Heat warning in effect for all of P.E.I. on Wednesday and Thursday

A heat warning has been issued for all of Prince Edward Island, with temperatures soaring on Wednesday and Thursday and the weather feeling even hotter than the thermometer says.

Environment Canada forecasts maximum temperatures of 27 to 30 C on both days, with humidex values reaching up to 37. The overnight minimum temperature Wednesday will stay high, between 17 to 20 degrees.

"Tonight will still be a bit windy with cloudy periods possible, but the wind should be a touch lighter than last night, so my fingers are crossed for Charlottetown's Canada Day fireworks to get the green light tonight," said CBC meteorologist Jay Scotland.

Cooler conditions are expected along parts of the coast, with temperatures beginning to drop Thursday evening.

P.E.I.'s Chief Public Health Office offers the following tips to stay safe during extreme heat:

• Drink plenty of water throughout the day, even if you don't feel thirsty, and avoid alcohol and caffeinated beverages, which can lead to dehydration.
• Wear lightweight, loose-fitting, light-coloured clothing. A wide-brimmed hat and sunglasses provide added protection.
• Use sunscreen with SPF 30 or higher, and reapply it every couple of hours, or more often if swimming or sweating.
• Keep perishable foods refrigerated at temperatures below 4 C to prevent bacterial growth. When transporting perishable groceries, use insulated coolers with ice packs.
• Never leave anyone in a parked car, especially children and pets, even with the windows down.
• Find comfortable temperatures in indoor spaces like malls and libraries, or outdoor places like pools and beaches.
• Keep an eye on the local weather forecasts and heat advisories. Know the signs of heat-related illnesses and be prepared to act quickly if symptoms arise.

Calls to Charlottetown's fire department can go up during extreme weather events like heat waves, said Deputy Chief Kent Mitchell. 

He advised people to check on vulnerable residents over the coming days, including seniors and those with mobility issues. 

"We suggest [staying] in a cool type of area, don't exert yourself any more than necessary," Mitchell said. "If you're experiencing a personal emergency, please call 911 as soon as possible." 

Watch for the signs

Environment Canada says people need to watch for early signs of heat exhaustion, including headache, nausea, dizziness, thirst, dark urine, and fatigue. If symptoms arise, stop physical activity and drink water.

If you or someone else experiences heat stroke symptoms such as red, hot skin, dizziness, nausea, confusion or a change in consciousness, call 911 or contact your emergency health provider. While waiting for help, move to a cooler area, remove excess clothing and apply cold water or ice packs.
