A heat warning remains in effect for parts of northwestern Ontario as hot and humid conditions continue through Thursday.

Environment Canada says the yellow level warning shows that daytime highs will reach 29 to 31 C, with humidex values ranging from 33 to 38. Warm overnight temperatures will provide little relief, and some areas could see the heat linger into Friday.

Residents are encouraged to stay hydrated, limit strenuous outdoor activities, and check in on older adults and other vulnerable people. Meteorologists also warn that air quality could deteriorate as the heat continues.

Temperatures are expected to soar in parts of Nova Scotia, Tuesday, with our first heat warning of the season.

It includes Lunenburg County, Queens County, and the Annapolis Valley.

Highs near 30 degrees are expected Tuesday afternoon but will feel like 35; and the heat is set to persist into Wednesday.

Environment Canada Meterologist Ian Hubbard tells us it’s the first heat wave of this nature in Nova Scotia for the month of May, since they changed the criteria in 2018.

“We look for two consecutive days of temperature reaching 29 degrees or more,” says Hubbard. “We also have an overnight temperature in there and it has to stay above 16.”

Hubbard says, they also look at humidex value.

“If we see consecutive days of the humidex reaching 36 or higher, we would issue a heat warning for that as well,” explains Hubbard.

As for the Halifax area, temperatures will peak at 24 degrees Tuesday and 30 degrees Wednesday – not quite high enough for a warning.

Conditions may be slightly cooler along coastal areas.

The forecaster encourages to watch for signs of heat exhaustion that may include headache, nausea, dizziness, thirst, dark urine, and intense fatigue.
