Post-tropical storm Jerry enhancing rain, flood threat in Newfoundland

Wednesday, September 25th 2019, 10:00 am - Rainfall warnings are in effect as remnants from post-tropical storm Jerry funnel north into Newfoundland.

Tuesday was a wet day across much of Atlantic Canada, with flooding rains soaking the Maritimes under a sluggish low pressure system. That heavy rain pushes into Newfoundland for Wednesday, given a tropical moisture boost by far-off post-tropical cyclone Jerry, still swirling over the Atlantic. More on how much rain to expect, and when things start to dry out, below.

The soggy start to fall flooded parts of the Maritimes on Tuesday as early morning thunderstorms rolled through the city of Charlottetown, PEI swamping some local streets ahead of the morning commute. Over 50 mm of rain fell throughout the day, with between 40-60+ mm recorded across the hardest hit areas of New Brunswick.

While Wednesday will see some lingering showers and the risk for thunderstorms, particularly for Cape Breton and near the Fundy shores, the heaviest rain will push into Newfoundland for the day. Rainfall warnings linger along the south coast of Newfoundland, where moisture streaming north from post-tropical storm Jerry will give totals a boost.

"Parts of Newfoundland can expect to receive 30-60 mm of rain through Thursday morning due to the enhanced moisture from Jerry," says Weather Network meteorologist Kelly Sonnenburg.

The now post-tropical cyclone itself is expected to curve back out into the mid-Atlantic rather than moving toward eastern Canada. On the forecast track, the centre of Jerry is expected to pass near Bermuda later Wednesday.

Another system, although with limited moisture, will then track across the region later Thursday and through early Friday. Some lingering showers are also possible this weekend with a cool and quiet pattern expected into early next week.
