A heat warning is in effect for parts of B.C.’s Southern Interior.
Environment Canada says temperatures could reach 40 C in the South Thompson and Fraser Canyon regions, courtesy of a ridge of high-pressure building over Southern B.C.
The national weather agency says temperatures are expected to peak on Sunday and Monday, with the mercury hitting the high 30s on Sunday and possibly reaching 40 at Lytton.
“Overnight (into Monday), temperatures will only cool to the upper teens, and may in fact stay above 20 in windier locations of the Fraser Canyon,” said Environment Canada, which is forecasting highs into the mid-30s for Monday and Tuesday.
The heat warning is also in effect for the Cariboo, where temperatures are expected to reach into the low 30s.
