About weather alerts

Oxford County Public Health issues heat and cold advisories to warn residents about weather conditions that may impact their health. Cold and heat advisories are posted to the Alerts & advisories web page, Facebook, and on Twitter.

Environment Canada also issues text bulletins and weather alerts to warn people about extreme weather in their area.

Cold weather alerts

A cold weather alert is issued when current or anticipated weather conditions are at or below -15 degrees Celsius or -20 with wind chill, or when there are extreme weather conditions, such as a blizzard or ice storm.

Remember, hypothermia is an emergency health condition that occurs when the body temperature drops too low, making it difficult to move and think clearly. Warning signs are shivering, exhaustion, confusion, fumbling hands, memory loss, slurred speech and drowsiness. Infants may have red, cold skin and very low energy. If you suspect hypothermia, get medical attention immediately by calling 911 or going to the nearest emergency department.

2016 Cold weather alerts

Health Canada fact sheet: Extreme cold

Heat advisories and warnings

A new procedure is in place for 2016 in declaring heat events that could prove dangerous to public health with prolonged exposure to the conditions.

Environment and Climate Change Canada's meteorological services will directly notify Oxford County Public Health when there is an impending heat event in our area.

A warning about the conditions will be posted on the Oxford County Public Health website, in the Oxford County Newsroom, and will be sent out to local media, child care providers and other community partners.

Public Health will then issue a Heat Warning or Extended Heat Warning based on the duration and intensity of the expected conditions:

  • Heat Warning - When forecast temperatures are expected to be at least 31oC and overnight temperatures are at or above 20oC for two days or the Humidex is forcasted to be at least 40oC for two days.
  • Extended Heat Warning - When forecast temperatures are expected to be at least 31oC and overnight temperatures are above 20oC for three or more days or Humidex is at least 40oC for three or more days.

During an extended heat event, cooling centres like libraries, arenas and other public buildings may be opened to the public for relief from the heat. The cooling centres typically include air conditioning, seating and water and are managed by each city, town or township. Click on the image below for a list of cooling centre locations and hours.

Stay safe in the heat

Public Health reminds people that the combination of high heat and high humidity can be dangerous. Anyone who experiences physical distress because of extreme temperatures should seek medical attention immediately either by calling 911 or going to the nearest emergency department.
