Hurricane season in the Atlantic brings a host of dramatic and dangerous weather, from whipping winds, torrential downpours, power outages and flash floods. And as climate change has been tied to an increase in hurricane intensity, these impacts could continue to worsen.

But when exactly does the Atlantic hurricane season of 2024 start, and how long does it last? And how do hurricanes form? What can people do to prepare in the face of the most dangerous storms on Earth?  The 2024 Atlantic hurricane season is predicted to bring a record-breaking number of ferocious storms. 

The National Oceanic and Atmospheric Administration has predicted an above-normal season, with up to 25 named storms, as a result of climate change and the transition from El Niño to La Niña.

The first tropical storm of 2024, Alberto, hit on June 19. 

What are hurricanes?

Hurricanes are tropical cyclones. When a tropical cyclone's sustained winds reach 39 to 73 mph (63 to 118 km/h), it is considered a tropical storm and it gets a name from a list put out by the World Meteorological Organization. Once those sustained winds reach 74 to 95 mph (119 to 153 km/h), that storm becomes a Category 1 hurricane. According to the Saffir-Simpson scale, here are the sustained winds linked to categories 2 through 5 hurricanes:

  • Category 2: 96 to 110 mph (154 to 177 km/h)
  • Category 3: 111 to 129 mph (178 to 208 km/h)
  • Category 4: 130 to 156 mph (209 to 251 km/h)
  • Category 5: 157 mph or higher (252 km/h or higher)

Named storms of 2024

  • Tropical Storm Alberto — June 19 -20
  • Tropical Storm Beryl — formed June 28 . This storm slammed into Grenada, Saint Vincent and the Grenadines as a Category 5 on Tuesday, July 2 and as of Wednesday (July 3) was making its way toward Jamaica as a major Category 4 storm.

How do hurricanes form?

Hurricanes are the most violent storms on Earth, according to NASA. At heart, hurricanes are fueled by just two ingredients: heat and water. Hurricanes are seeded over the warm waters above the equator, where the air above the ocean's surface takes in heat and moisture. As the hot air rises, it leaves a lower pressure region below it. This process repeats as air from higher pressure areas moves into the lower pressure area, heats up, and rises, in turn, producing swirls in the air, according to NASA. Once this hot air gets high enough into the atmosphere, it cools off and condenses into clouds. Now, the growing, swirling vortex of air and clouds grows and grows and can become a thunderstorm.

So, the first condition needed for hurricanes is warmer waters in the Atlantic Ocean, which cause a number of other conditions favorable to hurricanes.
