Saharan Dust Storm: 13 Surprising Ways It Might Impact You Play Pause Unmute Mute Amidst the craziness of the pandemic, a giant Saharan dust plume has made its way across the Atlantic Ocean. It has started affecting the United States, as well as the rest of North America and the Caribbean. Today, we’re going to look at 13 facts about Saharan Sand Storms. We’ll also discuss how they can make it across the Atlantic and how the current storm will impact your day-to-day life. 1. Sahara Means “The Greatest Desert” in Arabic The Sahara is appropriately named, as it is the largest hot desert in the world. It covers the northern third of Africa and is comparable in size to countries such as the United States, Canada, and China. Much of the desert is uninhabited. Rain is nearly non-existent, with the Sahara averaging about 20 millimeters (0.8 inches) of rain per year. Its residents live on the coast and on the far outer fringes of the desert. Sand temperatures over 80°C (176°F) have been recorded in the Sahara. There are no roads across the Sahara, but a 4,500 km (2,800 mi) Trans-Saharan Highway that runs north/south from Algiers, Algeria to Lagos, Nigeria is in the works. A few brave peop…

Saharan dust settles over hurricane breeding grounds – What it means for hurricane season As hurricane season shifts into high gear, an expansive Saharan dust plume could act as a protective shield across the Atlantic, making it more difficult for storms to organize and strengthen.

How Saharan dust regulates hurricane rainfall | ScienceDaily Giant plumes of Sahara Desert dust that gust across the Atlantic can suppress hurricane formation over the ocean and affect weather in North America. But thick dust plumes can also lead to heavier rainfall -- and potentially more destruction -- from landfalling storms, according to a July 24 study inScience Advances.The research shows a previously unknown relationship between hurricane rainfall and Saharan dust plumes. "Surprisingly, the leading factor controlling hurricane precipitation is not, as traditionally thought, sea surface temperature or humidity in the atmosphere. Instead, it's Sahara dust," said the corresponding author Yuan Wang, an assistant professor of Earth system science at the Stanford Doerr School of Sustainability. Previous studies have found that Saharan dust transport may decline dramatically in the coming decades and hurricane rainfall will likely increase due to human-caused climate change. However, uncertainty remains around the questions of how climate change will affect outflows of dust from the Sahara andhow muchmore rainfall we should expect from future hurricanes. Additional questions s…

The Saharan Air Layer - Atlantic Oceanographic and Meteorological ... The Saharan Air Layer Studying Impacts of Transatlantic Saharan Dust Storms on Atlantic Oceanic and Atmospheric Phenomenon SCROLL TO LEARN MORE The Saharan Air Layer and Extreme Weather What Is the Saharan Air Layer? The Saharan Air Layer is a mass of very dry, dusty air that forms over the Sahara Desert during the late spring, summer, and early fall, and moves over the tropical North Atlantic every three to five days.  Saharan Air Layer outbreaks usually occupy a 2 to 2.5-mile-thick layer of the atmosphere with the base starting about 1 mile above the surface.  The warmth, dryness, and strong winds associated with the Saharan Air Layer have been shown to suppress tropical cyclone formation and intensification. Saharan Air Layer activity usually ramps up in mid-June, peaks from late June to mid-August, and begins to rapidly subside after mid-August.  During peak period, individual Saharan Air Layer outbreaks reach farther to the west (as far west as Florida, Central America and even Texas) and cover vast areas of the Atlantic (sometimes as large as the lower 48 United States). SAL activity usually ramps up in mi…

Saharan Dust: Nature's Hurricane Suppressant | Restoration ... Catastrophe Restoration Preparing to Respond: Hurricanes Saharan Dust: Nature’s Hurricane Suppressant Saharan Dust is suppressing the hurricanes this season, but restoration professionals must stay alert as peak season is here By Kayla McGowan Credit: Ashley Sheffield / iStock/ Getty Images Plus September 16, 2025 Just a little over three months ago, the 2025 Atlantic hurricane season started and is set to run through November 30. The first named storm was Tropical Storm Andrea on June 23, and since then, we’ve had an additional five storms, with Hurricane Erin a category 4. Of those six, none have made landfall in the US and there are $0 in damages reported. Though we never doubt what hurricane season can and will bring, there is one key factor that is contributing to the “slower” season. That variable is Saharan Dust. This is dry, mineral-rich particles that are lifted from the Sahara Desert and carried across the Atlantic Ocean by strong winds and it forms what we know as the Saharan Air Layer (SAL) 1 . When we think of dust, it’s what we see day in and day out, you see it, then it’s gone. Well, that isn’t the same …

A massive plume of dust from the Sahara Desert is coming to the US https://www.europesays.com/africa/311759/ This dust can impact hurricanes Did you know a massive plume of dust from Africa is on its…

Yeah, usually Saharan dust is detrimental to hurricane formation! It's a combination of the dry air and the ways the dust particles themselves interact with clouds and radiation. There's certain cases where a *little* dust can help, but dust being bad for hurricanes is a good generalization overall

African Dust Acts as Nature's Hurricane Shield Tan-toned dust pulsed from the Sahara Desert and over the Atlantic Ocean in early May 2025. A massive plume of Saharan dust has completed its 5,000-mile journey to South Florida, bringing with it a natural defense against hurricane formation that scientists are only beginning to fully understand. This phenomenon, known as the Saharan Air Layer, creates a “trifecta of atmospheric processes” that can shut down tropical storm development across the Atlantic Basin. However, this protective effect comes with a critical timing caveat that could determine whether the 2025 hurricane season becomes devastating or manageable for coastal communities. The dust outbreak represents just one of many that will emerge from Africa’s coast every three to five days during peak season, sometimes covering areas larger than the continental United States. The Dust Detective’s Discovery The story begins nearly 60 years ago when Joseph Prospero, now an emeritus professor at the University of Miami, made a discovery that would reshape hurricane science. Prospero, known as “the father of dust,” founded the Barbados Atmospheric Chemistry Observatory specifically …

How does Saharan dust impact hurricane season? - FOX Weather 03:48 A Dusty Forecast: Saharan Dust's Impact on Hurricane Season Saharan dust has arrived, and it's expected to play a key role in the 2026 Atlantic hurricane season. This massive plume of dry, dusty air contains ingredients that can suppress tropical development across the Atlantic, helping to limit storm formation and intensification. FOX Weather meteorologist Jane Minar explains what Saharan dust is, how it impacts the tropics and what it could mean for future storms throughout the hurricane season. A massive cloud of Saharan dust has swept thousands of miles across the Atlantic Ocean and settled over a key breeding ground for tropical storms , creating an environment that is hostile to hurricane development. The sprawling African airmass, that is showing little sign of departing anytime soon, is injecting dry, stable air into the region – playing a major factor in the Atlantic hurricane season as summer steps into full stride.

Phenomenon/a:Dust, Saharan Air LayerSatellite:GOES-19 (GOES East)Product:GeoColorInstrument:Advanced Baseline ImagerTimespan: May 28 - June 2, 2025 (6:00 – 23:50 UTC) A giant plume of dust from the Sahara Desert made its way from Africa to the United States to kick off the start of meteorological summer in the Northern Hemisphere. NOAA’s GOES-19 satellite captured this multi-day time lapse imagery of the dust blowing thousands of miles across the Atlantic from May 28th to June 2nd. The dust is due to a two to 2.5-mile-thick layer of the atmosphere, called theSaharan Air Layer, crossing over the Atlantic Ocean. The warmth, dryness and strong winds associated with this layer have been shown to suppress tropical cyclone formation and intensification. When it reaches the U.S., it can cause hazy skies as well as vivid sunrises and su…
