dangers of flooding.

potentially dangerous in heavy rain. Do not attempt to cross flooded
roads. Find an alternate route.

...FLOOD WATCH IN EFFECT THROUGH SATURDAY EVENING...
The National Weather Service in Caribou has expanded the
* Flood Watch to include portions of East Central Maine and
Northern Maine, including the following areas, in East Central
Maine, Northern Penobscot. In Northern Maine, Southeast
Aroostook.
* Through Saturday evening
* Rainfall of around 2 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.
PRECAUTIONARY/PREPAREDNESS ACTIONS...
A Flood Watch means there is a potential for flooding based on
current forecasts.
You should monitor later forecasts and be alert for possible
Flood Warnings. Those living in areas prone to flooding should be
prepared to take action should flooding develop.

3:43 PM AST Friday 21 December 2018
Rainfall warning in effect for:
Guysborough 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 northeastern United States is forecast to track northward to pass west of the Maritimes tonight and Saturday. Light rain over southwestern Nova Scotia will become heavy at times tonight, then taper to a few showers late in the day Saturday. Total rainfall amounts of 25 to 40 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 to below freezing overnight into 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.
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 NSstorm@canada.ca or tweet reports using #NSStorm.
