September turned out to be a continuation of summer in Southeast New Brunswick right up until month end.

Daytime highs in Greater Moncton climbed above 25 C on ten days and a monthly maximum of 31.1 C turned out to be the warmest of 2017 set in early fall (26 Sept).

Although hurricanes never directly affected the province, meteorologists say much of the warmth last month came from tropical air pushed northward from these storms.

Rainfall was exactly normal but almost all of the precipitation fell during a single rain event spread over two days (6-7 Sept).

Having a heat wave in late September is unusual for Southeast New Brunswick but even more so is that the highest temperature of 2017 has occurred in early autumn.

The thermometer soared to 31.1 C yesterday (26 September) at the Greater Moncton International Airport which breaks the previous maximum of 29.6 C from 2007 and records date back to 1881.

The previous high for the year had been 30.6 C recorded on 04 August.

At least 10 other New Brunswick communities set new record highs yesterday including Fredericton at 32.8 C, Woodstock at 32.3 C and Bouctouche at 31.8 C.

Environment Canada says temperatures will return to more seasonable values by the weekend with highs between 16 and 18 C.

Early fall heat

This may have been the first weekend of autumn in Southeast New Brunswick but it felt more like the first weekend of summer instead.

Greater Moncton climbed to 27.7 C yesterday (23 September) while today (24 September) it hit 27.9 C and the normal high for late September is 17 C.

High pressure and a northerly jet stream has pushed heat across Eastern Canada with highs in the low 30s C in many parts of Ontario and Southern Quebec.

A heat warning was in place as Toronto Pearson Airport reached a record-breaking 33.1 C yesterday and 33.6 C today.

Autumn officially arrives

The autumnal equinox arrived in New Brunswick at 5:02pm ADT.

Days and nights are now roughly equal in length and the sun is directly overhead at the equator and will head southward.

The leaves in Greater Moncton are starting to show hints of fall colours and experts say a dry summer could mean the display will not be as brilliant.

The Weather Network is forecasting a warmer and wetter autumn season compared to normal.

Snow in Edmonton!

The northernmost city in North America with over one million residents had 5 cm of snow today. 

Edmonton had a winter-like day during the final days of summer when a cold rain turned white making highways slippery. 

Alberta weather can be highly variable given that on 07 September, the provincial capital climbed to 32.8 C – the warmest temperature so far this year. 

Environment Canada says the cold and snow will be short-lived with sunshine and daytime highs climbing to 16 C by the weekend. 

Maria becomes a menace

MariaThe parade of hurricanes in the Atlantic continues with Maria making landfall late tonight over the eastern Caribbean island nation of Dominica as a powerful category 5 storm packing sustained winds of 260 km/h.

The U.S. National Hurricane Center is outlying a path for Maria which is eerily similar to the recent Hurricane Irma with the U.S and British Virgin Islands and Puerto Rico expected to be impacted on Wednesday.

Maria will be accompanied by a dangerous storm surge and between 300-500 mm (12-20 inches) of rain to some of the islands causing life-threatening flash floods and mudslides.

Meantime, Hurricane Jose is still churning northward as a category 1 storm with heavy surf and rip currents along the U.S East Coast from North Carolina to Massachusetts.

Canadian forecasters say the remnants of Jose have already brought high humidity to the Maritimes and will give Nova Scotia persistent moisture and cloud cover as well as rough surf along the Atlantic coast.

September usually doesn’t disappoint in Southeast New Brunswick when it comes to warm weather and so far this month is no exception.

Environment Canada reports on 14 September, the thermometer climbed to 27.8 C in Greater Moncton which ties the record high from 2003.

St. Stephen was the hot spot in the province and all of Canada with a high of 29.2 C which eclipsed the old record from 1903.

As we approach the first day of autumn on 22 September, temperatures in Greater Moncton can still climb into the 30s Celsius with a record high of 32.8 C in 1965.

Irma swamps Florida

Irma was downgraded from a hurricane to a tropical storm today after slamming Florida with destructive wind, heavy rain, flash flooding, high storm surges and even tornadoes.

Irma, one of the most powerful hurricanes ever recorded in the Atlantic Ocean, made landfall over the Florida Keys on Sunday before coming ashore near Naples and then heading up the state’s west coast.

Miami was not in the storm’s direct path but was still battered by strong winds which swayed high rise buildings, brought down three construction cranes and downtown streets were swamped.

In northeast Florida, Jacksonville had historic flooding after the swollen St. Johns River spilled its banks and officials said dangerous conditions were expected for several days.

Prior to arriving in the United States, Irma claimed 10 lives in Cuba according to state media after battering Havana and tourist resorts such as Varadero and Cayo Coco where the international airport was destroyed.

Hurricane Irma has barreled through the Caribbean as a Category 5 storm claiming more than 20 lives and destroying more than 90 percent of the buildings on the islands of Barbuda, St. Martin/St. Maarten and St. Barts.

Irma is heading for Florida where officials say it could be the strongest storm ever and evacuation orders have led to massive lineups at gas stations as residents flee northward.

Following a similar path, Hurricane Jose is a Category 4 storm which could hit the already battered islands of Antigua and Barbuda.

Hurricane Katia is a Category 2 storm in the Gulf of Mexico which will make landfall along Mexico’s east coast bringing heavy rain and a storm surge before dissipating quickly over the rugged Sierra Madre mountains.

Forecasters say three simultaneous hurricanes is quite rare and the last time was in 2010 with Hurricanes Igor, Julia and Karl.
