Niagara residents are being urged to take care in the heat as Environment and Climate Change Canada issued an orange alert for extreme temperatures across the region over the next few days.
The warning comes just ahead of the July 1 holiday, when many people are expected to spend time outdoors at celebrations and events across St. Catharines, Niagara Falls, Welland and surrounding communities.
According to a Niagara Region Public Health news release, the health unit is reminding people to take precautions to protect themselves, their families and their neighbours during the extended heat event.
"Prolonged periods of high temperatures and humidity can increase the risk of heat-related illness," the release states, pointing to several groups who face heightened danger in the heat.
Those most at risk include people experiencing homelessness, older adults, infants and young children, people with chronic health conditions, people who are pregnant, anyone without access to air conditioning, and those whose jobs or activities keep them outside for long stretches.
Residents are advised to know the warning signs of heat-related illness. Symptoms can include headache, dizziness, nausea, heavy sweating, muscle cramps, confusion or fainting.
Anyone experiencing these symptoms should take them seriously, as heat illness can escalate quickly when temperatures and humidity remain high for several days in a row.
The health unit is directing residents to Niagara Region's High Heat webpage for information on staying safe during extreme temperatures. That resource includes guidance on recognizing and responding to heat-related illness.
For the most current status of the heat alert, residents can check Environment Canada's weather information page or download the WeatherCan app, which pushes alerts directly to mobile devices.
The timing of the alert is notable, with Canada Day falling tomorrow and outdoor gatherings, parades and fireworks typically drawing large crowds across the region.
People planning to be outside for the holiday are encouraged to monitor conditions and check on family members, friends and neighbours who may be more vulnerable to the heat.
The alert is expected to remain in effect over the coming days, and residents are advised to stay informed as forecasts are updated.
