VANCOUVER — Temperatures in British Columbia have hit all-time Canadian record levels for the month of September for the second consecutive day, as extremely hot and smoky conditions persist across much of the province.

The mercury hit a new record of 40.8 C in Cache Creek on Wednesday (Sept. 3), a day after Lytton matched the 40 C record that had previously been set in Manitoba. Lytton also set a new record on Wednesday with a temperature of 39.8 C.

The two Fraser Canyon communities were among 16 in B.C. that set daily heat records on Wednesday.

A new record was also set in Kamloops 36.9, a mark which shattered the old record of 34.5 C set in 1988, with records going back to 1890. The communities of Clearwater (36.4 C), Clinton (34.3 C), Lillooet (38.7 C), and Merritt (38.7 C) also set new daily records on Wednesday.

More than 30 air-quality alerts meanwhile cover much of B.C., and there are six heat warnings in place in areas including the Fraser Canyon, the Thompson region, Boundary and 100 Mile.
