10:21 PM AST Friday 22 December 2017
Rainfall warning in effect for:

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

A developing low pressure system approaching from the Great Lakes will continue to spread light snow

across western portions of the province tonight and transition into rain at times heavy for mainland Nova

Scotia by Saturday afternoon.

Rainfall totals up to 30 millimetres are possible, especially along the Atlantic coastline and Cape Breton with

rain tapering off 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 ec.weatheraspc.ec@canada.ca or tweet reports using #NSStorm.

10:05 PM AST Friday 22 December 2017
Special weather statement in effect for:

Cumberland County North and Cobequid Pass
A developing low pressure system approaching from the Great Lakes will continue to spread a period of light

snow across western portions of the province tonight and transition into rain for mainland Nova Scotia by

tomorrow afternoon. Rainfall warnings have been issued for counties along the Atlantic coast but there

remains a possibility that rainfall amounts could still exceeding warning criteria of 25 millimetres elsewhere.

A second low pressure system is forecast to develop off Cape Hatteras on Sunday and intensify as it moves

northeastward, impacting Nova Scotia on Christmas day. Snow ahead of the storm will spread across the

province on Christmas day starting early in the morning over southwestern areas and reaching Cape Breton

by late morning. As the storm intensifies on Christmas day winds will also strengthen and combined with

the snow give reduced visibilities in blowing snow.

At this point it is too early to give exact amounts and the areas most likely to be affected, but model

guidance suggests warning criteria of 15 centimetres or more could be reached or exceeded.

In addition, this intense low will produce large waves and storm surge, which may give higher than normal

water levels and rough and pounding surf for the north facing shorelines of Cape Breton Island and

extending west to Pictou County Monday night.

Environment Canada will continue to monitor the development of this storm and provide updates as new

information becomes available.

Please continue to monitor alerts and forecasts issued by Environment Canada. To report severe weather,

send an email to ec.weatheraspc.ec@canada.ca or tweet reports using #NSStorm.

9:50 PM AST Friday 22 December 2017
Special weather statement in effect for:

Queens County P.E.I.
A developing low pressure system approaching from the Great Lakes will spread a period of light snow into

the province beginning Saturday afternoon and transition into rain Saturday evening, before ending Sunday

morning. There may be significant rain with this system, possibly exceeding rainfall warning criteria of 25

millimetres.

A second low pressure system is forecast to develop off Cape Hatteras on Sunday and intensify as it moves

northeastward impacting Prince Edward Island on Christmas day. Snow ahead of the storm will spread

across the province on Christmas day starting in the morning and persisting into the evening. As the storm

intensifies winds will also strengthen and combined with the snow give reduced visibilities in blowing snow

Christmas night.

It still remains too early to give an indication of snowfall amounts or the areas most likely to be affected, but

model guidance shows a possibility of exceeding warning criteria of 15 centimetres.

In addition, this intense low will produce large waves and storm surge, which may give higher than normal

water levels and rough and pounding surf for the north facing shorelines of the island Monday night.

Environment Canada will continue to monitor the development of this storm and provide updates as new

information becomes available.

Please continue to monitor alerts and forecasts issued by Environment Canada. To report severe weather,

9:45 PM AST Friday 22 December 2017
Snowfall warning in effect for:

Campbellton and eastern half of Restigouche County
western half of Restigouche County
Snowfall, with total amounts of 15 to 20 cm is expected.

A low pressure system approaching from the Great Lakes will move through southern New Brunswick

Saturday night and then east of the province on Sunday. It will bring snow to northern New Brunswick

Saturday afternoon. The snow will be mixed at times with ice pellets in the evening and it should end by

Sunday morning. Current forecast guidance suggests snowfall amounts of up to 20 centimetres.

Rapidly accumulating snow will make travel difficult. Visibility may be suddenly reduced at times in heavy

snow.

Snowfall warnings are issued when significant snowfall is expected.

Please continue to monitor alerts and forecasts issued by Environment Canada. To report severe weather,

send an email to ec.weatheraspc.ec@canada.ca or tweet reports using #NBStorm.

 9:44 PM AST Friday 22 December 2017
Freezing rain warning in effect for:

Fredericton and Southern York County
Freezing rain is expected or occurring.

A low pressure system approaching from the Great Lakes today will move through southern New Brunswick

Saturday night and then east of the province on Sunday. It will bring freezing rain and ice pellets in the

western parts of the province beginning Saturday afternoon, which will spread north and east in the

evening. This freezing precipitation should end by Sunday morning. Current forecast guidance suggests

amounts of 5 to 10 millimetres resulting in significant ice accretion especially over central regions where the

freezing rain will persist for a longer time.

Surfaces such as highways, roads, walkways and parking lots may become icy and slippery. Poor weather

conditions may contribute to transportation delays. Utility outages may occur.

Freezing rain warnings are issued when rain falling in sub-zero temperatures creates ice build-up and icy

surfaces.

Please continue to monitor alerts and forecasts issued by Environment Canada. To report severe weather,

send an email to ec.weatheraspc.ec@canada.ca or tweet reports using #NBStorm.

9:43 PM AST Friday 22 December 2017
Special weather statement in effect for:

Saint John and County
A developing low pressure system approaching from the Great Lakes will spread a mixture of snow, ice

pellets, freezing rain and rain across New Brunswick Saturday. Significant amounts of precipitation is

expected and various winter warnings have been issued for all counties expect Charlotte and Saint John

where milder temperatures will produce rain.

We are also monitoring the future development of another major storm that will likely impact southern parts

of the province on Christmas Day. At this point it looks like a snowfall event with the highest amounts in the

south beginning Christmas morning. It is too early to give exact amounts and the areas under highest

threat, but model guidance suggest warning criteria of 15 centimetres or more. There may also be gusty

winds and reduced visibility in blowing snow.

In addition, this intense low will produce large waves and storm surge over the Gulf of St. Lawrence, which

may give higher than normal water levels and rough and pounding surf along the Acadian coast Monday

afternoon.

Environment Canada will continue to monitor the development of this storm, and will provide updates as

new information becomes available.

Please continue to monitor alerts and forecasts issued by Environment Canada. To report severe weather,
