Edmontonians can expect some unusual heat today as temperatures soar to 33 C — but it will feel more like 43 C with the humidity, says CBC meteorologist Stephanie Barsby.

How are you beating the heat?

Environment Canada issued a humidex advisory for most of the province, including Edmonton, advising people to stay in an air-conditioned place, seek shade when possible, drink plenty of water and limit outdoor physical activity.

At 8 a.m. the temperature in the city hit 22 C, which felt closer to 28 C.

The heat is prompting the Alberta Electric System Operator to ask Albertans to reduce their use of electricity as a number of generators are out of service for planned and unplanned maintenance, and wind generation is low.

AESO recommends you:

  • Turn off unnecessary lights and electrical appliances;
  • Minimize the use of air conditioning;
  • Close blinds, shades or drapes during the hottest part of the day;
  • Run major appliances after 7 p.m.

The AESO also says it is importing electricity from B.C. and Saskatchewan to help meet demand.

An inner-city agency is also asking for donations of bottled water, sun screen, hats and sunglasses for Edmonton's homeless population. 

Donations can be dropped off at Hope Mission Centre at 9908-106 Ave. 

Barsby warns the afternoon may see a sudden change if a cold front expected to sweep through the city  triggers severe thunderstorms.

A thunderstorm watch has already been issued for the capital region, warning of the potential development of large hail and damaging winds.

Tuesday was the second day of a what's expected to be a short heatwave. Monday's high was 28.6 C.

More than 26 daytime-high temperature records were broken across the province Monday.
