Mid-December Rainstorm Update One

3:53 PM AST Thursday 20 December 2018

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 developing low pressure system over the Gulf of Mexico is forecast to track northwards to pass west of the 

Maritimes on Friday night and Saturday. Light rain will begin over southwestern Nova Scotia Friday 

morning and becoming heavy at times Friday night, then taper to a few showers Saturday afternoon. 

Rainfall accumulations are forecast to reach 15 to 25 mm by early Saturday morning, with additional 

amounts expected during the day on Saturday.

Strong southerly winds accompanying the system will bring unseasonably warm temperatures to the region 

Friday night and Saturday, with daytime highs expected to reach the low to mid teens 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.

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.
