U.S. forecasters have unveiled their projections for the 2020 Atlantic hurricane season and it promises to be a busy one with 13 to 19 named storms and 6 to 10 becoming hurricanes.
The U.S. National Oceanic and Atmospheric Administration (NOAA) believes several factors are at play this year including above average sea surface temperatures, weaker tropical trade winds and an expected La Nina climate pattern.
Although the season doesn’t officially begin until 01 June, there has already been one named storm – Arthur – which had peak wind gusts of 95 km/h and neared the Southeastern U.S. before moving out to sea without striking land.
The Canadian Hurricane Centre will also be keeping an eye on storms which enter northern waters.
Last September, Hurricane Dorian made landfall near Halifax and caused destruction across Nova Scotia, Southeast New Brunswick and Prince Edward Island.

Back-to-back low pressure systems brought a messy mix of precipitation to much of the Maritimes over the weekend.
Rain began falling Saturday with a near record warm high of 11 C in Greater Moncton which melted any snow on the ground.
However, the next system brought colder temperatures and more than ten hours of ice pellets (sleet) in Southeast New Brunswick sometimes mixed with snow and freezing rain.
About 15 cm of ice pellets and snow accumulated Sunday which forecasters say is quite rare and it was certainly heavy to move.

Just days into the new year, a low pressure system has brought mostly snow to Atlantic Canada especially near the ocean.
For most of Nova Scotia, it was winter’s first major snowfall with up to 15 cm at Halifax Stanfield Airport and nearly 40 cm in Sydney.
The storm grazed Greater Moncton with only 3 cm of snow.
After leaving the Maritimes, the system brought 42 cm snow to St. John’s, Newfoundland and 30 cm to the Burin Peninsula with a peak wind gust of 106 km/h in Bonavista.
Meantime, forecasters say another low pressure system is coming midweek.

The latest low pressure to invade the Maritimes is bringing heavy rain and strong winds to Southern New Brunswick and Northern Nova Scotia.
Environment Canada has issued a rainfall warning with up to 70 mm possible especially along the Fundy coast and strong winds gusting up to 90 km/h.
Meteorologists say that much rain is a lot for frozen ground to absorb and along with an existing snowpack could create localized flooding.
After a few days with below freezing temperatures, the small amount of snow in Greater Moncton has been taken away by the rain and a mild high of 12°C.
The forecast is calling for much colder air behind this system with some snow likely on Wednesday.

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.

The remnants of Tropical Storm Olga were felt across Southern Ontario on the weekend with rainy and windy conditions.
Environment Canada says between 30 and 60 mm of rain fell across the region including the Greater Toronto Area.
Wind gusts were up to 80 km/h in some locations with a peak of 104 km/h recorded at Port Colborne on Lake Erie.
Olga formed in the Gulf of Mexico several days ago and made landfall in Louisiana before quickly churning northward toward the Great Lakes.
Forecasters are calling for more wet weather and cooler conditions by Halloween.

Cooler, fresher air moved into the Maritimes this weekend following the passage of a cold front.
Saturday’s daytime high of 18.1°C in Greater Moncton was the chilliest daily maximum since 01 July.
Sunday’s morning low was 5.2°C which was the coolest since 25 June.
Forecasters say the fall-like weather won’t last long with more summer-like conditions expected by midweek.
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.

A good old fashioned January cold snap continues in New Brunswick with well below normal temperatures since last weekend.
Wind chill values have dropped to -30 giving the risk of frostbite on exposed skin.
After a frosty -21.4°C in Greater Moncton earlier this week, forecasters say a further tumble to -23°C is likely before a potent winter storm arrives on Sunday.
Environment Canada is tracking a system moving across the U.S. which is expected to bring at least 30 cm of snow, 50 mm of rain, a period of freezing rain and strong winds to the Maritimes.

A major winter storm brought heavy snow and mixed precipitation from the American Midwest to the mid-Atlantic states over the weekend.
The snow began falling in Kansas and Missouri with some areas getting almost 50 cm.
The storm knocked out power, disrupted air travel and created slippery highways with numerous collisions including an Illinois crash which killed a police officer.
Freezing rain led to a build-up of ice on surfaces in North Carolina and Virginia.
Between 15 and 30 cm of snow fell over the Washington, DC area – its heaviest snowfall in three years – which closed schools and federal government offices on Monday.
Forecasters say melting during the day would create hazardous black ice after sunset as temperatures fell back below freezing.
The storm system has moved out into the Atlantic but will brush Cape Breton Island and eastern Newfoundland on Tuesday.
