P.E.I. heat warning enters 2nd day | CBC News

Prince Edward Island remains under a heat warning, and while that warning is forecast to end Wednesday, Islanders may not see any real heat relief until the weekend.

Environment Canada issued the heat warning Sunday. Heat warnings are issued for P.E.I. when daytime highs are expected to exceed 28 C, and nighttime lows are forecast to remain above 18 C.

The temperature at Charlottetown Airport peaked just over 29 C Monday and barely dropped below 20 C overnight.

Again on Tuesday the temperature is expected to reach 29 C with the overnight low falling only to about 19 C overnight. CBC meteorologist Jay Scotland said Islanders might, in a few places, find some relief along the shore.

“You may see a spot or two that’s a smidge cooler if you’re near the water and the wind’s coming in off the water,” said Scotland.

“But for the most part, 99 per cent of P.E.I. will again be contending with temperatures 25 to 29, humidex values mid to high 30s.”

There is a risk of thundershowers starting late in the afternoon and continuing through to about midnight.

Those potential thundershowers, however, will not do a whole lot to knock back the heat.

Daytime high temperatures are forecast to hit 26 C Wednesday, Thursday and Friday, with overnight lows remaining above 20 C both Thursday and Friday nights.

During the heat warning Islanders should guard against heat exhaustion and heat stroke.

Avoid physical activity outside during the heat of the day, and drink lots of water.

Temperatures well above normal for a month

The temperature is not forecast to fall below normal until Saturday, with a high of 22 C.

This is P.E.I.’s second heat wave in recent weeks.

On June 19 and 20 daily high temperature records toppled across the province. The 32.0 C recorded at Charlottetown Airport brushed against the 32.2 C record for the hottest day ever in June.

The last 30 days in Charlottetown have been 2 C above normal, as measured from 1981 to 2010.
