Extra rain? Let’s hope not.
Up to now, it’s trying like Canada will get a cross from Hurricane Helene, which upgraded from tropical storm standing earlier as we speak and is forecast to make landfall in Florida on Thursday as a Class 3 or 4 storm.
Present monitoring exhibits the storm remaining at hurricane energy because it enters Alabama, after which backing off to a post-tropical storm because it enters Tennessee and Kentucky. It’s then anticipated to maneuver to the west and inland earlier than really fizzling out over the weekend.
The U.S. National Hurricane Center is predicting the storm may attain Class 3 (sustained winds of 178 km/hr to 208 km/hr) by the point it makes landfall on Sept. 26. Which means its impression on the U.S. Gulf Coast, together with excessive winds, storm surge and heavy rain and flooding, might be main. And residual results might be felt far from the storm’s centre.
“[Our] meteorologists anticipate this to be a extremely impactful storm,” AccuWeather Chief Meteorologist Jon Porter told U.S. media outlets. “This might be the storm that the 2024 hurricane season is remembered for.”

Tropical Storm Helene shall be strengthened by “supportive circumstances and unusually heat sea floor temperatures,” says Anna Neely, managing director and head of disaster R&D at London-based Howden Re in a press release.
“In the very best case, a giant bend landfall may lead to losses mirroring Hurricane Idalia’s US$3 billion to US$5 billion; however a major swing in both route – both towards the peninsula or panhandle might produce losses that exceed US$10 billion to US$15 billion, just like Hurricanes Michael or Irma,” Neely provides.
“Whereas precise impacts are nonetheless unsure, the important thing issue is whether or not Helene will strike a low- or high-population space, with billions probably in danger.”
Canada in its sights?
Up to now, the Canadian Hurricane Centre has not issued any warnings related to Helene.
Plus, the Climate Community factors to an interplay of two low stress techniques that create what’s known as the Fujiwhara impact as a motive Canada might get a cross. The Fujiwhara impact causes one cyclone to merge into one other and on this case would push Helene onto the westward monitor forecast by each the Canadian and U.S. hurricane centres.
“In Helene’s case, the atmospheric trough south of the border would stop the remnants of the storm from persevering with on to Jap Canada. As an alternative, they’re prone to flip westward earlier than finishing their life cycle, with the higher low absorbing Helene into it,” the Weather Network notes.
“There are nonetheless some laptop fashions that pull the moisture additional north into Canada, so it’ll be one thing to look at and see if the Fujiwhara impact verifies.”
Past the storm
That final level’s necessary since, as climate occasions thus far this season have proven, it’s not all the time the hurricanes and tropical storms themselves that wreak havoc in Canada. It’s the residual rainfall and winds from the storms’ remnants.
Regardless of Canadians being hit by mere remnants of Hurricanes Debby and Beryl in July and August, summer season 2024 nonetheless ranks because the most-destructive season within the nation’s historical past for insured losses, as reported by Insurance coverage Bureau of Canada (IBC), citing preliminary estimates from Disaster Indices and Quantification Inc. (CatIQ).
4 catastrophic climate occasions this summer season induced a combined total of over $7 billion in insured losses, IBC notes. Within the face of that, IBC reiterated its name for an entire of society strategy to fixing the issue.
“Insurers at the moment are paying out extra in claims for a single occasion than the $1.9 billion that the federal authorities has allotted to local weather adaptation over the previous decade,” says Craig Stewart, IBC’s vice chairman for local weather change and federal points. “Canada must prepare for the subsequent catastrophe.”
