10:50 AM AST Saturday 19 January 2019
Winter storm warning in effect for:

Queens County P.E.I.
Hazardous winter conditions are expected.

A strong winter storm will track across the Maritimes Sunday and Sunday night. Snow at times heavy and blowing snow ahead of this system will develop Sunday morning will change to rain at times heavy Sunday afternoon.

15 to 20 cm of snow is expected across Prince and Queens counties before it changes through ice pellets and freezing rain to rain later Sunday evening. Strong easterly winds will develop Sunday afternoon and evening gusting to 80 km/h likely giving extensive blowing snow before the precipitation changeover. The accumulated snow on the frozen ground combined with the expected rainfall and milder temperatures Sunday night could lead to treacherous road conditions well into Monday.

Rainfall warnings may be required later today to cover the Sunday night period.

Prepare for quickly changing and deteriorating travel conditions. Visibility may be suddenly reduced at times in heavy snow. Poor weather conditions may contribute to transportation delays.

Winter storm warnings are issued when multiple types of severe winter weather are expected to occur together.

Please continue to monitor alerts and forecasts issued by Environment Canada. To report severe weather, send an email to PEstorm@canada.ca or tweet reports using #PEStorm.

10:49 AM AST Saturday 19 January 2019
Rainfall warning in effect for:

Yarmouth County
Rain, heavy at times is expected. The frozen ground has a reduced ability to absorb this rainfall.

A strong winter storm will track across the Maritimes Sunday and Sunday night. Snow ahead of this system Sunday morning will change to rain at times heavy Sunday afternoon.

5 to 10 cm of snow will be followed by 25 mm of rain over southwestern Nova Scotia by late Sunday afternoon. Rain at times heavy will continue Sunday night with total amounts likely exceeding 50 mm in many areas before rain ends Monday morning. Rainfall warnings will likely be extended to the remainder of the province later today to cover the Sunday night period.

Strong southeast winds gusting up to 80 km/h are expected later Sunday afternoon, and if these gust higher Sunday night wind warnings may be required.

In addition, these winds combined with a high run of astronomical tides this weekend will give elevated water levels and heavy pounding surf along parts of the Atlantic coast during high tides Sunday night and Monday.

Localized flooding in low-lying areas is possible. Heavy downpours can cause flash floods and water pooling on roads.

Rainfall warnings are issued when significant rainfall is expected.

Strong easterly winds will develop Sunday afternoon gusting to 70 km/h likely giving extensive blowing snow before the precipitation changeover. The accumulated snow on the already frozen ground combined with the expected rainfall and milder temperatures Sunday night could lead to treacherous road conditions well into Monday.

Rainfall warnings will likely be issued later today to cover the Sunday night period.

Rapidly accumulating snow could make travel difficult over some locations. Prepare for quickly changing and deteriorating travel conditions. Visibility will be suddenly reduced to near zero at times in heavy snow and blowing snow.
