Heat Warning in effect for:Temperatures reaching 35 degrees Celsius combined with overnight lows near 18 degrees Celsius are expected for the next 3 days.
This is a heat warning. Temperatures are very high and there is a moderate risk to public health.
What: Temperatures reaching mid 30s combined with overnight lows near 18 degrees Celsius.
When: Now through Thursday.
Where: Fraser Canyon, South Thompson, and Boundary.
Remarks: A ridge of high pressure anchored over B.C. is bringing very high temperatures to the region this week.
Heat affects everyone, but the risks are greater for: seniors, people who live alone, people with pre-existing health conditions such as diabetes, heart disease or respiratory disease, people with mental illness such as schizophrenia, depression, or anxiety, people with substance use disorders, people with limited mobility.
Check on family, friends and neighbours, who are at higher risk, particularly if they live alone, to make sure they have a cool space.
Watch for early signs of heat illness (feeling unwell, fatigue, thirst, headache, unusually dark urine) as these can rapidly evolve into life-threatening emergencies.
Move to a cooler environment immediately, such as a shaded or air-conditioned space.
Drink plenty of water regularly, even before you feel thirsty to decrease your risk of dehydration. Thirst is not a good indicator of dehydration.
Never leave susceptible people, particularly children, or pets inside a parked vehicle.
If you are in an overheated area, seek a cool place such as a tree-shaded area, splash pad, misting station, or air-conditioned spot like a public building.
