Monday, June 16, 2025<\/strong>, conditions are becoming highly conducive to the development of severe thunderstorms<\/strong> across parts of western Alberta<\/strong>, with potentially dangerous impacts expected through the evening.<\/p>\n An unstable system is intensifying along the foothills of the Rocky Mountains<\/strong>, creating an atmosphere rich in moisture and energy. Areas including Banff, Calgary, and Edmonton<\/strong>, extending north toward the northeastern corner of British Columbia<\/strong>, will be exposed to severe thunderstorms<\/strong> starting Monday afternoon.<\/p>\n Thunderstorm cells<\/strong>, fuelled by a warm, humid airmass and a sharp pressure gradient, could escalate into locally violent storms<\/strong>. Main threats include wind gusts exceeding 90 km\/h<\/strong>, large hailstones<\/strong>, and torrential downpours<\/strong> over a short period.<\/p>\n While Calgary and Edmonton<\/strong> are currently in a zone forecasted for non-severe activity<\/strong>, instability may quickly expand<\/strong>, especially between late afternoon and the evening hours<\/strong>. Residents are urged to closely follow local weather alerts<\/strong> to avoid being caught off guard.<\/p>\n Although large hail and strong winds<\/strong> remain the primary threats, there is also a marginal risk for tornadoes<\/strong> to develop across a stretch of unstable air<\/strong> over southwestern Alberta. In the event of a tornado warning<\/strong>, it is crucial to seek shelter immediately in an interior room, away from windows<\/strong>.<\/p>\n People across affected regions are advised to stay vigilant throughout Monday evening<\/strong>. The most intense storms<\/strong> are expected to initiate between 2:00 p.m. and 9:00 p.m. local time<\/strong>, though storm activity may persist well into the night<\/strong>, particularly across rural and elevated areas in the northwest<\/strong>.<\/p>\n Today\u2019s temperatures range from 22 to 28\u202f\u00b0C (72\u201382\u202f\u00b0F)<\/strong> with moderate humidity levels, which are ideal conditions for the formation of tall cumulonimbus clouds<\/strong> capable of producing damaging weather.<\/p>\n <\/p>\n Keep a close eye on local advisories<\/strong> and be prepared for potential power outages or travel disruptions<\/strong>, especially in the foothills and northwestern Alberta<\/strong>.<\/p>\n","protected":false},"excerpt":{"rendered":" Monday, June 16, 2025, conditions are becoming highly conducive to the development of severe thunderstorms across parts of western Alberta, with potentially dangerous impacts expected through the evening.
