Top 11 Most Powerful Atlantic Hurricanes of All Time

Top 11 Most Powerful Atlantic Hurricanes

If you live in the United States, spring has sprung, and summer is well on its way. And if you live on the east coast of the United States, that means hurricane season is almost here. Typically recognized as running from June 1 - November 30 in the United States, the peak of Atlantic hurricane season is usually around September 10th of each year.

Approximately 10 storms develop into "named storms" each year - these storms are seen as being significant enough to merit naming by the NOAA. Of these storms, around 6 become hurricanes each year, and around 2.5 become “major” hurricanes of category 3 or greater. Most of these hurricanes are relatively harmless and end up dispersing before doing significant damage.

But every once in awhile, weather conditions are perfect for creating devastating storms that swell in size, intensity, and speed. These storms represent a serious danger to both people and property, and usually require emergency evacuation procedures.

In order to give you an idea of the size, intensity, and damage caused by these storms, we'll take a look at the top 11 most powerful Atlantic hurricanes of all time, and how they have affected the United States over the years.

NOTE: As per NOAA guidelines, these storms have been arranged by pressure - from lowest to highest. While storms are often ranked by wind speed alone, the NOAA prefers to rank storms by pressure.


Hurricane Ivan (2004)

11. Hurricane Ivan (2004)

Hurricane Ivan Statistics

  • Category: 5
  • Pressure: 910 hPa
  • Peak Sustained Winds: 165 mph
  • Total Damage: $22.8 billion (adjusted for inflation)
  • States Affected: Florida, Alabama, North Carolina, Georgia, Mississippi, Louisiana


Hurricane Ivan was the ninth named storm and the sixth hurricane to occur during the relatively active 2004 hurricane season. The storm system began forming in early September, around the peak of oceanic activity for the 2004 Atlantic hurricane season.

Hurricane Ivan began to form September 2, 2004, southwest of Cape Verde. The system began moving west, and began to strengthen gradually. It became classified as a tropical storm by September 3, 2004, and by September 5, it had reached hurricane status.

By September 9, winds in the hurricane had intensified to 160 mph, as it passed around Jamaica and headed westward towards the United States. Peak strength was reached on September 12, 2004, when the hurricane passed through the Yucatán Channel.

The storm then began to weaken slightly to category 4 strength before making landfall on the Gulf Coast of the United States. In Louisiana and Mississippi, thousands of Americans were evacuated. In Florida, thousands of homes were destroyed, and multiple bridges were heavily damaged by the high winds of Hurricane Ivan.

According to the NOAA, Hurricane Ivan is the 6th costliest hurricane to make landfall in the United States, with damages at $22.8 billion, adjusted for inflation.


Hurricane Cuba (1924)

10. Hurricane "Cuba" (1924)

Hurricane "Cuba" Statistics

  • Category: 5
  • Pressure: 910 hPa
  • Peak Sustained Winds: 165 mph
  • Total Damage: Not recorded
  • States Affected: Florida


Measured before the NOAA began naming storms, Hurricane Cuba is the earliest hurricane to be classified as a category 5 on the Saffir-Simpson scale, and its low pressure of 910 hPa places it at tenth on our list of the most intense Atlantic hurricanes.

This hurricane formed on October 141924 in the Caribbean, and began picking up steam as it moved in a northwesterly direction. By October 16, it had officially attained hurricane status.

By October 18, the hurricane had peaked at an intensity of 910 hPa, and sustained winds of over 165 mph. Almost immediately after the hurricane hit peak strength, it made contact with Cuba. To this day, it is the most powerful hurricane to have ever hit the country.

After moving past Cuba, the hurricane weakened quite a bit, reaching Florida with peak winds of around 90mph. Despite the catastrophic damage done to Cuba, Florida was relatively unaffected. There were no reported fatalities, though heavy rainfall occurred all throughout the state.

Staying Safe This Summer – How to Prepare for Peak Thunderstorm Season

Top 6 Summer Weather Safety Tips


The summer heat is still in full effect this August - and that means that throughout America, it's peak thunderstorm season. Typically, thunderstorms are the most dangerous in the Midwest throughout the entire summer - and peak season runs from May to late August.

Why are severe thunderstorms so much more common during the summer? During the warm summer months, cold air retreats to the north - and it brings warm, moist air with it.

This creates an unstable atmosphere that's conducive to massive supercells and thunderstorms - creating heavy winds, rain, hail, or even tornadoes, if conditions are right. Severe thunderstorms can be incredibly dangerous - so it's best to have a plan in place to deal with them, and stay safe during peak season!


Check Forecast - Top 6 Summer Weather Safety Tips

1. Always Check the Forecast

Checking the weather forecast is probably already part of your daily routine - but it's still important. Major thunderstorms can develop rapidly in only hours. If you're totally unprepared, you could be in danger of getting trapped in a parking lot, road, or other flooded areas. You could also be stuck outside during a dangerous hailstorm.

The first step to staying safe is to be informed - so whether you prefer checking the weather on TV, or using a smartphone app to see the daily forecast, make sure that you do so, especially if you see a large storm system rolling in.


Power Outages - Top 6 Summer Weather Safety Tips

2. Prepare for Power Outages

Large thunderstorms are the single most common cause of power outages. Lightning strikes can damage electrical grids directly, as can severe flooding. Strong winds and driving rain can also knock over electrical poles, smash trees, and render electrical wiring useless.

These power outages can resolve in a few hours - but may also require a few days. So be prepared for power outages - better safe than sorry! You'll want to have:

  • Ready-to-eat packaged food
  • A source of safe, potable water
  • Candles, lanterns, flashlights, and other light sources
  • A propane or gas-powered camping stove
  • First aid supplies 
  • Emergency cash (local stores may not be able to run credit cards during an outage)
  • Hand-cranked or battery powered emergency radio

Keep all of these things in a readily-accessible place, and it will be much easier to get through a power outage - whether it lasts two hours, or two days.
