This final week of November remains active across much of Atlantic Canada, with the latest system pushing into Newfoundland for Tuesday, bringing strong winds, heavy rain and snow. Around 15 cm of snow had already fallen in parts of New Brunswick by the morning hours, with the rain winding down in the already flood-vulnerable areas of eastern Nova Scotia. Flooding will still be a concern in Newfoundland, as an additional 20-40 mm is still to come in areas hit hard by last week's event. On top of the heavy precipitation, winds will be blustery once again for parts of the region, with upwards of 100 km/h gusts possible for parts of Newfoundland. More on what's left of the potent system and a look ahead to the ongoing storm parade, below.

TUESDAY: LINGERING WIND, SNOW, RAIN EFFECTS AS POTENT SYSTEM PUSHES EAST
Weather warnings are continuing to drop across Atlantic Canada, as the strong East Coast low makes its way out of much of the Maritimes and brings more impacts to Newfoundland and Labrador through Tuesday.
Moderate rain will continue across Newfoundland, as the low pressure system continues to track east. Additional rainfall totals of 20-40 mm are anticipated, so localized flooding remains a concern. Heavy snow and the risk for freezing rain is forecast for Labrador through the day before gradually easing through the overnight.
Sea-effect snow will also pick up in Newfoundland in the afternoon hours Tuesday, as the low exits the province.
Strong southerly winds ahead of a cold front however, will bring wind gusts of 70-120 km/h to the Avalon and exposed coastal areas. Behind this system, blustery west winds will continue into Wednesday and will produce sea-effect snow squalls across western Newfoundland and western Cape Breton.
LOOK AHEAD: UNCERTAIN TRACK FOR NEXT POTENTIAL SYSTEMS
Additional storm systems are anticipated to move into the region Thursday-Friday, but models are in disagreement on the outcome. One scenario has two lows pushing across the region, while the other has just one storm – but a larger and stronger system.
Regardless of the ultimate outcome, unsettled weather and windy conditions are likely with rain for a large part of the region, but a swath of significant snow, as well.
Another significant system is possible this weekend with a more southerly storm track, with the potential for significant snow for more populated areas. Another potent storm is possible early or mid-next week.
