The Saharan Dust

First….I take MoMo for her walk at 5 am because it is a bit cooler…that is until this morning…..at 5 am it was 90 degrees with 85% humidity….just a flippin’ joy. (sarcasm)

Now onto the Big News for the Coast……

This weekend the massive dust cloud that originated from the Sahara should make it to our neck of the world….the problem is we may not get much spectacular sights for it is forecast to be overcast for most of the week.

So I will post photos if I get a chance….until then how about some facts about this “cloud”……

Expansive dust clouds arise from the sun-baked Sahara each year, making the 5,000-mile journey across the Atlantic Ocean to the southern United States. While these dust plumes tend to stay intact while traveling across the ocean, they typically diffuse by the time they hit the Caribbean. But this year, things are different.

This month’s dust cloud is more resilient than usual—its dust is so opaque and thick that it can be clearly seen from the International Space Station, while its predecessors have been ghostly and faint from space. Astronaut Doug Hurley photographed the cloud from the ISS on June 21, tweeting, “We flew over this Saharan dust plume today in the west central Atlantic. Amazing how large an area it covers!”

These dust plumes, called the Saharan Air Layer (or SAL) are born when severe wind storms strike the Sahara. Entering the Atlantic Ocean at the Intertropical Convergence Zone, the plumes catch on to the trade winds, which run east-west along the equator.

The dust is already covering Caribbean skies, and Gulf Coast states like Texas and Louisiana should expect to confront this vast cloud on Wednesday and Thursday. Before the cloud enters the US here’s what you should know about the plumes.

That is all I have for this Sunday….hopefully you learned a bit and were entertained…..come Monday it is back to the news in the spotlight…..

Be Well…..Be Safe…..

  1. We have had some Sahara dust in the past, but it looks like we will be missing it this year, due to strong winds prevailing around the UK.
    Best wishes, Pete.

  2. Reblogged this on It Is What It Is and commented:
    It hit Puerto Rico first … ALL of the Island was covered! … “These dust plumes, called the Saharan Air Layer (or SAL) are born when severe wind storms strike the Sahara.
