1Weather experts say the storm Hurricane Beryl might represent the beginning of a very active and dangerous hurricane season.
2"It's the earliest Category 5 hurricane on record in the Atlantic, Caribbean and Central American basin," a World Meteorological Organization (WMO) spokesperson said of Beryl.
3A Category 5 hurricane brings winds of 252 kilometers an hour or higher.
4Such storms can cause huge damage, including destruction of homes, roads, and bridges.
5The WMO spokesperson noted that destructive power, saying "it only takes one land-falling hurricane to set back decades of development."
6Beryl is on an unusually southern path, especially for a major hurricane, said Kristen Corbosiero of the University at Albany.
7Colorado State University hurricane researcher Phil Klotzbach said Beryl is possibly a sign of "more interesting stuff" that could happen in the near future.
8He added that there could be "several of these kinds of storms coming down later."
9The water temperature around Beryl is about 1 to 2 degrees Celsius above normal, at 29 Celsius, which "is great if you are a hurricane," Klotzbach said.
10Warm water acts as fuel for the thunderstorms and clouds that form hurricanes.
11The warmer the water and the air at the bottom of the storm, the better the chance it will rise higher in the atmosphere and create larger thunderstorms, said Corbosiero.
12It is not just hot water at the surface that matters.
13The ocean heat content, which measures deeper water, is far above record levels for this time of year.
14The levels are currently at what the highest September levels should be, University of Miami researcher Brian McNoldy said.
15This year, there is also a big difference between water temperature and upper air temperature throughout the tropics.
16The greater that difference is, the more likely it becomes that storms will form and get bigger, said MIT hurricane expert Kerry Emanuel.
17"The Atlantic relative to the rest of the tropics is as warm as I've seen," he said.
18Atlantic waters have been unusually hot since March 2023 and record warm since April 2023.
19Klotzbach said a high-pressure system that normally sets up cooling trade winds collapsed then and has not returned.
20Corbosiero said scientists are debating what exactly climate change does to hurricanes.
21But she said scientists have come to an agreement that climate change makes hurricanes more likely to become strong quickly, as Beryl did, and increases the strongest storms.
22Emanuel said the slowing of Atlantic ocean currents, likely caused by climate change, may also be a factor in the warm water.
23La Nina, which is a slight cooling of the Pacific that changes weather worldwide, also may be a factor.
24Experts say La Nina tends to reduce high altitude winds that weaken hurricanes.
25La Nina also usually means more hurricanes in the Atlantic and fewer in the Pacific.
26The Eastern Pacific had zero storms in May and June, something that has only happened twice before, Klotzbach said.
27Globally, this may be a below average year for tropical cyclones, except in the Atlantic.
