With temperatures forecasted to reach 35 C on Thursday, Aug. 1, Environment Canada has issued a heat warning to the majority of the Okanagan region.

"A strong ridge of high pressure is building over the region," said Environment Canada's statement. "The above average heat is expected to persist until the end of the weekend at which time the ridge will break down and temperatures will cool."

The warning, which was issued at 4:38 a.m., covers the South Okanagan, extends through the Central Okanagan, and reaches Armstrong. Salmon Arm, Sicamous, and Revelstoke are not under the heat warning. 

Environment Canada reminds the public to watch out heat-related illnesses like heavy sweating, cramps, fainting, rash, a higher body temperature and the worsening of some health conditions. Long exposure in the heat can cause heat stroke. 

Young children, pets, and people susceptible to the heat should not be left inside vehicles. 

Those who have been in the heat too long or in an over-heated area should find a shaded area, an air-conditioned spot, or a place with a misting station. 

The heat warning also covers the South Fraser Canyon, Manning-Skagit Valley, South Thompson, Kootenay Lake, and East Kootenay.
