The first hurricane of the fall season is expected to strike the Gulf Coast overnight, marking the latest onset of hurricane season in living memory. As of early Friday afternoon, Hurricane Isaias had grown to a Category 3 storm, with sustained winds of 120 miles per hour. It will strike along the shores of the Florida Panhandle, Alabama, and Mississippi, posing a threat to life and property for millions of Americans. Weather forecasters anticipate between 8 and 12 inches of rain in the areas near where the storm makes landfall.

Isaias’s imminent arrival signals the end of a period of unusual good luck when it comes to hurricanes striking the United States. Last year, no hurricanes reached the US mainland at all. And this year, Isaias is breaking a more than 100-year-old record: October 9 is the latest date since 1905 for the first Atlantic hurricane of the season to take shape. August and September have historically been the busiest periods of hurricane season.

Not lately, though. It’s a strange recent phenomenon, and it’s been even more fortuitous than it would ordinarily be. That’s because the Trump administration has slashed weather forecasting and emergency relief funding over the past two years, leaving us less prepared for a disaster. 

And now our luck seems to be running out — with even more rough weather on the way.

Hurricane season may be quieter than usual — but El Niño is on the way

Here’s the secret ingredient that’s pushed off hurricanes even as warming planetary temperatures raise concerns about more extreme weather events: El Niño. This notorious shift in global wind patterns, which occurs every two to seven years, moves warm water around the oceans, disrupting traditional weather patterns and leading to intense rain and sometimes disastrous flooding, as well as droughts. If there is an upside, however, it’s that this temporary change in ocean conditions prevents hurricanes from forming as frequently as they otherwise would.

The downside is, well, El Niño is still on its way. Forecasters expect this year’s version to be historically bad — using words like “super” or “Godzilla” to describe it. The worst of the bad weather is projected to arrive in December: The southern half of the continental US is expected to see unusually rainy and stormy weather, while areas of the Great Lakes and Pacific Northwest could see extreme dry spells. 

It will also serve as a crucial test of our reduced capacity for predicting and responding to disasters. Trump’s “big beautiful bill” cut funding for the National Oceanic and Atmospheric Administration’s weather forecasting and public alert programs by $200 million, and 17 percent of FEMA’s workforce left the agency in 2025 amid the administration’s DOGE purge. 

For now, if you’re in the danger zone for Isaias, please pay attention to local and national weather alerts this weekend. If you’re not, count yourself lucky — but there are storm clouds on the horizon.

➨ These days, it feels like we’re all swimming in a sea of AI hype and hysteria — all the ways this technology will make our lives better, all the ways it could kill every single one of us. But what if the two are more related than we think? Eric Levitz’s new piece asks whether the AI companies themselves warning us about the apocalypse is part of their own marketing strategy. It’s a useful guide for how to think about all of these existential conversations.

The world’s largest penguin colony has declined by two-thirds since 2011, most likely because of the climate crisis, a study has revealed. Scientists said the rapid demise of chinstrap penguins on Zavodovski, the northernmost of the South Sandwich Islands in Antarctica, increased the risk of a wider ecosystem collapse.

“It is an enormous population crash, equivalent to half a million breeding individuals being lost from that island,” said the leader of the research, professor Norman Ratcliffe, a penguin ecologist at the British Antarctic Survey.

The Guardian reported in 2020 that chinstrap penguin populations were decreasing on Low in the South Shetland Islands, prompting concerns among scientists that “something is broken” in the world’s wildest ecosystem. The new study, published on Wednesday in the journal Current Biology, indicates that the speed of collapse may be accelerating so rapidly that the distinctive bird — which gets its name from a black line that runs below the beak from cheek to cheek — may need to be classified as an endangered species.

Zavodovski Island had by far the biggest penguin colony in the world, with about 600,000 chinstraps and 90,000 macaroni penguins when the population was measured in 2011. Given the decline between then and 2025, it is likely to have lost that title to Cape Adare in the Ross Sea.

Scientists believe the most likely cause is climate disruption. Human-driven heating has pushed up winter temperatures on and around the Antarctic Peninsula to 5 degrees Celsius above preindustrial levels, one of the fastest rises in the world. On 6 June, the Argentinian Esperanza base on the Trinity Peninsula registered a record winter high of 15.4°C, about 20°C above normal for the time of year — a margin that scientists described as “absolutely crazy.”

Chinstrap penguins are struggling to adapt because they have special diets and specific ocean temperature preferences. Tracking data shows they prefer to forage in cooler waters to the northwest of the island, where they would expect to find Antarctic krill, which make up the bulk of their diet. But as the waters warm, the krill have moved south into the Weddell Sea.

Macaroni penguins, by contrast, are less fussy eaters and their numbers rose 30 percent — though not nearly enough to make up for the loss of chinstraps. Ratcliffe said this was only small comfort because if current trends continued, all penguins would run out of space.

He said the loss of chinstrap penguins would have wider repercussions for food webs. “Each ecosystem could be regarded as like a giant Jenga set, and every component that you remove increases the risk of ecosystems collapsing completely.”

The scientists ruled out several other possible causes of decline. There was no sign that chinstrap and macaroni penguins were in competition for food. The nearest humans lived thousands of miles away.

Although the island is volcanic and had a major eruption in 2016, prompting a “Penguin Pompeii hypothesis” of a sudden population fall, this theory was not borne out either by the data, which showed a steady linear decline, or by observations that showed the chinstraps avoided the main “asphyxia plain” area where the ash and lava were deposited.
