Heat warning issued for Montreal

A few isolated thunderstorms in the Montreal area on Saturday brought some relief from the hot, humid conditions in Montreal — but that won't last.

Environment Canada has issued a heat warning for the Montreal area for the rest of the weekend. On Sunday, the forecast high for Montreal is expected to reach 30 degrees, with Humidex levels in the low 40s.

The weather office issues heat warnings when heat and humidity levels can pose an elevated risk of heat illnesses, such as heat stroke or exhaustion.

Meanwhile, organizers of the Osheaga festival are taking steps to make sure festivalgoers stay as cool as possible.

In a statement released on Saturday, organizers say they've added more free water fountains, more sprinklers and hoses to spray festivalgoers.

They're also making sure fans in the front rows have better access to water, and are also adding more shading areas.

The festival is expected to close on Sunday night, with a performance by the British band Florence and the Machine. 

This hot, humid weather is expected to last through at least Monday in Montreal.
