Heat warnings and special weather statements have been lifted across British Columbia, but remain in place in large parts of the Yukon as temperatures across the territory top 30C, eight degrees above the mean.

Heat warnings are posted for the Dawson, Mayo and Pelly-Carmacks areas northwest of Whitehorse.

The weather office says the warnings are expected to be lifted later today, but special weather statements cover areas as far north as Old Crow, with temperatures of up to 28 degrees forecast through the weekend .

The watches, warning of potentially damaging hail, strong winds and torrential rain, cover areas with flood warnings and watches in effect for sections of the Quesnel, Thompson and South Thompson rivers, including Shuswap Lake .

The River Forecast Center says waterways have peaked in most areas as recent heat has supported late snowmelt, but it warns levels are high and will be vulnerable to storm-related runoff.

The thunderstorm watches cover the Cariboo, North Thompson and 100 Mile regions south of Shuswap, Okanagan, Arrow and Slocan lakes and the center says these areas are being closely watched.

“Precipitation and potential thunderstorms over regions Tuesday through Wednesday could lead to increased runoff,” the center said.

“For rivers and lakes at or near capacity, this may result in further increases in levels on Tuesday and Wednesday.”
