particularly vulnerable during extreme heat. Support is available through the Homeless Response Line at 519-354-6628.
Environment Canada advises residents to continue monitoring forecasts and alerts as conditions evolve through the week.
