Today's hot and humid weather has pushed Hamilton into record territory.
At 3 o'clock this afternoon a reading of 34.8 at the airport was more than enough to beat 1999's mark of 33.6.
A clash of hot and cool air has prompted Environment Canada to issue a severe thunderstorm watch for the city.
The city of Hamilton has issued a stage one heat advisory for today. Down the QEW in Burlington, the city will be extending hours at specific city pools as the Region of Halton issues a third stage heat response to today's sticky conditions.
Extreme heat can cause heat cramps, heat exhaustion, heat stroke and even death.
The public is advised to take precautions to reduce the risk of heat-related illnesses and to keep a lookout for the most vulnerable in your community.
