Strong fall storm coming

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.

Manitoba declares state of emergency

The Manitoba government declared a state of emergency on Saturday after a powerful storm dumped heavy rain, freezing rain, snow and wind to southern portions of the province this week.

Amid the early winter blast, Manitoba Hydro is trying to restore electricity to thousands of residents after numerous trees and branches – many still covered in leaves – fell onto power lines with winds gusting up to 100 km/h.

The storm was so bad it forced the temporary closure of the Trans Canada Highway from Winnipeg to the Saskatchewan border.

Southern Manitoba got blasted after a Colorado Low moved in from the United States where it brought dramatic temperature drops and heavy snow to the Great Plains states.

The next concern for local emergency measures officials will be flooding as the snow melts given the rising temperatures forecasted over the next few days.

Snowfall totals as of 1pm CDT on Saturday, October 12th:

  • Carberry  74 cm
  • Morden  64 cm
  • Winnipeg  34 cm
  • Dauphin  30 cm
  • Brandon  29 cm

September 2019 – Dorian’s fury

Hurricane Dorian defined September for Southeast New Brunswick, Prince Edward Island and Nova Scotia.

Although downgraded before making landfall near Halifax, Dorian was still a very destructive storm.

Powerful winds toppled century-old trees onto power lines, a month’s worth of rain drenched the region in hours and a vicious storm surge tossed boats around like toys.

If it hadn’t been for Dorian, the month would have been quite dry in Greater Moncton.

September also lacked heat with slightly below normal temperatures thanks to chilly nights and cool daytime highs which often struggled to reach 20°C.

Storm cleanup continues

No one expected Dorian to batter Southeast New Brunswick with such intensity.

Hurricane-force winds and a powerful storm surge along the Northumberland Strait wrecked wharves and fishing boats, tossed yachts like toys at a marina, flooded campgrounds and destroyed camper trailers.

For the first time in its history, Parlee Beach has been closed to the public after boardwalks and ramps were damaged posing safety risks for visitors.

The cleanup at Murray Beach may take weeks where dozens of fallen trees closed the campground, kitchen shelters were flattened and the beach itself was heavily eroded.

Torrential rain washed out sections of some roads including in Salisbury where a car plunged into a gaping hole.

Public works crews in Greater Moncton have been clearing away downed trees and branches which were responsible for most power outages.

Five days after Dorian, thousands are still without electricity in Nova Scotia where century old trees toppled onto homes and vehicles.

Many city parks remain closed in Halifax due to debris and efforts begin to dismantle a construction crane which collapsed during the strong winds.

Dorian packs powerful punch

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.

Dorian devastates Bahamas

A number of fatalities have been reported as slow-moving Hurricane Dorian wreaks havoc in the Bahamas with more 13,000 homes severely damaged.

The strongest storm to ever hit the island nation – a Category 5 with sustained winds of 320 km/h – made landfall in the Abaco Islands with drenching rain and massive storm surges creating devastating flooding.

Downgraded to a Category 4 storm but still very dangerous, hurricane watches and warnings have been posted along the southeastern United States coastline from Florida to South Carolina.

In current projections, the U.S. National Hurricane Center suggests Dorian could reach the Maritime Provinces by Saturday.

Bahamas braces for Dorian

Puerto Rico managed to avoid a direct hit from Hurricane Dorian but the Bahamas may not be as lucky with officials calling it a “life-threatening” storm.

The U.S. National Hurricane Center says the Category 4 major hurricane has sustained winds of 240 km/h and could bring a powerful storm surge with large, powerful waves and up to 600 mm of rain to the northwestern Bahamas.

Forecasters say Dorian is expected to turn northward before it reaches Florida but storm impacts will be felt along the Southeastern United States coastline.

Florida has declared a state of emergency with tropical storm warnings in effect and some residents are being ordered to evacuate in case of coastal flooding.

Severe weather moves across N.B.

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.

Hurricane season begins

2018 hurricanes

Today marks the beginning of the 2019 hurricane season which will run until the end of November.

For a record fifth consecutive year, storm activity began before the 01 June official start date when Subtropical Storm Andrea formed on 20 May.

The U.S. National Oceanic and Atmospheric Administration (NOAA) is forecasting a near normal season with 9–15 named systems, 4–8 hurricanes, and 2–4 major hurricanes.

The Canadian Hurricane Centre begins issuing statements when a storm is within three days of entering a response zone covering Eastern Canada and adjacent waters.

Weather bomb crosses the continent

Bomb cyclone

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.
