HARS has three alert levels. The levels are based on the Humidex value.
*Humidex is a temperature index that describes how hot the weather actually feels to a person, by adding the effect of heat and humidity.
The Regional Public Health Offices monitor Humidex* values established by Environment Canada to determine when it is necessary to issue a Heat Alert. The Regional Public Health Offices advise the public that conditions exist that could result in negative health effects.
The heat alert will be issued:
- on the Government of New Brunswick main web page,
- the Department of Health twitter account @NBHealth
When a Heat Alert (Level 1) is issued, certain vulnerable persons may be affected. The main cause of illness and death during a heat wave is the aggravation of pre-existing respiratory and cardiovascular diseases.
When a High Heat Alert (Level 2) is called, everyone is at increased risk of heat stress and heat stroke under the conditions.
- People living alone without air conditioning are at high risk especially if the heat wave lasts many days.
- Check regularly on your neighbours and relatives to make sure they are not in danger
- Organizers of sport and recreational activities should build in regular water breaks and rest or consider rescheduling activities.
During an Extreme Heat Alert (Level 3) everyone is at high risk for heat related illnesses and heat stroke.
- People living alone without air conditioning are at extreme risk.
- Check regularly on your neighbours and relatives to make sure they are not in danger.
- Organizers of sport and recreational activities should reschedule activities.
