The plume causing the worst dust storm in decades in some countries of the Caribbean is heading to the United States, but should not move as far north as Canada. The dust of the Sahara desert in Africa has crossed the Atlantic ocean and travelled to the Caribbean over the weekend.
The sky was obscured to a certain extent, some researchers in meteorology say they have never seen before.
The plume is now en route to the United States, the forecasts predicting that parts of Texas will wake up in a misty sky on Thursday, with the layer of dust thicker arriving Friday.
The latest forecast of the U. S. National Weather Service show that the plume then turns to the east, spending several days in States like Alabama and Georgia, and then weakening and overturning in the Atlantic ocean in the middle of the week.
At no time, the projection does suggest that a significant amount of dust penetrates in Canada.
Although it is not uncommon for the dust from the sahara crosses the Atlantic – it is a natural phenomenon, a regular and a visible plume reached the Americas every few years or so – the intensity of the dust cloud present is unusually high.
It is even visible from the international space Station.
In addition to creating a hazy effect in the sky, the dust particles diffuse the sun’s rays at dawn and dusk, creating what has been described as beautiful effects on sunrises and sunsets.
The particles may also travel at ground level, potentially affecting people who are allergic to dust.
