Massive Saharan dust cloud headed for Florida: What to know about the annual event

While the idea of a massive dust cloud from the deserts of Africa hitting 
the United States might seem like the plot of a sci-fi movie -- it's 
actually just an annual weather event that can give way to some 
spectacular seaside sunsets.

The dust mass, which forms in the Sahara Desert in northern Africa and 
blows thousands of miles across the Atlantic Ocean, is forecast to arrive 
in Florida this week.

The size of the cloud is approximately 2,000 miles wide from west to east 
and 750 miles long from north to south, according to Accuweather.

When will the dust cloud reach the U.S.?
The plume, which is visible from space via satellite imagery, began 
reaching Florida on Wednesday and will spread over more of the southeast 
by Thursday.

The weather phenomenon is a normal, annual event that is often present in 
the region from late June to mid-August.

Each year, the atmosphere transfers several hundred million tons of dust, 
made of minerals such as iron and phosphorus, across the Atlantic to the 
Caribbean, Central America and South America. The dust mainly affects 
Puerto Rico but can reach states, including Florida and Texas.

What does the Saharan dust cloud look like?
The dust plumes create colorful, picturesque sunrises and sunsets, giving 
way to deeper oranges and reds when the conditions allow it. Some say the 
dust cloud makes the sky appear "milkier" or "hazy gray" during the day.

Dry air from the dust cloud can limit the formation of tropical systems, 
but the moisture over Florida is likely to be stronger than the dust can 
squash.

If storms persist despite the Sahara dust cloud, the dust and rain 
combination could lend its way to dropping a mud-like consistency over the 
area.

Is the Saharan dust cloud bad for your health?
The presence of the Sahara dust in the atmosphere can also be harmful to 
health, according to the Centers for Disease Control.

Air quality can become poor as particulate matter increases in the air. 
Additionally, the particles can be breathed in, entering the lungs and 
bloodstream and affecting those with asthma and upper respiratory 
complications. Others have described feeling symptoms often related to 
allergies, the CDC reports.

Large particles from Sahara dust can also cause skin and eye irritation, 
the CDC said.

While anyone can be affected by Saharan dust, there are some groups at 
higher risk than others, including babies and children, older adults, 
people with underlying conditions and those with heart or lung conditions, 
according to the federal health agency.

Some studies suggest that exposure to desert dust events is associated 
with a higher risk of heart attacks, particularly in older and already 
vulnerable populations.

To protect one's health, the CDC recommends checking the local air quality 
index, reconsider spending time outdoors and, if you go outdoors, perform 
easy activities like walking as opposed to running.

How does the Saharan dust cloud impact the environment?
There are also benefits when it comes to how Saharan dust affects the 
ecosystem. For example, minerals in the dust, often rich in iron and 
phosphorus, can act like a fertilizer and help forests and other 
vegetation and soils gain nutrients.

Additionally, the ocean's phytoplankton and other marine life benefit from 
the minerals in the dust. This is important because phytoplankton are the 
beginning of the food chain in the ocean and help sequester significant 
amounts of carbon.

However, there are cons, including that dust can accumulate and cover 
plants, cutting off their ability to undergo photosynthesis, harming or 
killing the vegetation.

What's more, the dust could be hiding plant-like bacteria, which -- when 
deposited into the ocean -- can lead to harmful algal blooms, which can 
lead to a "red tide" of toxins in the oceans.

The dust can also aid in coral bleaching, along with other factors such as 
very warm water and ocean acidification.
