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.

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.

Fall preview for Atlantic Canada

After what seemed like a short summer – it didn’t get started until early July in Southeast New Brunswick – The Weather Network has unveiled its 2019 fall forecast.

  • Much of Atlantic Canada should see above-average rainfall due to a few systems that tap into tropical moisture and bring excessive totals.
  • Above normal temperatures are expected to dominate across the southern Maritimes, while typical fall temperatures are expected elsewhere.

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.

Hurricane Dorian landfall expected near Halifax

Dorian update

Emergency measures organizations in the Maritimes have been preparing for Hurricane Dorian which is approaching southwestern Nova Scotia with maximum winds of 148 km/h (as of 12pm ADT).

The Canadian Hurricane Centre expects Dorian will make landfall near Halifax on Saturday evening as a Category 1 hurricane.

Residents who live along the Atlantic coast, such as Peggys Cove for example, are being urged to evacuate and move inland.

Long lines were reported at stores and gas stations on Friday as residents scrambled to stock up on food and other supplies.

Hurricane warnings and tropical storm warnings have been issued for all of Nova Scotia including Cape Breton Island, Prince Edward Island and southeast New Brunswick.

Strong winds gusting up to 120 km/h are in the forecast, rainfall amounts could exceed 100 mm and large waves and storm surges are likely along coastlines.

As of 2pm ADT, about 75,000 customers were without electricity in Nova Scotia with some trees toppled over along the province’s south shore.

Greater Moncton and Southeast New Brunswick (warnings as of 2pm ADT)

  • Tropical Storm Warning – heavy rain, strong winds, storm surges along the coast
  • Wind Warning – gusts up to 90 km/h which could cause damage, uproot trees
  • Rainfall Warning – 50 to 100 mm rain (a month’s worth) could cause flooding

Dorian likely to track near Nova Scotia

Dorian path

As slow-moving Hurricane Dorian continues churning parallel to the coastline of the Southeastern United States, the Canadian Hurricane Centre is getting a better sense of how the storm will impact Atlantic Canada this weekend.

Forecasters believe Dorian could be a Category 1 storm when it arrives on Saturday and follow a path to the east of mainland Nova Scotia.

Rainfall will be heavy to the west of the track which includes Southern New Brunswick with about 50 mm possible and perhaps as much as 100 mm for parts of Nova Scotia.

Hurricane-force winds with large waves and pounding surf are possible along the Atlantic coast near the track before the storm heads to Newfoundland on Sunday.

The U.S. National Hurricane Center says Dorian is now moving toward the coast of the Carolinas with strong winds, storm surges and up to 300 mm of rain.

Erin drenches Maritimes

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
  • Kentville 115
  • Summerside 67
  • Fredericton 56
  • Moncton 50
  • Halifax (city) 48

August snow in northern BC!

Ft Nelson snow

Residents of northern British Columbia were shocked to wake up to snow this morning – an estimated 50 cm in some areas.

Environment Canada says cold Arctic air combined with moisture from the Pacific was responsible for the winter-like conditions in late summer.

Fort Nelson received a mix of rain and snow while higher elevations of 1,000 metres or more saw mainly snow.

Historical data shows measurable snow is likely in Fort Nelson in every month except July.

By contrast on Monday, Kamloops in the Okanagan Valley – about 1300 km south – reached a daytime high of 31°C.
