A Blustery Halloween!

Fallen leaves, Centennial Park, Moncton, 14 Oct 2019 (Dearing)

Fewer trick or treaters are expected to be spooking neighbourhoods in Greater Moncton thanks to heavy rain and strong winds.

A low pressure system could bring at least 30 mm of rain to Southeast New Brunswick over the next 24 hours.

Potentially hurricane-strength winds are expected tomorrow ahead of a cold front but temperatures will be warm reaching the high teens.

Environment Canada has issued wind warnings with gusts from 60-90 km/h and possibly up to 110 km/h in the Tantramar Marsh.

Forecasters say the wind may cause damage to buildings such as to roof shingles and windows.

The wind may not die down until early Saturday.

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.

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

Stormy Saturday in Maritimes

A line of strong thunderstorms moved across New Brunswick, western Prince Edward Island and eastern Nova Scotia on Saturday bringing heavy downpours, hail and strong winds.

Greater Moncton was under a severe thunderstorm warning for a few hours with hail about 1 cm in diameter being reported outside the city.

Heavy rain also caused flash flooding in downtown Shediac with social media posts showing vehicles making their way through water clogged streets.

Temperatures also plunged from the low 20s to the mid-teens as the storms passed.

Although the rain is needed, concert goers might disagree with the first show being staged on Magnetic Hill today in four years.

Severe weather moves across N.B.

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.

Barry weakens after making landfall

Barry has been downgraded to a tropical depression after making landfall west of New Orleans on Saturday as a Category 1 hurricane.

Although Barry did not bring devastating flooding as some forecasters had originally thought similar to Hurricane Katrina in 2005, parts of Louisiana did receive more than 400 mm of rain which swamped the Mississippi River delta.

Emergency responders rescued at least 90 residents but there were no reports of fatalities.

Remnants of Barry have been moving northward with heavy rain across the American South up to the Midwest.

Tropical Storm Barry continues churning in the northern Gulf of Mexico with sustained winds of more than 100 km/h.

The U.S. National Hurricane Center says Barry is expected to make landfall as a hurricane along the coast of Louisiana on Saturday morning.

The city of New Orleans is on alert for heavy rain (up to 500 mm) and flooding along with storm surges although no evacuations have yet been ordered.

This is the first tropical system to impact the United States in 2019.

After landfall, Barry is expected to weaken and head northward through the Mississippi Valley.

State of emergency lifted in Alberta

Days of severe weather including heavy rain, thunderstorms, hail, tornadoes and flooding led officials in western Alberta to declare a state of emergency.

However, Yellowhead County (west of Edmonton) dropped the declaration on Wednesday when floodwaters receded.

Many roads had to be closed or were made impassable after flooding and drivers were being asked to obey any barriers in place.

Residents were being warned about possible contamination of their drinking water.

Yellowhead County officials say at least 25 homes were directly impacted by floodwaters.
