Possible record daily high in Grande Prairie prompts call for caution in heat, Lethbridge vulnerable too

Jul 27, 2020 | 2:18 PM

With the possibility of having a record-breaking temperature on Monday in Grande Prairie, a meteorologist with Environment and Climate Change Canada is warning the public to be cautious, and to look out for others.

The forecast for July 27, 2020, calls for a high of 32 degrees. The previous record high temperature for that day was set in 1932 when the temperature was recorded at 30.6 degrees.

The most recent hottest July 27 was recorded in 2009 when the mercury rose to 29.2 degrees.

In Southern Alberta, we can expect daily highs to be in the 30’s all week, but it likely will not be enough to break records in Lethbridge.

For example, the high for Tuesday, July 28 is 33 degrees. The highest temperature recorded on a July 28 in the city was in 1939 with a recorded heat of 38.9.

Despite being on opposite ends of the province, the precautions from Environment Canada remain the same.

Natalie Hasell, a Warning Preparedness Meteorologist, says, though everyone can be affected by the heat, there are certain people who are more at risk of heat illnesses like heat stroke or heat exhaustion. Those include the elderly, infants, the homeless, and those will previous medical issues.

“There are chronic illnesses like breathing problems, kidney issues, diabetes, cardiovascular, that can make one more susceptible to heat illness. You might see symptoms get worse, or you might see other symptoms than those associated with heat illness become particularly bad.”

She adds that those with mental health issues may also see adverse effects from the heat, but not necessarily because of their condition, and instead because of their medication. She says people should talk to their pharmacists, and find out what sort of side effects their medication could have, and how it may make someone more susceptible to things like the heat.

Hasell says those that work or exercise in the heat should also be cautious, and take some steps to make sure they’re not over-exposed. She says strenuous outdoor activity should be avoided, but if necessary, then have plans to take breaks in cool and shaded areas that are long enough to sufficiently cool down, and to drink lots of water.

The public is asked to look out for those most vulnerable nearby, whether they are friends, family members, or neighbours. She also warns not to leave children or pets inside vehicles, as the temperatures inside can be substantially hotter than those outside.
