Meteorologist Ryan Snoddon says there are chances of localized flooding for Friday and Saturday. But later on Saturday, the temperatures will dip below zero and ice up for Sunday.

An incoming storm system is going to bring rain, followed by anicymess, to Nova Scotia.

The system, which is still developing across the U.S. Plains, will arrive in the province on Friday afternoon, tracking in from west to east.

While we may see a few flakes of snow and some patchy freezing rainon the northern edge of the storm on Friday morning and afternoon, this will primarily be a rainmaker for Nova Scotia, with some significant totals likely on Friday night and into Saturday.

EnvironmentCanada has issued a rainfall warningfor most of the province.

Western areas are on tap to see rainfall totals in the range of 15 to 30 millimetres, with higher totals ranging from 30 to 50 millimetres looking most likely for southern and eastern regions of the province, including the South Shore, Halifax, Truro, Pictou, Antigonish, Eastern Shore and Cape Breton regions. Local amounts could exceed 50 millimetres in some areas.

Unfortunately, the most significant rain will be falling on areas which were hit hardest by the snow earlier this month.

The southerly winds will also be howling with this system, with widespread gusts in the 50 to 60 km/h range, and stronger 70 to 80 km/h gusts possible for eastern areas on Friday night and early Saturday. As the southerly winds bumptemperatures into the mid single digits,further snow melt will follow.

Officials from Cape Breton Regional Municipality and Halifax Regional Municipalitysay flooding is a concern heading into the weekend. If you can, prepare your property ahead of time by making sure the rain and meltingsnow has an exit route.

Temperatures will remain below the freezing mark on Sunday afternoon, which means the ice will be sticking around.

As the storm departs and temperatures drop, we will also see the rain mix to a period of freezing rain, thenice pellets, and thensnow across most of the province.

While uncertainty remains, it appears near fiveto 10 cm of accumulationis a possiblefor the Northumberland Shore and into Cape Breton, with locally higher amounts possible.
