Confidence is highest from Sunday afternoon through Monday evening, when the individual models line up best on timing and on a colder snow-level drop. They converge on snow reaching all elevations across Alberta and staying below base at Kicking Horse and Big White.
The Mount Hotham Airport station recorded a temperature of 0.9°C on Thursday, with a feels-like temperature of -5.1°C and strong south-southwest winds gusting over 30 km/h. The resort's weather station also recorded the coldest reading in the state, at -2.2°C at a nearby monitoring point.
Australians are struggling through one of the most brutal heatwaves and hottest summers on record. Day after day, temperatures into the high 30s are turning homes into ovens, workplaces into hazards, and everyday tasks into endurance tests. All of us are feeling it. But spare a thought for the millions of renters trying to survive this heat in homes that were never designed to cope with it.
Australia's east coast is being smashed by summer storms as residents are told to evacuate. An emergency warning was in place for Sydney's northern beaches on Sunday morning, with residents at Narrabeen Lagoon and surrounds told to leave. More than a dozen people have been rescued across Sydney, with cars submerged and homes flooded. At Great Mackerel Beach, in the northern beaches, a landslide damaged numerous homes with at least one woman injured.
A focused Sunday-through-Tuesday storm brings the only meaningful snowfall window, with the best accumulation in Canterbury and lighter spillover elsewhere. Guidance supports a regional high-elevation refresh around 20 cm-30 cm at the top end, while most other fields stay in a modest 1 cm-6 cm range. Expect mostly dense to moderate snow quality during the core burst.
The Environment Agency (EA) has issued 85 warnings for England, meaning flooding is expected, mainly concentrated in the south-west and Midlands. A further 245 flood alerts are in place, meaning flooding is possible, from North Yorkshire to Cornwall and from the Welsh borders to Norfolk. Natural Resources Wales has another 11 flood alerts in place while Scotland has one flood warning and five flood alerts.
WeatherNew Zealand's Southern Alps see a small, wet early-week storm that peaks on Tuesday, with Mt Hutt and Mount Dobson leading totals. Snow levels start high Monday night near 6,200-6,600 feet, then drop into the 4,700-5,000 feet range on Tuesday as temperatures settle near freezing, improving the odds of snow reaching lower mountain elevations. Snow quality stays on the heavy side with SLRs mostly around 6-7:1, so expect dense, moisture-rich snow rather than light powder, and moderate southeast winds add some exposed-ridge bite.
