Environment Canada is warning of another "multi-day heat event" that will bring temperatures in the low-to-mid 30s to Ottawa-Gatineau and the wider region starting Sunday.

The weather agency issued warnings Saturday afternoon for the national capital, as well as a large swath of eastern Ontario stretching from Prince Edward County north to Pembroke and east to Cornwall and the Quebec border.

In Ottawa, daytime highs will range from 30 C to 34 C over the next few days, although the humidity could make it feel more like 42, Environment Canada said.

Overnight lows will range from 19 C to 23 C, they said.

It will likely be the hottest on Monday, Environment Canada said, and the extremely warm weather could stretch into Wednesday in some places.

An earlier heat wave in late June saw similarly brutal temperatures across the region, with communities like Ottawa, Gatineau, Kemptville and Trenton all setting daily records, according to preliminary Environment Canada data.

CBC’s Nkele Martin spoke with experts about dangerous symptoms to look out for and what types of activities are safe when the mercury starts to rise.

Health Canada recommends staying cool and staying hydrated when extreme heat hits.

That can mean everything from drinking lots of water and rescheduling outdoor activities for cooler times, to preparing meals that don't require ovens and keeping track of nearby air-conditioned spaces.

Watch for signs of heat exhaustion — like a headache, dizziness or a rapid heartbeat — and get to a cool place where you can drink water.

Heat stroke, which includes symptoms like confusion and very hot or red skin, is a medical emergency. Anyone who feels they have heat stroke should call 911.
