Another round of Saharan dust will move into the Gulf of Mexico and bring a haze along the Gulf Coast starting Tuesday.

The Saharan Air Layer has been incredibly impressive this year. The dry air mass, known as SALmostly travels above the ocean surface at 5,000 to 20,000 feet. It causes sinking air and shear, which inhibits tropical activity over the Atlantic Ocean.

The thick layer of Saharan dust continues to flow off the coast of Africa across the Atlantic and into the Caribbean, Gulf of Mexico and into the southeastern U.S.

While the latest round won't be as thick or as widespread as the past weekend, dust will be seen from Tuesday to Thursday from Texas to Louisiana.

Coastal areas, such as the Houston area and New Orleans, may see hazy skies in the days ahead.

The dust may continue to cause respiratory issues for sensitive groups.

Otherwise, dust in the atmosphere prevents hurricane development, and no activity is expected across the Atlantic for at least the next week.

The dry Saharan air that's blown off the coast of Africa and filled the lower latitudes has helped put a pause on what's been an active hurricane season so far. According to NOAA, the dry, dusty air has about 50 percent less moisture than the typical tropical atmosphere, which weakens any disturbance that tries to develop.

So far in 2020, two tropical storms, Arthur and Bertha -- both in the Atlantic -- already formed this year in May.

The third named storm, Cristobalswept from Louisiana to the Upper Midwest earlier this month, bringing high winds and heavy rain. Tropical Storm Dolly became the fourth named storm of 2020 last Tuesday after forming far from land over the North Atlantic.

There are as many as 13 to 19 named storms predicted during the Atlantic hurricane season, which runs from June 1 to Nov. 30, forecasters from the National Oceanic and Atmospheric Administration's (NOAA) Climate Prediction Center (CPC) said last month.

Six to 10 of those could develop into hurricanes, with winds of 74 mph or more, and three to six could even become major hurricanes, capable of inflicting devastating damage.

This forecast is well above the averages of 12 named tropical stormssix hurricanes, and three major hurricanes during the season.
