VANCOUVER — Environment Canada has issued heat warnings for a swath of British Columbia's Interior stretching from Grand Forks near the U.S. border to areas north of Prince George.
The weather office says the heat is expected to arrive with a ridge of high pressure on Tuesday and persist until at least Thursday.
The bulletin for the Okanagan Valley, Fraser Canyon, South Thompson, Boundary and West Kootenay regions says temperatures are expected to hit between 35 C to 37 C with overnight lows near 18 C.
The North Thompson, Cariboo, Prince George and Stuart-Nechako areas are expected to see temperatures between 29 C and 34 C, with overnight lows of around 14 degrees.
The BC Wildfire Service says there is also a "significant chance" of dry lightning across the province this week.
The latest bulletin from the service says the combination of heat, drying forest fuels and dry lightning will raise the risk of new wildfires starting.
"Fortunately, winds are expected to remain light and variable, and this pattern is anticipated to shift eastward later in the week," the service says.
The weather office is encouraging people to watch for signs of heat illness, including fatigue, headache and thirst, and to check in on family, friends and neighbours who are at higher risk during hot weather.
It says the risks are greater for seniors, people who live alone, those with health or mental-health conditions and people with limited mobility.
