Figure 1. Daily counts of mortality (bars) and the
population-weighted maximum daily temperature (blue line) for 2021 (top
left) and 2012-2020. Bars are colored corresponding to their
statistical deviation from the expected daily number of deaths (black
line) calculated using the Public Health Intelligence for Disease
Outbreak (PHIDO) algorithm which is used by the British Columbia Centre
for Disease Control to detect anomalies. The extreme heat event (EHE)
was defined as the period when there was significant excess mortality
(orange and red bars) in the province (25 June – 02 July 2021).
