Back to SearchToday, Southwestern Public Health issued its first heat advisory of the year which also happens to be the first local heat advisory issued during the COVID-19 pandemic.
A heat warning or extended heat warning is issued when prolonged exposure to outdoor conditions could prove dangerous to public health. Today’s heat warning is based on forecasted temperatures around 30°C this afternoon, with a similar forecast for Wednesday in the City of St. Thomas, Elgin County and Oxford County. Humidex values in the mid to upper thirties are also expected.
“A heat warning in the context of a pandemic causes some additional complexities for some members of the community – particularly those who may typically rely on libraries and other public facilities as cooling stations. As we know, those locations are closed due to the pandemic, so municipalities are working quickly to find safe and appropriate alternatives,” says Amy Pavletic, Program Manager for Environmental Health at Southwestern Public Health.
The health unit is working with municipalities and community agencies to update the list of publicly available cooling stations available during the pandemic. In the meantime, community members are asked to check in, via phone or video, with vulnerable family, friends and neighbours, especially older adults who live on their own.
Quick facts (and/or Background)
Public Health will 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 31°C and overnight temperatures are at or above 20°C for two days or the Humidex is forecasted to be at least 40°C for two days.
- Extended Heat Warning – When forecast temperatures are expected to be at least 31°C and overnight temperatures are above 20°C for three or more days or Humidex is at least 40°C for three or more days.
- During a heat event, members of the public should:
- Limit time in the sun when the UV Index (ultraviolet ray strength) is most intense, between 11am - 4pm.
- Take cool showers or baths. Electric fans improve air circulation but will not prevent heat-related illness. During extreme temperature conditions, stay indoors and if possible, stay in an air-conditioned place.
- Be aware of signs and symptoms of heat cramps, heat exhaustion, and heat stroke. Follow first aid procedures promptly.
- When in the sun, wear a wide-brimmed hat (or with back flap), UV protective sunglasses, loose-fitting long shirts and pants. Seek shade when outside, especially during midday.
- Apply Sunscreen with SPF 30 (or higher), 20-30 minutes before going outside to ensure absorption. Reapply every 2-3 hours.
