Ponoka County, Alberta, is under a Yellow Cold Warning as arctic air combined with winds up to about 15–20 km/h pushes wind‑chill values toward −40 °C overnight on December 28 and 29. The warning covers Ponoka County, including the Town of Ponoka and the Maskwacis area, and comes during the holiday travel period when many residents are on the road.
Environment and Climate Change Canada (ECCC)’s new tiered, colour‑coded alerting system classifies “Yellow” as a lower‑tier but potentially impactful cold warning that calls for extra caution. ECCC’s Wind Chill Index warns that exposed skin can freeze in only minutes; at very cold wind‑chill values (risk increases rapidly below about −27 °C), frostbite can occur within roughly 10 to 30 minutes and can happen faster as wind‑chill values approach −40 °C.
Ponoka County Public Works is responsible for the maintenance and safety of over 1,400 miles (about 2,250 km) of highways and local roads. The county notes that road salt becomes much less effective at very low temperatures (commonly below about −18 °C), so crews rely on sand and a sand‑salt “pick” mix for traction. Drivers should slow down, leave extra space, and be alert for black ice, especially on rural routes and overpasses.
Ponoka FCSS (Family and Community Support Services) and local emergency services often coordinate warming spaces and checks for seniors and vulnerable residents during extreme cold. Residents should monitor official Town and County notices (or contact Ponoka FCSS and Ponoka County Emergency Services) to confirm whether facilities such as the Ponoka Arena Complex or the Ponoka Jubilee Library will be opened as warming centres for this event. Maskwacis Health Services and local emergency management are monitoring conditions and preparing to respond to incidents such as heating failures.
Outdoor workers are advised to take frequent warm‑up breaks, wear insulated layers with wind‑resistant outerwear and face protection, and limit time spent exposed to the wind chill. Residents should limit time outside during the coldest hours, dress in several warm layers, keep vehicles stocked with emergency kits, monitor local forecasts and road‑condition updates, and check on neighbours who may need help staying safe and warm during the extreme cold.
