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.
The parade of hurricanes in the Atlantic continues with Maria making landfall late tonight over the eastern Caribbean island nation of Dominica as a powerful category 5 storm packing sustained winds of 260 km/h.
The U.S. National Hurricane Center is outlying a path for Maria which is eerily similar to the recent Hurricane Irma with the U.S and British Virgin Islands and Puerto Rico expected to be impacted on Wednesday.
Maria will be accompanied by a dangerous storm surge and between 300-500 mm (12-20 inches) of rain to some of the islands causing life-threatening flash floods and mudslides.
Meantime, Hurricane Jose is still churning northward as a category 1 storm with heavy surf and rip currents along the U.S East Coast from North Carolina to Massachusetts.
Canadian forecasters say the remnants of Jose have already brought high humidity to the Maritimes and will give Nova Scotia persistent moisture and cloud cover as well as rough surf along the Atlantic coast.
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.
The U.S. National Oceanic and Atmospheric Administration is predicting hurricane activity in the North Atlantic Ocean in 2017 is likely to be above normal (45 percent) or near-normal (35 percent).
The Canadian Hurricane Centre says it responds to 4 or 5 tropical cyclone events each year on average, with 1 or 2 of those affecting Canadian land and another 2 or 3 threatening offshore waters.
Hurricanes are typically a greater concern in Canadian waters later in the season but the Canadian Hurricane Centre monitors the Atlantic Ocean year‑round for any tropical or tropical‑like cyclone that could pose a threat to Canada or its waters.
Hurricane Matthew passes over Les Cayes, Haiti, 04 Oct 2016 (Reuters)
Hundreds of thousands of Florida residents along its east coast from Fort Lauderdale to Cape Canaveral have been told to evacuate in advance of Hurricane Matthew.
The powerful category 3 storm is churning through the Bahamas after a brush with eastern Cuba and has maximum sustained winds at 185 km/h.
Floods and mudslides from the storm in Haiti and the Dominican Republic have claimed more than 800 lives.
The U.S National Hurricane Center believes by early Friday, Matthew will track parallel to the Atlantic coast from Florida to the Carolinas and is not certain yet if the storm will hit land.
The last time a major hurricane made landfall in the United States was Wilma in 2005 which was blamed for 35 deaths and billions of dollars in damage.
The Canadian Hurricane Centre doesn’t believe Matthew will have any significant impact on Atlantic Canada.
Hurricane Kate has formed north of Bermuda but the Canadian Hurricane Centre says the storm is not expected to impact Atlantic Canada.
The fourth hurricane of the 2015 Atlantic season was centred 420 kilometres north of Bermuda early today and moving northeast at 65 km/h.
The maximum sustained winds were 120 km/h.
Forecasters are monitoring Kate and an unrelated system south of Cape Cod that could bring some rain to Nova Scotia and Newfoundland.
As of this morning, Tropical Storm Claudette is about 450 km southeast of Yarmouth, Nova Scotia with maximum sustained winds of 74 km/h and is moving northeast toward Newfoundland.
The Canadian Hurricane Centre says Claudette is expected to weaken with the storm likely becoming post-tropical by tonight.
The track shows the storm will likely arrive onshore near the Burin Peninsula of Newfoundland.
UPDATE – On 15 July at 9 a.m., the Canadian Hurricane Centre issued its last statement when Post-Tropical Storm Claudette weakened once it moved onshore along the southeastern coast of Newfoundland.

Hurricane Gonzalo passed about 50 km south of Cape Race, Newfoundland as a Category 1 storm near dawn this morning.
The Canadian Hurricane Centre noted strong winds gusting up to 100 km/h were reported at Cape Race with higher gusts in the Grand Banks which created 5-12 metre waves along the Atlantic coast.
Flash flooding was reported across the Avalon Peninsula with 50-60 mm of rain falling in St. John’s over just a few hours.
The fast moving Gonzalo, which passed directly over Bermuda on Friday as a Category 4 storm, is now a post-tropical system heading toward the United Kingdom.
Hurricane Cristobal continues to churn in the Atlantic tonight, about 450 km east-southeast of Cape Hatteras and racing northeastward toward the Grand Banks.
The Canadian Hurricane Centre says Cristobal will likely merge with a cold front moving southward over Atlantic Canada.
Forecasters say the result will be periods of heavy rain, gusty winds and fall-like temperatures for the Maritimes and Newfoundland by Friday.

Forecasters say the season’s first hurricane is expected to bring significant rain and wind to the Maritimes on Saturday.
Arthur became a hurricane today with maximum sustained winds of about 120 kilometres per hour.
Forecasters say a trough of low pressure will move eastward from the Great Lakes and guide the storm toward the Maritimes.
The Canadian Hurricane Centre says the storm’s projected track has been moved slightly to the west with significant rain and wind for the Maritimes but it’s too early to make rainfall and wind speed predictions.
