A huge dust cloud is heading towards Costa Rica. It originated in the Sahara Desert. This is something that happens annually, much to the despair of those with respiratory problems. It brings with it a stop to such heavy rain.
This year the cloud of dust is the largest we have seen in half a century. It’s currently over the Caribbean and heading towards Central America and the United States. Experts estimate it will reach us this Tuesday.
We will have reduced vision due to the dust from thousands of miles away. We will also see haze and red sunsets. Allergy sufferers are advised to stay indoors. The use of masks and glasses can also help. Airplane pilots will notice a reduction in visibility in the morning and afternoon.
The clouds form and then cross the north Atlantic every three to five days from late spring to early fall. They can cause a 3-kilometer-high layer.
