Teddy proves to be tepid

Nova Scotians breathed a sigh of relief today as Post-Tropical Storm Teddy packed a bigger bark than a bite.

The Canadian Hurricane Centre says the expansive storm made landfall near Ecum Secum, along the eastern shore of Nova Scotia, around 8 a.m. ADT with heavy rain and winds up to 105 km/h.

Large destructive waves were hazardous along the Atlantic coast and authorities urged storm watchers to stay home for their own safety.

Teddy quickly moved over Nova Scotia into the Gulf of St. Lawrence on its way to western Newfoundland.

A rainfall warning was issued for Southeast New Brunswick with Greater Moncton getting about 30 mm of rain and a peak wind gust of 80 km/h.

Hurricane Sally came ashore near the Alabama/Florida border early Wednesday with torrential rain and damaging winds up to 170 km/h.

The U.S. National Hurricane Center says the Category 2 storm quickly weakened to a tropical depression but 300 to 600 mm of rain fell in some areas causing massive flooding.

Sally was the 18th named storm of the 2020 Atlantic hurricane season with several more systems still churning.

The remnants of Sally will brush the Maritimes on Friday but only about 10 mm of rain is expected.

Belize cleans up after Nana

The fifth hurricane of the 2020 Atlantic season struck Belize on Thursday as a Category 1 storm after causing flooding in Honduras.

Forecasters say Nana made landfall in a sparsely populated area about 80 km south of Belize City with sustained winds of 120 km/h and later dissipated near the Mexico-Guatemala border.

Belize authorities say about 4,000 residents were moved to shelters but no injuries or deaths were reported.

Damage appeared to be minimal with the worst impacts on banana plantations.

Powerful Laura pummels U.S. Gulf Coast

Hurricane destruction in Lake Charles, LA, USA, 27 Aug 2020 (Twitter)

Hurricane Laura left a path of destruction and claimed numerous lives, becoming one of the strongest hurricanes to ever strike the United States.

A Category 4 hurricane with drenching rain and winds up to 241 km/h, Laura made landfall in Louisiana near the Texas border early Thursday and even spawned tornadoes before being downgraded to a tropical storm.

Laura destroyed entire neighbourhoods, knocking out electricity to millions but U.S. forecasters noted the hurricane was not as forceful as first thought.

Given the low lying, swampy landscape of the region, ‘unsurvivable’ storm surges had been predicted.

Prior to striking the U.S. Gulf Coast, Laura took at least two dozen lives in Haiti and the Dominican Republic.

Sweltering heat grips the West

The western half of North America is baking with the thermometer climbing above 50°C in California’s Death Valley.

The World Meteorological Organization is verifying Sunday’s unofficial high of 54.4°C (134°F) and it could become the world’s hottest temperature recorded since 1931.

Severe thunderstorms have produced lightning and strong winds in the western U.S. – increasing the threat of wildfires.

Extreme heat is also impacting interior British Columbia where the thermometer peaked at 41.2°C in Lytton while several locations in Alberta and Saskatchewan climbed to 38°C.

Another tornado touchdown in Manitoba

Severe thunderstorms in southwestern Manitoba produced heavy rain, quarter-sized hail, strong wind gusts – and a tornado.

Environment Canada confirmed the tornado on Friday and assigned it an EF-0 rating with winds ranging from 90-150 km/h.

The twister touched down in Alexander, just west of Brandon, shortly before 6pm Thursday, causing some minor damage but no reports of anyone injured.

Six days ago to the west, an EF-2 tornado hit the Virden area where two people were killed and another injured when their vehicles flipped over.

Winds of up to 190 km/h snapped trees, downed power lines and damaged farms.

‘Extremely active’ hurricane season

Conditions in the Atlantic basin are favourable for fueling storms according to a mid-season update on the 2020 hurricane season.

The U.S. National Oceanic and Atmospheric Administration calls this an “extremely active” season and has increased the odds for above normal activity and the number of named storms since its May forecast.

Historically by early August, only two named storms form on average but we already have a record-setting nine named storms in the books.

An average Atlantic season produces 12 named storms including six hurricanes of which three become major hurricanes (Category 3, 4, or 5).

Isaias inundates Quebec

Post-tropical storm Isaias carved a path through the centre of Quebec on Tuesday bringing strong winds and significant amounts of rain.

Although rainfall amounts generally ranged from 35 to 70 mm, some areas recorded more than 100 mm – over a month’s worth of precipitation.

Fallen branches and trees led to power outages throughout the province with a maximum wind gust of 91 km/h at Ile d’Orleans near Quebec City.

The remnants of Isaias merged with a low pressure system over Labrador and the Canadian Hurricane Centre posted its last update on Wednesday night.

Rainfall amounts (in mm) as of 11am EDT 05 August:

  • Le Massif de Charlevoix 120 mm
  • Trois-Rivieres 100 mm
  • Shawinigan 83 mm
  • Drummondville 79 mm
  • Quebec City (Sainte-Foy) 46 mm
  • Montreal (downtown) 45 mm

Isaias moves quickly up U.S. East Coast

Isaias made landfall late Monday as a Category 1 hurricane near the border of North and South Carolina and was later downgraded to a tropical storm.

Heavy rain and strong gusty winds brought flooding and storm surges to some U.S. East Coast cities.

New York City recorded wind gusts at more than 110 km/h which were the strongest since Superstorm Sandy in 2012.

Forecasters say Isaias is moving quickly at about 65 km/h which has spawned tornadoes which have proven deadly.

The Canadian Hurricane Centre says Isaias will enter Quebec tonight as a post-tropical system with up to 60 mm of rain expected and wind gusts up to 70 km/h.

New Brunswick was originally in the storm’s path but the storm kept shifting to the west and mostly gusty winds are expected Wednesday.
