Heat warning issued as 'excessive humidity' continues Tuesday

London, Ont. -

Environment Canada has issued a heat warning for London and surrounding regions as 'excessive heat and humidity' continues into Tuesday night.

The weather agency issued a special weather statement Monday due to the heat and humidity but has since upgraded it to a full warning.

In London, afternoon temperatures are expected to get to near 31 C but feel more like 40, meanwhile the overnight low will only drop to 20 C.

Slightly cooler and less humid air is expected Wednesday.

Warnings are issued because extreme heat can be dangerous especially for vulnerable populations such as newborns or the elderly.

It is advised that family check on those who might be particularly vulnerable to the heat.

Other tips to remember are to stay hydrated, limit outdoor activities to cooler points in the day, don’t leave children or pets in a parked vehicle, and don’t leave children or pets outside for a long period of time.

Warnings are in place across southwestern Ontario and eastward towards the Niagara region.

The Middlesex-London Health Unit has also issued a one-day heat alert for Tuesday due to the high heat and humidity.

Anyone spending time outdoors is encouraged to wear sunscreen, a hat and drink plenty of water.
