Puerto Rico managed to avoid a direct hit from Hurricane Dorian but the Bahamas may not be as lucky with officials calling it a “life-threatening” storm.

The U.S. National Hurricane Center says the Category 4 major hurricane has sustained winds of 240 km/h and could bring a powerful storm surge with large, powerful waves and up to 600 mm of rain to the northwestern Bahamas.

Forecasters say Dorian is expected to turn northward before it reaches Florida but storm impacts will be felt along the Southeastern United States coastline.

Florida has declared a state of emergency with tropical storm warnings in effect and some residents are being ordered to evacuate in case of coastal flooding.

Erin drenches Maritimes

Post-tropical depression Erin interacted with an incoming low pressure system to produce lots of rain in the Maritimes.

Environment Canada says the heaviest amounts were recorded in northern Nova Scotia and the Annapolis Valley – Parrsboro and Greenwood each had more rain from this storm than all of July and August combined.

Some roads were damaged and even washed out by surface runoff or flooding.

Erin’s direct path along Nova Scotia’s south shore produced wind gusts up to 80 km/h.

The storm brought tropical air with a high of 23°C in Greater Moncton on Friday but a humidex of 32.

Rainfall totals (mm):

  • Parrsboro 162
  • Greenwood 127
  • Kentville 115
  • Summerside 67
  • Fredericton 56
  • Moncton 50
  • Halifax (city) 48

Erin heading to Maritimes

Erin
Tropical cyclone activity is heating up and the latest named storm is tracking northeastward toward the Maritimes.

Tropical Storm Erin is currently off the coast of the Southeastern United States and is expected to be downgraded to a post-tropical system before reaching the Atlantic coast of Nova Scotia by early Friday.

The Canadian Hurricane Centre says the heaviest rain, possibly 50 to 100 mm, will fall north and west of Erin’s track while the strongest winds will be to the east up to 90 km/h.

Meantime, Hurricane Dorian is churning in the Caribbean and forecasters say it will hit eastern Puerto Rico late Wednesday with heavy rain potentially causing flooding and landslides.

Brazil’s Amazon is burning

Forest fires are raging in the Amazon rainforest and international pressure has forced the Brazilian government to bring in the military to help.

Official figures show the number of fires has surged by 84 percent this year in Brazil with over 78,000 reported – more than half in the Amazon region.

Many blazes have been human caused and environmentalists blame the jump on farmers clearing land for pasture.

Smoke from the fires has drifted into major cities like São Paulo where the afternoon sky recently became so dark it looked like night.

A state of emergency was declared in Manaus where many residents are suffering from respiratory problems.

August snow in northern BC!

Ft Nelson snow

Residents of northern British Columbia were shocked to wake up to snow this morning – an estimated 50 cm in some areas.

Environment Canada says cold Arctic air combined with moisture from the Pacific was responsible for the winter-like conditions in late summer.

Fort Nelson received a mix of rain and snow while higher elevations of 1,000 metres or more saw mainly snow.

Historical data shows measurable snow is likely in Fort Nelson in every month except July.

By contrast on Monday, Kamloops in the Okanagan Valley – about 1300 km south – reached a daytime high of 31°C.

Quiet forest fire season in N.B.

A wet, cold spring and a dry, humid July have led to one of the quietest forest fire seasons in recent memory in New Brunswick.

Statistics show 152 fires for the season to date which compares to 206 fires over the past ten years.

Last year was also much busier with 242 fires recorded by the middle of August.

Provincial wildfire officials say although July was warmer than normal, high humidity levels helped prevent fires from starting and from spreading.

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.

How does July 2019 compare?

Julys in Moncton
Greater Moncton recorded an average temperature of 20.0°C last month but how did it compare to previous July’s going back to 2012?

According to the 30-year average (1981-2010) at the Greater Moncton International Airport, the July normal is 18.8°C.

Of the past eight July’s, only one was actually below average in 2015 while the others were above normal.

The historic warmest July was in 2018 while 2014 was not too far behind.
