They propose a sixth category for storms with winds that exceed 192 miles per hour (309 kilometers per hour). Currently, storms with winds of 157 mph (252 kilometers per hour) or higher are Category 5. From time to time, experts have proposed a Category 6, especially since Typhoon Haiyan reached 195 mph wind speeds (315 kilometers per hour) over the open Pacific. Wehner said that as temperatures rise, the number of days with conditions ripe for potential Category 6 storms in the Gulf of Mexico will grow. “Perhaps I'll change my tune when a rapidly intensifying storm in the Gulf achieves a Category 6,” Corbosiero said in an email.

☆ Opinion | Acapulco Saw the Future of Hurricanes: More Sudden and Furious

Although, conventionally, hurricanes are measured by their peak intensity, how quickly they reach that intensity and how rapidly they approach land matters enormously. A tropical storm isn’t an insignificant threat, and what became Otis surely would’ve damaged Acapulco even if it hadn’t ever intensified. But a Category 5 is a threat of a different order, requiring an entirely different scale of preparatory response. You simply can’t evacuate a city of one million in just a few hours — at least, it’s never been managed before. It was the surprise of the storm’s transformation, with few of the conventional forecasting models predicting any significant intensification at all.

BOSTON (AP) — When it comes to hurricanes, New England can't compete with Florida or the Caribbean. Lee remained a Category 1 hurricane late Friday night with sustained winds of 80 mph (128 kph). One recent study found climate change could result in hurricanes expanding their reach more often into mid-latitude regions, which include New York, Boston and even Beijing. While hurricanes and tropical storms are uncommon in New England, the region has been seen its share of violent weather events. The Great New England Hurricane of 1938 brought gusts as high as 186 mph (300 kph) and sustained winds of 121 mph (195 kph) at Massachusetts’ Blue Hill Observatory.

But scientists said Friday that the arrival of storms like Hurricane Lee this weekend could become more common in the region as the planet warms, including in places such as the Gulf of Maine. One recent study found climate change could result in hurricanes expanding their reach more often into mid-latitude regions, which includes New York, Boston and even Beijing. Lee remained a hurricane with 80 mph (128 kph) winds at 2 p.m. EDT Friday as it headed toward New England and eastern Canada with 20-foot (6-meter) ocean swells, strong winds and rain. While hurricanes and tropical storms are uncommon in New England, the region has been seen its share of violent weather events. The Great New England Hurricane of 1938 brought gusts as high as 186 mph (300 kph) and sustained winds of 121 mph (195 kph) at Massachusetts’ Blue Hill Observatory.

ATLANTA (AP) — Hurricane Lee is rewriting old rules of meteorology, leaving experts astonished at how rapidly it grew into a goliath Category 5 hurricane. Political Cartoons View All 1148 Images"That extra heat comes back to manifest itself at some point, and one of the ways it does is through stronger hurricanes,” Shepherd said. More intense major hurricanes are also threatening communities farther inland, since the monster storms can grow so powerful that they remain dangerous hurricanes for longer distances over land. It has been 69 years since a major hurricane made landfall in New England, McNoldy said. Margot is far to the east of Lee, but as Margot strengthens it could affect the weather systems in the region that steer hurricanes.

Higher winds. In a 2018 paper, Dr. Kossin wrote that hurricanes over the United States had slowed 17 percent since 1947. Dr. Kossin likened the problem to walking around your back yard while using a hose to spray water on the ground. Because warmer water helps fuel hurricanes, climate change is enlarging the zone where hurricanes can form. There is a “migration of tropical cyclones out of the tropics and toward subtropics and middle latitudes,” Dr. Kossin said.

☆ Hurricanes of Data: The Tiny Craft Mapping Superstorms at Sea

The Tiny Craft Mapping Superstorms at Sea Shortly after dawn on Sept. 30, 2021, Richard Jenkins watched a Category 4 hurricane overrun his life’s work. That August, a sister ship, SD 1031, successfully entered Tropical Storm Henri, but only in its early stages. Hurricane research, modeling and forecasting requires many terabytes of data for every square mile the storm passes through, including vitally important sea-level data from inside a storm. The next day, the depression was upgraded to a tropical storm and officially given the name Sam. And four months later, Tropical Storm Megi killed more than 150, wiped out several villages with landslides and displaced more than a million people.
