Warnings … Whether or not
It’s been an extremely warm week across all of Atlantic Canada. It’s interesting to note that very few record-high temperatures were set! Despite that, heat warnings have been on and off for various corners of the region for days.
When it comes to heat warnings there are two categories: those triggered by very warm air temperatures and those brought on by very high humidity levels. This week, the latter has been the case!
When it comes to criteria for issuing any type of warning, you’ll find regional variations. In the case of heat warnings, it stands to reason that the temperature threshold would not be the same in central Alberta as it would be in central Labrador.
Heat warnings are issued when the following conditions are forecast: NEW BRUNSWICK: Two consecutive days with daytime highs at or above 30 and overnight lows of 18 degrees or warmer
Or
Two or more consecutive days with a humidex reading of 36 or more.
NOVA SCOTIA:
Two consecutive days with daytime highs at or above 29 and overnight lows of 16 de- grees or warmer
Or
Two or more consecutive days with a humidex reading of 36 or WI-July 27-Weather U #CMYK more. PRINCE EDWARD ISLAND: Two consecutive days with daytime highs at or above 27 and overnight lows of 18 degrees or warmer
Or
Two or more consecutive days with a humidex reading of 35 or more. NEWFOUNDLAND AND LABRADOR:
Two consecutive days with daytime highs at or above 26 and overnight lows of 15 degrees or warmer
Or
Two or more consecutive days with a humidex reading of 34 or more.
Stay cool and hydrated and do your best to enjoy the summer; in less than five months, some of you will be taking down your Christmas tree.
