Atlantic hurricane season is from June to November. Activity peaks around September 10.
Mother Earth spins storms off her equatorial girdle like a sweating goddess. Trade Winds and currents flow from Senegal/Gambia in West Africa straight to the Caribbean and then turn up the East Coast around the Bermuda high pressure system. The winds bring Sahara Sandstorms to the Caribbean and tropical storms that sometimes grow into hurricanes.
In the past these same winds and currents brought colonizers. Puerto Rico was the first good water stop. The word “hurricane” comes from the Spanish “huracán,” but is actually a Taíno word “hurakán” which means god of the storm. Most hurricanes would rise over the island from the east, over El Yunque, the sacred mountain of Puerto Rico. From most of the island, the storms would seem to be rising right out of the mountain.
You can see the effects of warming in the ocean’s daily cycle. The wind and waves are calmer in the morning, but as the day heats up, winds and waves grow into the afternoon. This is not global warming. It’s just the daily cycle. But it is a clear example of what happens when heat gets put into the oceans. That’s what is happening now with Global Heating. Storms are intensifying.
Hurricane Season 2022
The 2022 Hurricane Season is June to November. The season peaks on September 11.
Hurricane Season 2021
Hurricane season 2021 runs from Tuesday, June 1 to Tuesday, November 30, 2021. NOAA is warning of another strong hurricane season.
A climate scientist at Colorado State University predicts 8 hurricanes (25% above average), 4 major ones (48% above average) and 80 named storms in total (35% above average).
The first tropical storm in the Pacific came in early May.

Beaches are closed, although surfing is allowed in certain areas.
Monday, August 3, 2020

2020 Hurricane Names
The season begins with a list of names for tropical storms that become hurricanes.
This year they are:
- Arthur ~ Formed on May 16, 2020.
- Isaias became a tropical storm south of Puerto Rico on July 30, a hurricane over the Carolinas on August 3, and a tropical storm over New York City on August 4. It killed people, damaged homes and knocked out power in Metropolitan New York City. It’s the worst storm in NYC since Hurricane Sandy.
- Josephine petered out on August, 16, 2020.
- Laura became an Atlantic tropical storm as it approached the Lesser Antilles on Friday, August 21.
Sounds like the Gran Combo song, “Me Libere.”
These storms are called “cyclones” because they cycle around a low-pressure center. Cyclones start as Tropical Depressions. When wind speeds rise above 39MPH, they are called Tropical Storms and given names in alphabetical order through the season. Cyclones are called “Hurricanes” (typhoons in Asia) when sustained winds reach 74 mph or more. Major Hurricanes have wind speeds above 110 mph.
- Tropical Depressions (unstructured storms) are numbered One, Two, Three…
- Tropical Storms are named when winds rise above 39 mph. Arthur, Bertha, Cristobal…
- Hurricanes occur when winds rise above 74 mph
- Major Hurricanes occur when winds rise above 110 mph
Hurricanes cause damage with high winds and heavy rains. Storm surge, a wall of water pushed ahead of the storm, is especially dangerous in coastal areas.
The Caribbean is the most affected region, but hurricanes often turn and move up the Atlantic Coast. They can reach New York. Remember Hurricane Sandy in 2012? Some of the damage still hasn’t been repaired. Hurricanes affect New York even if they stay in the Caribbean because many Latin New Yorkers have family in the islands.
The average number of hurricanes in a season is about 12. It’s been as high as 28 and as low as 4.
Many Caribbean islands get seriously hit every 10 or 20 years at the most. So Caribbean life is designed around hurricanes. They are part of the natural cycle, Indigenous cosmology and everyday life.
Sometimes cyclones also bring change. The Haitian Revolution began as a Hurricane approached.
Atlantic Hurricane Formation
The Azores or Bermuda-Azores High is a semi-permanent high-pressure system over the central Atlantic. It moves over the Azores in the East Atlantic in summer and over Bermuda in the West Atlantic in winter.
Summer weather (low pressure) rotates around this high pressure system in a clockwise direction.
Warm dry Mediterranean/Sahara air moves south over West Africa where it picks up moisture. From there, trade winds and ocean currents push the storms across the Atlantic towards the Caribbean islands, Florida and the U.S. Atlantic coast.
The strength and position of the high pressure system determines whether storms stay in the Caribbean, hit the South or Florida, or move even further up the coast. The El Niño temperature oscillation in the Pacific also affects the intensity of Atlantic hurricanes.
Climate change is increasing the strength and frequency of hurricanes. We are currently in an above-average storm cycle that began in 2016.
Hurricane Sandy made it all the way to New York City in October-November 2012. It did about $70 billion in damage.
Hurricane Maria destroyed Puerto Rico in 2017. Two years after a failed FEMA response led by the Trump-McConnell Republican GOP, over 20,000 people are reported to still be living under blue tarps. President Trump helped us out by throwing rolls of paper towels.
