Special Weather Statement

Issued at 22:37 Wednesday 23 May 2018

A period of near heat warning criteria will continue into Thursday.

For regions in Northern Manitoba, maximum daily temperatures reaching near 29 degrees Celsius and minimum overnight temperatures near 16 degrees Celsius will continue on Thursday.

Southern Manitoba will experience a period of high heat and humidity over the next few days as dew point temperatures climb into the upper teens on Thursday. Maximum daily temperatures and overnight minimums will remain a few degrees below heat warning criteria, however humidex values as high as 36 are possible for areas in or near the Red River Valley with values closer to 32 for the rest of southern Manitoba.

Alongside the heat, unsettled conditions will develop Thursday through Friday across much of southern Manitoba. The hot and humid conditions on Thursday will combine with a cold front pushing eastwards through western Manitoba in the afternoon, producing thunderstorms over western Manitoba that will progress eastwards into the Red River Valley on Thursday evening. There will be a moderate threat of severe thunderstorms with this system. The chance for showers or thunderstorms will continue Thursday night into Friday as an upper-level disturbance moves through the region.


Residents of and visitors to the above mentioned regions are advised to take the following precautions to protect themselves, their families and their neighbours:

- Drink plenty of water even before you feel thirsty and stay in a cool place.
- Reduce your heat risk. Schedule outdoor activities during the coolest parts of the day.
- The risks are greater for young children, pregnant women, older adults, people with chronic illnesses and people working or exercising outdoors.
- Outdoor workers should take regularly scheduled breaks in a cool place.
