Hurricane Katrina pushed the sea 10 kilometres inland in some communities. This wall of water turned a destructive cyclone into a generational tragedy along the northern Gulf Coast. More than 1,300 people died as Katrina’s fierce winds and unprecedented storm surge changed both coastlines and communities. A confluence of factors contributed to Katrina’s legacy as one of the worst storms in living memory. But it all started with the hurricane’s unique storm surge.

Katrina was a classic peak-season hurricaneA weak disturbance that blew off the coast of Africa on Aug. 11 would grow into one of the most destructive hurricanes in modern history.

What are Santa Ana winds, and why are they so dangerous?

What are Santa Ana winds, and why do they fuel California wildfires? Santa Ana winds can down trees, trigger power outages and even damage buildings. They're also notorious for fanning some of the most destructive wildfires in Southern California history. What are Santa Ana winds? These winds form when an area of high pressure builds over the Great Basin, a region in the Intermountain West that includes Nevada and parts of other neighboring states. When this high forms, it creates a sharp pressure difference between the interior and the coast. Air then rushes downhill to the sea in an attempt to create balance. But there's an issue: California's mountain ranges get in the way.(MORE: The Pineapple Express is a firehose, and El Niño just turned it up)These hot, dry winds continue to speed up as they descend mountains. Any sparks can quickly become raging wildfires. This air is forced to squeeze through narrower mountain passes and canyons. One of these mountain ranges is the Santa Ana Mountains in Orange County, which is how these winds got their name in the first place.

Rare and destructive tornado strikes Italian towns in Sicily

A rare tornado struck western Sicily on Friday, damaging homes and sending several people to the hospital. The storm reportedly began as a waterspout before coming ashore and tracking several kilometres inland, hitting the towns of Petrosino and Marsala, southwest of Palermo. DON’T MISS: Tornado, funnel cloud, waterspout, landspout, gustnado: what’s the difference? A video posted to Facebook appeared to show numerous vehicles overturned. Reuters reported on Friday that several people sustained injuries in the storm. Friday’s incident was an example of a tornadic waterspout, which is a full-fledged tornado that forms over water. These dangerous storms can track inland, as was the case in Sicily on Friday. Most of Italy’s organized tornado activity is centred within the Po Valley in the northern part of the country. Powerful supercell thunderstorms are known to hit cities between Milan and Venice with very large hail, destructive winds, and occasional tornadoes. Historical records hold several dozen reports of tornadoes in Sicily since the 19th century. A particularly damaging and deadly tornado struck the city of Catania on Oct. 7, 1884.

Beware the 'I' hurricanes, even during a super El Niño

Hurricane Isaias appears to be the most impactful storm of the 2026 Atlantic hurricane season dominated by a super El Niño. So far this century, storms beginning with "I" have often been the most damaging. (MORE: Latest forecast | tracking maps)Eleven "I" hurricanes retiredOver the past 25 years, 11 other "I" hurricanes have had their names retired by the World Meteorological Organization. By retired, we mean no future Atlantic Basin storm will use that name again. The name is retired when a particular tropical storm or hurricane is so deadly and/or damaging that future use might be considered insensitive or confusing. When that happens, a new name is chosen by a WMO committee that will be used every six years going forward. Isaias replaced Ike when that notorious 2008 hurricane name was retired.

Hurricane Juan was one of the East Coast’s most destructive storms

Hurricane Juan cemented its place in history during the early morning hours on Sept. 29, 2003, when it swept across Atlantic Canada with ferocious winds. The first hurricane to directly strike Halifax since the late 1800s, Juan caused hundreds of millions of dollars in damage and killed several people throughout the region. DON’T MISS: Hurricane Fiona, two years later: Could it happen again? Juan quickly developed and strengthenedA tropical disturbance around 550 km southeast of Bermuda served as the seed that would eventually grow into Hurricane Juan. The disturbance encountered a complex setup influenced by the remnants of Hurricane Isabel that hit the U. S. Mid-Atlantic one week earlier. The system quickly advanced from a tropical depression the morning of Sept. 24 into a full-fledged hurricane just 48 hours later. A ridge of high pressure to Juan’s northeast quickly steered the storm directly toward Nova Scotia. This speedy forward motion didn’t allow any time for the storm to weaken as it crossed the Gulf Stream on approach to Atlantic Canada. Hurricane Juan made landfall just west of Halifax shortly past midnight on Sept. 29, 2003, with maximum sustained winds of 160 km/h.
