FORT ST. JOHN -- Heat warnings for the BC Peace Region and Fort Nelson are expected to remain in effect until at least Wednesday night, according to Environment and Climate Change Canada.

The weather agency said the high temperatures are considered a “moderate risk to public health.” Daytime highs are expected to be in the low 30s, while overnight lows will hover around 16 C.

“A strong ridge of high pressure over the region will continue to result in very high temperatures. These temperatures are expected to moderate starting Thursday,” the warning said

“Daytime high temperatures are expected to moderate to the mid to high 20's starting Thursday, but warm weather will likely persist.”

“Watch for early signs of heat illness (feeling unwell, fatigue, thirst, headache, unusually dark urine) as these can rapidly evolve into life-threatening emergencies,” the weather agency says.

Warnings are in effect for dozens of regions across the province.

The BC Wildfire Service says the stretch of hot and dry weather brings an elevated risk for new fires to start and is urging everyone to heed fire bans and to report wildfires or risky activity by calling 1-800-663-5555 or *5555 on a cell phone.
