Hot and humid conditions are expected to blanket the London region through the weekend.
On Wednesday, Environment Canada issued another heat warning for London, Middlesex, Strathroy, Parkhill, and Komoka.
The national weather agency says the heat wave is expected to start on Thursday as temperatures climb into the lows 30’s.
Heat warnings are issued when very high temperature or humidity conditions are expected to pose an elevated risk of heat illnesses, such as heat stroke or heat exhaustion.
The Middlesex-London Health Unit has also issued an extended heat warning for the region.
Officials says you should watch for symptoms of heat illness, including dizziness or fainting, nausea or vomiting, headaches, and rapid breathing and heartbeat.
Environment Canada say if you plan on being outside make sure to drink plenty of liquids especially water before you feel thirsty to decrease your risk of dehydration.
The national weather agency urges you to visit neighbours, friends and older family members, especially those who are chronically ill to make sure that they’re cool and hydrated.
Officials are reminding you to never leave people or pets in your care inside a parked vehicle or in direct sunlight.
