Calgary hit an all-time record high on Friday when the thermometer climbed to 36.5 C which eclipsed the previous record of 36.1 C set 85 years ago.

Environment Canada had issued heat warnings for more than 100 regions in Alberta, British Columbia, Saskatchewan and Manitoba.

Besides the heat, smoke from forest fires have caused poor air quality throughout Western Canada.

A cold front lowered temperatures in Alberta to near seasonal values for the weekend but the heat lingered in the eastern Prairies.

The heat returns!

Another round of very warm temperatures and high humidity has enveloped almost all of the Maritimes with only New Brunswick’s Fundy coast exempt from an Environment Canada heat warning.

While actual daytime highs will approach 30 C, humidex values will range between 35 and 40 which can be dangerous for those at risk including young children, seniors and anyone with a chronic illness.

Forecasters say some relief may come on Thursday with some much needed rain but high humidity could persist until early next week.

Chris could pose threat

Chris

Atlantic Canada could feel an impact from Tropical Storm Chris which has formed off the coast of the Southeastern U.S.

The Canadian Hurricane Centre says the third named storm of 2018 will move northeastward and possibly strengthen to become a hurricane by early Wednesday.

The storm could weaken as it approaches Nova Scotia by Thursday.

The CHC notes there is still uncertainty in the forecast track and intensity of this system.

Beryl is the second named storm but first hurricane of the season and has been down downgraded to a tropical storm as it heads toward Puerto Rico.

Meantime, Environment Canada issued another heat warning for New Brunswick except the Fundy coast, Prince Edward Island and northern Nova Scotia as a warm, humid air mass pushes highs into the low 30s C with humidex values up to 38 on Monday.

Heat warning!

Record highs could be broken in Greater Moncton over the next couple of days if forecast highs in the low to mid 30s C are reached on Tuesday and Wednesday.

Environment Canada has issued a rare heat warning for New Brunswick, mainland Nova Scotia and Prince Edward Island with cooler conditions along the coast.

A warm, humid airmass is expected to push humidex values about 40 during the day and barely falling below 18 C at night – dangerous levels for those susceptible to heat.

Forecasters believe warm, humid weather will persist until later this week when a cold front brings temperatures closer to normal for the weekend.

This may have been the first weekend of autumn in Southeast New Brunswick but it felt more like the first weekend of summer instead.

Greater Moncton climbed to 27.7 C yesterday (23 September) while today (24 September) it hit 27.9 C and the normal high for late September is 17 C.

High pressure and a northerly jet stream has pushed heat across Eastern Canada with highs in the low 30s C in many parts of Ontario and Southern Quebec.

A heat warning was in place as Toronto Pearson Airport reached a record-breaking 33.1 C yesterday and 33.6 C today.

Weather watches, warnings, statements re: heat and thunderstorms, 08 July 2017 (Environment Canada)

A strong ridge of high pressure over Western Canada has pushed the thermometer into record high territory for British Columbia and Alberta.

On 07 July, dozens of communities set new maximum temperatures with the highest at 39.4 C in Warfield and 38.3 C in Nelson but the hot spot in Canada was Garden River in northern Alberta at 40.3 C.

The major cities were warm too with Calgary reaching 33 C and Edmonton 30 C.

Heat warnings have been issued for most of Alberta and parts of Saskatchewan where temperatures will be near 29 C or higher for the next few days and residents are urged to take precautions.

For the first time this summer, Environment Canada has issued a heat warning for Greater Moncton and Southeast New Brunswick.

Humidex values between 35 and 40 degrees are being experienced inland across much of New Brunswick today.

Conditions are expected to persist this afternoon and then gradually diminish this evening as temperatures drop in the low 20’s overnight.

Another period of hot and humid weather is expected for Wednesday before subsiding at night.

Drink plenty of liquids especially water before you feel thirsty to decrease your risk of dehydration.

Heat warnings are issued when high temperatures or humidity are expected to pose an elevated risk of heat stroke or exhaustion.
