A rapidly intensifying storm is set to hit parts of Atlantic Canada this weekend, bringing with it a potent mix of damaging winds, heavy snow, and the potential for coastal flooding. This storm will reach ‘weather bomb’ criteria, as the low’s minimum pressure falls 24 mb in just 24 hours.
Newfoundland looks to bear the brunt of the impacts, with special weather statements already spanning much of the island.

Residents are advised to take precautions, secure loose outdoor objects, and avoid unnecessary travel during the height of the storm.
Saturday night through Sunday:
The storm is expected to spend much of Saturday out at sea, rapidly intensifying as it approaches Newfoundland and Labrador.
Overnight, strong easterly winds will begin to pick up across the Avalon Peninsula, and heavy snow is forecast to begin falling, engulfing the island through the morning hours on Sunday.
Through the morning snow will transition to rain for the Avalon, keeping any snow accumulation relatively low for the region. Between 20-30 mm of rain is forecast to fall.
Central and western sections of Newfoundland will see the snow continue through the day, with heavy precipitation rates picking up through the afternoon hours. Snow will also fall across PEI and for the northern shores of Nova Scotia.
Milder temperatures may bring some mixing and rain to central parts of Newfoundland. As the snowfall rates decrease, coastal sections, and lower elevations, will see a transition to a rain and snow mix, keeping overall accumulations lower. Higher elevations will remain all snow, and this precipitation can linger into Monday.

A widespread 10-15 cm of snow is forecast, with as much as 20-30 cm in the harder-hit areas. The heavy snow combined with powerful winds could result in dangerous blizzard-like conditions. Drivers are urged to plan ahead and postpone any unnecessary travel plans.
100+ km/h wind gusts threaten coastal flooding, outages
The greatest impacts from this system will be the strong wind gusts.
Gusts between 80-100 km/h will move in Saturday overnight, peaking Sunday morning, and remaining gusty through the day on Sunday before easing Sunday night. Some eastern coastal sections could see gusts up to 115 km/h.
With the strong wind gusts, high waves and pounding surf are expected on Sunday for the eastern and northern shores of the island.
“These large waves can cause coastal erosion in vulnerable areas, as well as damage to infrastructure along the shoreline, especially at locations that have been prone to impacts during similar events in the past,” warns Environment and Climate Change Canada (ECCC) in the special weather statement.
Power outages are also likely due to the strong wind gusts.
