Heat Warning in effect T-storm watch called off

0

A strong thin line of severe weather pushed through eastern sections of Sault Ste. Marie early this afternoon, but environment Canada has called off the severe thunderstorm watch for the area.  They have issued a new warning due to the extreme heat and humidity.

Heat Warning in effect for:

Sault Ste. Marie – St. Joseph Island
Humidex values reaching near 39 are expected.

Heat and humidity is expected today and Wednesday with high temperatures reaching near 30 degrees. Overnight lows will be warm in the 18 to 20 degree range. There may be temporary relief from the heat due to showers or thunderstorms. The passage of a cold front on Thursday will bring an end to the heat for most areas, although some regions may still experience high temperatures near 28 degrees ahead of the front.

While heat can put everyone at risk from heat illnesses, health risks are greatest for

  • older adults;
  • infants and young children;
  • people with chronic illnesses such as breathing difficulties, heart conditions or psychiatric illnesses;
  • people who work in the heat;
  • people who exercise in the heat;
  • homeless people; and
  • people without access to air conditioning.

Frequently visit neighbours, friends and older family members, especially those who are chronically ill, to make sure that they are cool and hydrated.

Never leave people or pets in your care inside a parked vehicle or in direct sunlight.

Heat warnings are issued when very high temperature or humidity conditions are expected to pose an elevated risk of heat illnesses, such as heat stroke or heat exhaustion.

Previous warning (expired as of 3:33 pm)

Severe thunderstorm watch in effect for:

  • Sault Ste. Marie – St. Joseph Island
  • Searchmont – Montreal River Harbour – Batchawana Bay

Scattered thunderstorms are expected to track eastward across the regions this afternoon and early evening. One or two of these storms could be locally severe with damaging winds, large hail, and torrential downpours.

Be prepared for severe weather. Take cover immediately, if threatening weather approaches. Lightning kills and injures Canadians every year. Remember, when thunder roars, go indoors!

Severe thunderstorm watches are issued when atmospheric conditions are favourable for the development of thunderstorms that could produce one or more of the following: large hail, damaging winds, torrential rainfall.

The Office of the Fire Marshal and Emergency Management recommends that you take cover immediately if threatening weather approaches.
