* Rainfall of 1.5 to 2.5 inches with locally higher amounts will
  fall across the region through Saturday morning. These amounts
  could lead to localized flooding of urban and low-lying areas
  and significant ponding of water on roads. In addition, warm
  temperatures will cause snow melt which combined with the
  heavy rain could lead to moving ice in rivers, possibly
  leading to ice jams.

10:53 AM AST Friday 21 December 2018
Rainfall warning in effect for:

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

A developing low pressure system over the eastern United States is forecast to track northward to pass west of the Maritimes today and tonight before moving northward into Quebec on Saturday.

Rain and strong southerly winds associated with this system have begun over western New Brunswick and will continue to spread across the remainder of the province throughout the day. In parts of

central and northwestern New Brunswick, precipitation will continue to fall as freezing rain today before transitioning to rain as temperatures rise.

At this time, rainfall amounts of up to 30 mm are forecast for central and northwestern New Brunswick by Saturday afternoon. Higher amounts approaching 60 mm are expected in southwestern New

Brunswick.
Additionally, as heaviest rains move in to the region, southerly wind gusts up to 80 km/h are expected, especially over exposed coastal areas and over the higher terrain of southern New Brunswick tonight

and into early Saturday morning.

Furthermore, the southerly winds will bring unseasonably warm temperatures to the province tonight and Saturday, with daytime highs expected to reach the mid teens for parts of New Brunswick on

Saturday. The rain and melting snow may cause minor flooding in some areas. Cool northwesterly winds behind the system will quickly drop temperatures to below freezing by Sunday morning.

Heavy downpours can cause flash floods and water pooling on roads.

Rainfall warnings are issued when significant rainfall is expected.

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

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

A strong low pressure system over the eastern United States is forecast to track northwards west of the Maritimes today and Saturday. Light rain will begin over southwestern Nova Scotia today and

becoming heavy at times this evening, then taper to a few showers late in the day Saturday. Total rainfall amounts of 30 to 50 mm are expected with this system with possible higher amounts in areas of

heaviest rain.

Strong southerly winds accompanying the system will bring unseasonably warm temperatures to the region tonight and Saturday, with daytime highs expected to reach into the double digits on Saturday.

The rain and melting snow may cause minor flooding in some areas. Cool northwesterly winds behind the system will quickly drop temperatures near freezing during the day Sunday.

In addition, large waves and higher than normal water levels are likely along parts of the Atlantic coast on Saturday.

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