October usually brings a weird energy to the Caribbean. The air gets heavy, the water is soup-warm, and meteorologists start living on caffeine. But 2024 took that typical seasonal stress and doubled it. Practically overnight, we went from watching a few disorganized blobs on satellite imagery to tracking two distinct threats. Tropical Storm Nadine and Hurricane Oscar didn't just form; they basically erupted into existence, leaving a lot of people—including some of the pros—scrambling to keep up.
It’s honestly rare to see two systems develop so close together in both time and geography, especially when they behave so differently. You had Nadine, a sprawling, messy rainmaker over the western Caribbean, and then Oscar, a "tiny" but fierce hurricane that underwent what experts call explosive intensification.
If you weren't paying close attention on that Saturday in mid-October, you might have missed how quickly the situation shifted from "watching the tropics" to "active landfalls."

What Really Happened With Tropical Storm Nadine and Oscar
Timing is everything. On October 19, 2024, the National Hurricane Center (NHC) had its hands full.
Nadine was the first to grab the spotlight. It started as a broad area of low pressure near Nicaragua around October 15. It wasn't particularly pretty to look at on satellite—just a big, disorganized mess of thunderstorms. But by the morning of the 19th, it had pulled itself together enough to be named a tropical storm. At that point, it was only about 160 miles east of Belize City.
The storm didn't waste time. It churned westward and slammed into Belize near Watters Bank around noon that same day.
While everyone was focused on Nadine's wind and rain in Central America, Oscar was pulling a "hold my beer" moment near the Turks and Caicos. Oscar was the ultimate overachiever. It went from a 10% chance of development to a full-blown hurricane in what felt like the blink of an eye. In just about six hours, Oscar jumped from a disorganized tropical wave to a Category 1 hurricane with 85 mph winds.
The Tale of Two Very Different Storms
Comparing these two is like comparing a minivan to a Ducati.
Nadine was huge. It had a massive wind field that stretched nearly 200 miles from its center. It wasn't about the wind speed, though—it topped out around 60 mph. The real story was the water. Nadine was a "rain machine," dumping upwards of 12 to 19 inches of rain in parts of Mexico and Belize.
Then you have Oscar.
Meteorologists like Brad Reinhart from the NHC noted that Oscar was one of the smallest hurricanes on record. Its hurricane-force winds only extended about 5 or 6 miles from the center. Think about that. You could be ten miles away and feel like it’s just a breezy day, while someone a few miles over is losing their roof. This "micro-hurricane" status is likely why the computer models missed it. Small storms are notoriously hard to predict because they can spin up—and collapse—faster than the global models can refresh.
The Human Toll and Regional Impact
We often talk about millibars and wind speeds, but the ground reality was much grimmer.
Nadine's remnants crossed over into the Pacific (where they eventually helped birth Hurricane Kristy), but the damage it left in Central America and Mexico was severe. In southeastern Mexico, the flooding was catastrophic.

- Chiapas and Veracruz: These states took the brunt of it. We're talking about more than 30,000 homes damaged in Veracruz alone.
- Fatalities: Sadly, the flooding and landslides from Nadine were linked to 13 deaths in Mexico.
- Belize Infrastructure: While Belize City avoided a direct catastrophe, the heavy rain caused major dams like Mollejon and Vaca to spill over, threatening downstream communities.
Oscar, meanwhile, took aim at the Greater Antilles. It made its first landfall on Grand Turk Island and then hit eastern Cuba near Baracoa.
Cuba was already in a desperate situation. The country was experiencing a total power grid failure just days before Oscar arrived. Imagine trying to track a hurricane on your phone or radio when you haven't had electricity for 48 hours. Oscar dumped over 24 inches of rain in some parts of Guantánamo province. It led to at least eight deaths and massive agricultural losses, specifically coffee and tomato crops that the local economy depends on.
Why the Models Got Oscar So Wrong
You might be wondering: how does a hurricane just "appear" with almost no warning?
Most weather models are designed to see the big picture. They’re great at spotting a massive system like Nadine days in advance. But Oscar was a "midget" storm. Because it was so compact, it was able to hide within the larger atmospheric noise until it was already intensifying.

AccuWeather actually took a bit of a victory lap during this period, claiming they spotted the development potential for Oscar five days before the NHC. Whether that's marketing or superior meteorology, the point remains: the standard tools we rely on for hurricane tracking have a serious blind spot when it comes to small, rapidly intensifying systems.
The Madden-Julian Oscillation (MJO)—a bit of a "pulse" of energy that travels around the tropics—wasn't even in a favorable phase for storm development. Usually, that means things stay quiet. But Oscar proved that if the water is warm enough (and the Caribbean was record-breakingly warm in 2024), a storm can find a way.
Practical Steps for the Next "Quick" Storm
If there is one thing we've learned from the Nadine and Oscar duo, it's that the "cone of uncertainty" isn't the only thing you should watch.
- Look at the Rainfall Totals: Nadine wasn't a "major" hurricane, but it killed more people than many Category 3 storms because of the rain. Don't ignore a tropical storm just because it doesn't have a "Hurricane" label.
- Trust Local Knowledge: In Cuba and Belize, local officials often have a better sense of which bridges will wash out first. If they say "move," you move.
- Keep an Analog Backup: If Oscar taught us anything, it’s that a battery-powered or hand-crank weather radio is non-negotiable. If the grid goes down like it did in Cuba, your high-tech apps are useless.
- Watch the "Invests": Before a storm gets a name, it's called an "Invest." If you see an Invest area with even a 10% or 20% chance of development near your location, start your basic prep. Oscar went from 10% to 100% in a single afternoon.
The 2024 season was a reminder that the Caribbean is getting more unpredictable. As sea surface temperatures continue to hover in record territory, these "pop-up" storms like Oscar and "rain-bombs" like Nadine are likely to become our new October reality.
Check your local emergency supplies now, especially if you live in a coastal area. Ensure your flashlights have fresh batteries and you have at least three days of water per person. These storms don't always give you a week's notice anymore—sometimes, you only get a few hours.
