The Middlesex London Health Unit (MLHU) has issued a one-day heat alert that will remain in effect until Tuesday morning.
The Environment Canada forecast for Monday afternoon in the London, Ont., region calls for a spike in temperatures, with an expected high of 31 C, feeling closer to 33 C with humidex values.
Overnight temperatures are expected to drop to 21 C with Tuesday looking at a potential high of 27 C.
While rain is projected to fall later Monday, MLHU says the temperatures are still within the health unit’s criteria to issue a one-day heat alert.
According to a MLHU media release, heat alerts are declared when Environment Canada issues a forecast with a daytime high of 31 C or higher with an overnight low of 20 C or higher, or a forecast calling for a humidex of 40 C or higher.
The health unit recommends staying hydrated, planning outdoor activities in the early morning and evening, and keeping out of direct sunlight for extended periods of time to prevent heat-related illnesses.
MLHU also advises parents to never leave a child or pet in a parked car or sleeping outside in direct sunlight.
