HALIFAX — Nova Scotians are being warned to prepare for an extended period of hot and sticky weather.
Starting today, the temperature is expected to rise to between 29 C and 32 C, but the humidity will make it feel much hotter than that.
Over the next three days, humidex values are expected to reach up to 40 in some areas, though it will feel cooler along the coast.
Heat warnings have been issued for the western half of the province.
Minimum overnight temperatures will dip to 18 C, but the humidity will remain high.
A cold front is expected to pass through the province late Friday.
Meanwhile, Environment Canada is warning people to watch for the effects of heat illness, which include swelling, cramps, fainting, a rash and heat exhaustion.
"Never leave people or pets inside a parked vehicle," the federal department said in a statement. "Outdoor workers should take regularly scheduled breaks in a cool place."
The Nova Scotia government is offering tips about how to stay healthy.
"It’s harder for our bodies to maintain a healthy internal temperature when it's hot and humid," the government said on its website. "Our bodies usually cool down by sweating, but sweating is less effective when it's humid."
Some people have a higher risk for developing heat-related illnesses, including infants, young children, seniors and people with chronic medical conditions, the Health Department said.
To prevent heat-related illnesses, people should drink plenty of water, stay in shaded or cool areas and wear lightweight clothing.
As well, residents should check on older neighbours and others vulnerable to heat-related illness and should offer air-conditioned shelter and water if needed, the department said.
