Impact Level: Moderate

Forecast Confidence: High

This is a heat warning. Temperatures are high and there's a risk to public health. What: Daytime highs in the mid to high thirties combined with overnight lows in the high teens. When: Today to Thursday. Where: Okanagan Valley, Lillooet, South Thompson, Shuswap Additional information: Humidex values may approach the high thirties on Thursday over the Okanagan Valley and Shuswap as a southerly flow brings more moisture into the areas, increasing the humidity. 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.
