Environment Canada is calling for hot, humid weather in London, Komoka, Parkhill and Strathroy as well as eastern and western Middlesex County.
A heat warning remains in place for the region. Environment Canada issued the warning on Labour Day Monday, calling for humidex values peaking in the low 40s and daytime highs reaching 31 degrees. Nighttime lows will offer little relief from the heat, with temperatures dipping to just above 20 degrees.
A chance of scattered showers and thunderstorms will accompany the heat until Wednesday.
The national weather agency is predicting this hot, humid weather will cool off Wednesday night, when a cold front is expected to roll through the region.
On top of the heat warning, the Middlesex-London Health Unit is issuing a one-day heat alert for Tuesday, the health unit’s sixth heat alert of the year, as forecasters call for daytime highs of 32 degrees, feeling like 44 degrees.
Until cooler weather prevails, Environment Canada advises residents not to leave people or pets in parked cars.
Young children, pregnant women, older adults, people with chronic illnesses and people working or exercising outdoors are at greater risk for heat-related health issues.
