A heat warning is in effect for parts of southwest Manitoba.

Temperatures in the area are forecast to be about 32 C today but hot and humid conditions will push the humidex values into the 40s, according to Environment Canada.

Heejune Chang, a public health doctor with the Winnipeg Regional Health Authority, said people working or playing outside need to be extra careful, because they are at a higher risk for heat stroke. 

"Make sure you stay well hydrated, take a rest, whenever you need it, go to the shade whenever you need it, in spite of what you may be doing, your own health is extremely important."

Older adults, infants, young children and anyone with a chronic illness are advised to take extra precautions from the heat and be sure to drink plenty of liquids.
