Yet another heat wave is hitting Sarnia-Lambton with the announcement by Environment Canada that humidex values reaching near 40 degrees C are expected Tuesday, with high temperatures reaching near 32 degrees until Thursday.

Night time lows will also be warm in the 19 to 21 degree range Tuesday and Wednesday nights. There may be temporary relief from the heat due to showers or thunderstorms. Cooler weather will arrive by Friday.

Members of the public are asked to frequently visit neighbours, friends and older family members, especially those who are chronically ill, to make sure that they are cool and hydrated.

Never leave people or pets in your care inside a parked vehicle or in direct sunlight.

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.

Please continue to monitor alerts and forecasts issued by Environment Canada. To report severe weather, send an email to or tweet reports to #ONStorm.
