After striking land in Louisiana and later in Mississippi early today, Hurricane Nate has weakened to a tropical storm as it heads inland over the Southeastern United States.

Sustained winds of 140 km/h had dropped to 70 km/h after landfall but storm surges caused flooding along the Gulf coast and more than 200 mm of rain could fall in some areas.

Nate originated in the southwestern Caribbean Sea and claimed more than 30 lives in Central America before moving northward.

The Canadian Hurricane Centre has issued a tropical cyclone statement for Southern Ontario with remnants of the storm expected to bring up to 40 mm of rain on Thanksgiving Day.

September 2017 – Summer continues

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).

Meteorological Summer in Greater Moncton

If you were looking for great summer weather in the province, Environment Canada says Greater Moncton and Southeast New Brunswick was the place to find it this year. 

The average temperature for meteorological summer – June, July and August – was 18.1 C which is 0.7 degrees above normal. 

The weather office says humidity was often low, overnight lows were comfortable but 8 days hit 30 C or higher compared to a typical 4 to 5. 

The downside was a lack of precipitation with 155 mm of rain recorded which is 40 percent less than the summer average of 268 mm. 

Harvey finally downgraded

Tropical Storm Harvey has been downgraded to a tropical depression but not before creating a new weather record in the United States.

Climatologists say Harvey is the worst rainfall event ever with 1318 mm (51.88 inches) of rain recorded at Cedar Bayou, Texas beating the previous mark of 1219 mm (48 inches) in Medina, Texas from Tropical Storm Amelia in 1978.

Thousands of residents could still be stranded and an estimated 40,000 homes have been destroyed by the storm in the Houston area.

Heavy rain is now moving over Louisiana, Mississippi, Arkansas and Tennessee with some areas expecting more than 200 mm.

Catastrophic flooding in Houston

More than 3,500 residents of Houston have been rescued since Tropical Storm Harvey began pounding southeastern Texas with more than 750 mm of rain and counting.

Tens of thousands displaced from their homes are being housed at evacuation centres which are now overcapacity forcing many to sleep in chairs or on the floor.

Officials began releasing water from two Houston reservoirs on Monday in order to prevent uncontrollable flooding in the downtown area.

Houston’s two main airports have been closed since their runways are completely underwater.

The Texas Gulf Coast is a key centre of the American oil and gas industry with some of the largest refineries in the United States halting operations.

Harvey hammers Houston

Harvey may have been downgraded to a tropical storm as it moved inland over Texas but the U.S. National Weather Service stated “this event is unprecedented and all impacts are unknown and beyond anything experienced.”

Forecasters say the Houston metropolitan area could receive more than 1000 mm of rain from the storm over the next few days which has claimed at least five lives. 

By early today, more than 600 mm had fallen in America’s fourth largest city overwhelming lakes and rivers forcing thousands of residents scrambling into boats or onto rooftops to safety.

Tornado warnings have been lifted but a flash flood warning remains in place for much of southeastern Texas.

Hurricane Harvey threatens Texas

The worst storm to hit Texas in 20 years is expected to reach the state’s Gulf of Mexico coastline by early Saturday. 

The U.S. National Weather Service warned Harvey could bring a potentially devastating storm surge, up to 900 mm of rain and powerful winds to portions of the state. 

Harvey will be the first Category 3 hurricane to make landfall in the United States since Hurricane Wilma in 2004.

A voluntary evacuation order has been issued for the coastal city of Corpus Christi with a population of more than 500,000 people.

Gert churns up the Atlantic

Hurricane Gert is not going to pose any threat to land in Atlantic Canada according to the Canadian Hurricane Centre but it will be felt in the sea.

The swell from the Category 1 storm will move into the Atlantic coast of Nova Scotia on Wednesday (16 August) and will persist into Thursday.

The swell will produce waves breaking up to three metres along parts of the coast and rip currents are likely.

Forecasters say Gert will not produce any rainfall for the region but the tropical moisture could feed into another low pressure system arriving later this week.

Much needed rain arrives

A thunderstorm rolled through Greater Moncton on Friday afternoon and it was a welcome sight when two periods of downpours brought much needed rain.

A fire ban had been in place across Southern New Brunswick but more rain today lowered the fire hazard and burning is now allowed from 8pm to 8am.

The last significant rainfall in Greater Moncton was 8.2 mm on 21 July and prior to that it was 21.2 mm on 24 June.

Agriculture Canada has declared that much of Prince Edward Island is experiencing a drought with little rain since early June.

July 2017 – Warm and dry

As the month of July progressed in Southeast New Brunswick, lawns turned brown and forests became extremely dry as temperatures soared and little rain fell.

Greater Moncton only received one-third of its normal monthly rainfall and 15 days had no precipitation at all.

The heat was steady throughout July with 20 days reaching 25 C or higher and four days climbing to 30 C or more.

A brief cool down near month end lowered daytime highs to the low 20s Celsius and brought a chilly overnight low of 6.9 C.
