Chris could pose threat

Chris

Atlantic Canada could feel an impact from Tropical Storm Chris which has formed off the coast of the Southeastern U.S.

The Canadian Hurricane Centre says the third named storm of 2018 will move northeastward and possibly strengthen to become a hurricane by early Wednesday.

The storm could weaken as it approaches Nova Scotia by Thursday.

The CHC notes there is still uncertainty in the forecast track and intensity of this system.

Beryl is the second named storm but first hurricane of the season and has been down downgraded to a tropical storm as it heads toward Puerto Rico.

Meantime, Environment Canada issued another heat warning for New Brunswick except the Fundy coast, Prince Edward Island and northern Nova Scotia as a warm, humid air mass pushes highs into the low 30s C with humidex values up to 38 on Monday.

Thundershower as cold front sweeps Greater Moncton, 06 July 2018 (91.9 The Bend)

The passing of a cold front led to showers and thundershowers in Southeast New Brunswick today marking the end of hot, humid weather.

Environment Canada has noted Greater Moncton endured an official heat wave by definition with three straight days of at least 32°C.

The trio of record highs this week:

JULY 3rd : 31.6 C (new), 31.0 C (old record 1984)

JULY 4th : 33.4 C (new), 31.6 C (old record 2013)

JULY 5th : 34.2 C (new), 32.7 C (old record 2013)

The hotspot in New Brunswick on 05 July was a scorching 36.0 C at Miramichi and not far behind was 35.5 C at Kouchibouguac National Park.

As the heat subsides in Eastern Canada, hot weather is building in Western Canada with an impressive record high today of 39.3 C at Val Marie, Saskatchewan.

Heat wave claims lives

Temperatures across Eastern Canada from Ontario to the Maritimes continued to soar into the 30s C with humidex values above 40.

Authorities in Quebec say at least 18 people have died, all over age 50, as a warm, humid air mass lingered over the province.

Record highs have been recorded in New Brunswick with a new maximum of 31.6 C at the Greater Moncton International Airport on Tuesday (beating 31.0 C from 1984) and 33.4 C today (beating 31.4 C from 1983).

The hotspot in the province was 34.1 C at St. Stephen.

Heat warning!

Record highs could be broken in Greater Moncton over the next couple of days if forecast highs in the low to mid 30s C are reached on Tuesday and Wednesday.

Environment Canada has issued a rare heat warning for New Brunswick, mainland Nova Scotia and Prince Edward Island with cooler conditions along the coast.

A warm, humid airmass is expected to push humidex values about 40 during the day and barely falling below 18 C at night – dangerous levels for those susceptible to heat.

Forecasters believe warm, humid weather will persist until later this week when a cold front brings temperatures closer to normal for the weekend.

TWN unveils summer forecast

summer2018
Spring has sputtered in New Brunswick – it was nowhere to be found in March, finally appeared in late April and although May has had a few warm days, the month is still running slightly below normal in Greater Moncton.

So what about summer?

In its seasonal forecast, the Weather Network believes a cool June should give way to more consistent warm weather during July and August.

A humid summer is expected which may result in warmer than normal temperatures at night – overnight lows average about 12 C.

While periods of dry weather are expected, heavy showers and thunderstorms should bring rain totals to near normal for the season.

Last weekend of summer

Aboiteau Beach, Cap-Pele, NB, 17 Sept 2016 (Dearing)

I had to make at least one more trip to Aboiteau Beach in Cap-Pele yesterday before the official end of astronomical summer.

It turned out to be a beautiful day with just a few clouds, an afternoon high near 24 C and the water of the Northumberland Strait was still warm.

The beach was quiet with only a handful of sunbathers and many who arrived chose to go for a stroll along the water’s edge.

Much needed rain fell today but it was still warm and humid with a high near 20 C.

August 2016 – Warm and humid

A warm, dry trend which began in July continued in August in Southeast New Brunswick.

Although the temperature only climbed above 30 C once, there were 20 days with highs between 25 and 30 C often with high humidity and the overall monthly average was almost one degree above normal.

Rainfall was actually slightly above normal although a single rain event on 17 August delivered 35.4 mm which was more than one third the monthly total.

Tornado touches down in Maine

Severe thunderstorms moved into northwestern New Brunswick and the neighbouring State of Maine yesterday and one of those storm cells spawned a tornado.

U.S. National Weather Service officials say a tornado did touch down in Aroostook County, Maine near Caribou.

Environment Canada says funnel clouds may have been spotted in the Grand Falls area but the storm cell weakened by the time it reached New Brunswick.

Flash flooding was also reported in western parts of the province.

The severe weather came from a hot, humid air mass which has moved out of the region and has been replaced by cooler, drier air.

Heat warning for Southeast New Brunswick

For the first time this summer, Environment Canada has issued a heat warning for Greater Moncton and Southeast New Brunswick.

Humidex values between 35 and 40 degrees are being experienced inland across much of New Brunswick today.

Conditions are expected to persist this afternoon and then gradually diminish this evening as temperatures drop in the low 20’s overnight.

Another period of hot and humid weather is expected for Wednesday before subsiding at night.

Drink plenty of liquids especially water before you feel thirsty to decrease your risk of dehydration.

Heat warnings are issued when high temperatures or humidity are expected to pose an elevated risk of heat stroke or exhaustion.
