Why This Hurricane Season Has Experts on Edge

June 1 marks the official start of the hurricane season in the Atlantic Ocean—and once again, the season looks like it will be busy.
Though it is impossible to tell this far in advance exactly when storms will form and where they might hit, the presence of hurricane-friendly environmental conditions this season—along with the federal government cuts and policy chaos —have experts worried about the accuracy of forecasts and the resulting safety of communities. Scientific American asked several forecasters and hurricane researchers what they were most concerned about this year.
Warm oceans may mean a busy hurricane season

Seasonal forecasts—including the National Oceanic and Atmospheric Administration's— put the odds in favor of having more storms than average this season, which will last until November 30. NOAA predicts 13 to 19 named storms, meaning those of tropical storm strength (with winds of 39 to 74 miles per hour) or higher. Of those, six to 10 are expected to become hurricanes (with winds of more than 74 mph). And among those hurricanes, three to five are expected to reach major hurricane status—meaning they will have winds that will fall within Category 3 (those of 111 to 129 mph) or a stronger category on the Saffir-Simpson scale.
The expectations of an active season arise from a combination of a favorable atmospheric environment and abundant ocean heat to fuel storms. For one thing, there's no El Niño in place right now to influence winds in a way that tends to shred storms apart, says Phil Klotzbach, a hurricane researcher at Colorado State University, whose team releases its own seasonal forecast each year.
And waters in the Gulf of Mexico are extremely warm right now, providing ample fuel for the convection that drives tropical cyclones. 'Over 60 percent of the Gulf is at record or near-record warmth for the time of year, and waters east of Florida and around the Bahamas are as warm as we've seen them for the start of any hurricane season in the satellite era,' says Michael Lowry, a hurricane specialist at WPLG Local 10 News in Miami. Warm ocean water in these areas can cause storms to rapidly intensify right before landfall, giving communities less time to prepare for the onslaught. This is a major concern for Jill Trepanier, a hurricane researcher at Louisiana State University. 'That is just a devastating situation when it occurs,' she says.
It's a situation that has played out many times in recent years, including with Hurricanes Beryl and Milton last season. 'The sticky heat of the Gulf is a worrisome trend that's undoubtedly fueling the spate of big hurricane hits along the Gulf Coast over the past decade or so,' Lowry says. 'This is consistent with recent research that suggests the Gulf has seen a significant increase over the past 42 years in the number of days where it can support high-end hurricanes.'
Because of that abundant hurricane fuel, 'I would not be surprised if we see early-season activity well ahead of the peak' of activity in September, says Marshall Shepherd, an atmospheric scientist at the University of Georgia.
Several experts noted that this year's conditions have some slight differences from the most recent seasons. For one, 'the waters of the deep tropical Atlantic east of the Caribbean—often a bellwether for overall hurricane season activity—are the coolest we've seen them to start a hurricane season since 2021,' Lowry says. But, he adds, they are 'still plenty warm ... and forecast to remain so, which should favor above-average activity.'
Though the overall message is that this will be a busier-than-normal season, it is not predicted to be quite as busy as those of the past few years. Klotzbach is worried that could lead to complacency. 'My biggest concern is that, because the seasonal forecasts are a bit less aggressive than last year..., people may tend to let their guard down,' he says.
Communities are still recovering
Inevitably, each time a new hurricane season begins, some communities are still reeling from storms from the previous year—and often even further back in time. This year 'places in Florida, Georgia and the Carolinas are still recovering from Helene, Milton and Debby,' Shepherd says, citing three of the worst storms of the 2024 season.
A National Academies of Sciences, Engineering, and Medicine report released last year warned that the Gulf Coast in particular risked being in 'perpetual disaster recovery' mode. The report noted that seven hurricanes struck the region in 2020 and 2021 alone.
It's entirely possible that some of the communities pummeled in recent years could face hurricane peril again this year. 'With projections of average to above-average activity, all it takes is one storm to compound an already bad situation for many people,' Marshall says.
NWS and FEMA cuts
Piled atop these concerns is the situation within the federal government, with substantial budget and staffing cuts to the National Weather Service (NWS) and the Federal Emergency Management Agency (FEMA). 'It remains to be seen what the impacts of reduced staffing across relevant NOAA offices and agencies will be,' says Brian McNoldy, a tropical storm researcher at the University of Miami. 'But any loss of expertise, data collection capabilities and around-the-clock monitoring is troubling during critical, high-impact situations.'
Though the National Hurricane Center (NHC) monitors the development of tropical storms and hurricanes and produces the main forecasts, local NWS offices still play a crucial role in providing more localized warnings about storm surge, flooding and winds. Many offices in hurricane-prone areas are understaffed, says Jeff Masters, a writer at Yale Climate Connections and a former Hurricane Hunter at NOAA. Among those, the NWS's Houston and Miami offices are suffering the largest staff shortages. The NWS has asked staff from other offices to move into some of these open slots.
Lowry and Masters also point out that the cuts have reduced the number of weather balloons launches. Balloon data are crucial for understanding the larger atmospheric patterns that determine where a hurricane will go—and who might need to evacuate or take other precautions.
There is one positive note: 'I was very pleased to see the Hurricane Hunters reinstated,' Trepanier says, referring to three of the meteorologists who fly specialized, equipment-laden planes directly into storms to gather data that significantly improve forecasts. 'Though it isn't enough to offset the concern, it is a move in a good direction.'
James Franklin, former chief of the NHC's Hurricane Specialist Unit, says he is concerned about trainings for emergency managers that were canceled earlier this year Their absence could leave areas less prepared and less able to know what decisions to make based on forecasts. 'When training has to be cut down…, it just makes those kinds of mistakes on the emergency management side more likely to occur,' he says.
Finally, another big worry is simply the government's ability to respond with help for victims when a storm hits. Masters' biggest worry is that FEMA won't 'be capable of managing a major disaster right now.'
Reports by CNN and other news outlets have cited internal FEMA memos that report the loss of 30 percent of full-time staff. 'I wrote the plan FEMA uses to respond to hurricanes,' says Lowry, a former employee of both the NHC and FEMA, 'and it's hard to imagine the agency will be able to meet its mission-critical functions this season with such depleted staffing and without a fully revised plan.'
