A low pressure system developing off the U.S. East Coast will make a beeline for the Maritimes late Monday into Tuesday.
The track of the system is a bit uncertain right now, but it looks like it’ll cut farther inland than the last handful of winter storms we’ve seen. This inside track would also push the dividing line between rain and snow farther inland.
Precipitation will likely begin as snow for the Maritimes late Monday night and early Tuesday morning. The precipitation will quickly change over to rain for Nova Scotia on Tuesday as the low pushes warm air north over the province.
Things get trickier in New Brunswick and Prince Edward Island, where we’re likely to see both rain and snow for some areas. The precise track of the storm will determine exactly where this rain/snow divide sets up. Check back frequently for the latest updates as this divide becomes clearer.
Either way, we could see another thump of snow for areas that certainly don’t need anymore. New Brunswick and P.E.I. have anywhere from 30-60+ cm of snow on the ground right now. Moncton, N.B., had 110 cm of snow on the ground through the storm’s end on Saturday. An additional 10+ cm of snow will make it even harder to manage.
Widespread snow will reach Newfoundland overnight Tuesday into Wednesday morning.
There’s also the risk for minor ponding or flooding in some areas where rain falls on top of thick snowpacks, frozen ground, and clogged and covered storm drains. Any rainwater runoff simply won’t have anywhere to go. Streets, parking lots, and yards could see standing water where heavy rain falls on top of snow.
It’s a good idea to set aside some time to take care of any snow that needs shovelling or drains that need clearing. This next storm will add a mess on top of a mess, and proactively clearing out the last storm’s snow will help deal with whatever the next storm brings your way.
