An intense low pressure system is heading to the Maritimes.
Heavy rain will start during the morning hours in Greater Moncton and strong winds will develop by midday.
Environment Canada says rainfall amounts could reach 50 mm while easterly wind gusts of 70 km/h or higher are likely.
Some trees may be at risk of falling after being weakened by Hurricane Dorian last month.
Many leaves will undoubtedly drop which could plug storm drains causing localized flooding.

Autumn began just a few days ago but it already looks and feels like winter in parts of British Columbia, Alberta and Saskatchewan.
A strong low pressure system prompted snowfall and winter storm warnings as up to 100 cm of snow fell across southern Alberta.
Gusty winds behind the system created blowing and drifting snow making highway travel treacherous.
Many early season snowfall records have been broken.
Snowfall amounts (in cm) as of 1pm MDT, 30 September:
- Calgary 32
- Claresholm 40-45
- Lethbridge 50-60
- Taber 60
- Cardston area 70-90
- Waterton Park 95

Dorian damage in Halifax’s West End, 08 Sept 2019 (NS Power)
Hurricane Dorian has left a path of destruction across the Maritime Provinces despite being downgraded as it crossed the region.
The Canadian Hurricane Centre says Dorian was an intense post-tropical storm as it made landfall at 7:15pm ADT Saturday in Sambro, 25 km southwest of Halifax.
Dorian brought destructive winds, flooding rains and powerful storm surges to much of Nova Scotia, southern New Brunswick and Prince Edward Island.
A construction crane collapsed and century old trees toppled onto homes, businesses, vehicles and streets in Halifax.
Public works staff are scrambling to clean up the mess and power crews are trying to restore electricity to the tens of thousands without it.

Post-tropical depression Erin interacted with an incoming low pressure system to produce lots of rain in the Maritimes.
Environment Canada says the heaviest amounts were recorded in northern Nova Scotia and the Annapolis Valley – Parrsboro and Greenwood each had more rain from this storm than all of July and August combined.
Some roads were damaged and even washed out by surface runoff or flooding.
Erin’s direct path along Nova Scotia’s south shore produced wind gusts up to 80 km/h.
The storm brought tropical air with a high of 23°C in Greater Moncton on Friday but a humidex of 32.
Rainfall totals (mm):
- Parrsboro 162
- Greenwood 127

Dark clouds northwest of Moncton, 31 July 2019 (Dearing)
A line of severe thunderstorms slid through New Brunswick tonight producing heavy rain, hail and strong, gusty winds up to 100 km/h.
Small funnel clouds were noticed but no reports of tornadoes.
Environment Canada issued watches and warnings for many parts of the province including Greater Moncton.
The ridge of storm clouds passed to the northwest of the city and not a single drop of rain fell but it did drop temperatures enough to end the heat warning.
Bomb cyclone centre in U.S. Midwest, 14 Mar 2019 (earth.nullschool.net)
A so-called bomb cyclone brought blizzard conditions to Colorado and now heavy rain, flooding and even tornadoes to the U.S. Midwest.
The weather bomb occurs when there is a rapid drop in atmospheric pressure over a 24 hour period.
Further north, the storm is dumping snow across Minnesota as it moves into northwestern Ontario.
Severe thunderstorm watches have been posted for Southern Ontario with strong winds expected along with heavy rain.
New Brunswick will the effects this weekend with significant rainfall and gusty winds in the forecast.
Open areas like West Main Street were prone to drifting snow, 26 Feb 2019 (Dearing)
Strong winds created blowing and drifting snow across New Brunswick today which caused whiteout conditions on highways.
RCMP say a multi-vehicle pileup on Highway 11 near Cocagne late this morning involved 15 vehicles in a series of collisions.
Visibility was poor in whiteouts near the Cocagne Bridge.
The highway was closed as emergency responders cleared the wreckage and waited for the weather to improve.
Winds gusted as high as 85 km/h in Greater Moncton which created a bitterly cold wind chill giving a risk of frostbite on exposed skin.
Aftermath of ice storm in NE Moncton, 08 Feb 2019 (Dearing)
Southern New Brunswick received several hours of freezing rain Friday morning – enough to make highways and other surfaces extremely icy.
Schools were cancelled, many businesses delayed opening until midday, pedestrians were forced to walk like penguins and even salt trucks slid off the road in Nova Scotia.
Ice coated my own steps to the point where I had to slide down them and crawl to my car which was a few metres away.
Greater Moncton only received about 10 mm of rain but the water eventually froze when a cold front followed the ice storm and temperatures plummeted by early Saturday.
Winds were also strong behind the system gusting at times up to 90 km/h.
Environment Canada is forecasting colder than normal weather but mostly clear skies over the next few days.

A strong winter storm will track across the Maritimes Sunday bringing a mixed bsg of precipitation to Southeast New Brunswick.
Snow at times heavy will begin in the morning changing to ice pellets and freezing rain by noon and eventually to rain later in the afternoon.
Greater Moncton is expecting about 20 cm snow, 20 mm of rain and possibly several hours of ice accumulation.
Strong winds will develop giving reduced visibility in blowing snow with gusts reaching 80 km/h along the Fundy coast.
Conditions may not improve until Monday afternoon as the storm moves eastward.
About 12 cm snow fell in Moncton on New Year’s Day, 01 Jan 2019 (Dearing)
New Year’s Eve celebrations were just getting started in Greater Moncton when snow flurries began falling from the latest low pressure system moving through the region.
By the time the snow stopped late this afternoon about 12 cm had fallen in Southeast New Brunswick with higher amounts toward the north and east.
Rain had been expected but the temperature never climbed above freezing as forecast.
In the wake of the storm, strong northwesterly winds will usher in frigid air creating windchill values near minus 30 and a risk of frostbite.
