Heat Wave in Canada on July 31 2016 03:19 PM (UTC).
Red hot heat warnings cover most of southern Manitoba on Sunday. The warnings extend from the U.S. and Saskatchewan borders, as far east as Beausejour and Steinbach, and up into the Interlake and Parkland Region. Daytime highs across southern Manitoba will reach around 30 Celsius. With humidex values of close to 40 Celsius, the risk of heat-related illnesses, including heat stroke and heat exhaustion, is increased. Environment Canada warns older adults, infants and young children, people with chronic illnesses, who work or exercise in heat, homeless people, and people without access to air conditioning, to take extra precautions against the heat. Be sure to drink lots of liquid and protect yourself from the sun. The UV Index in Winnipeg is 8, or very high. The high heat and humidity also make it possible we could get a thunderstorm later in the day. The heat should break after Sunday, with some showers ending in the morning, and then a risk of more showers or even a thunderstorm in the afternoon. Tuesday will be sunny and hot again, but we could get another day of showers Wednesday before the skies clear again. The rest of the week heading into the weekend should be hot and sunny.
