The Sahara Desert, known as one of the driest and harshest environments on Earth, has recently experienced an extraordinary and rare weather event: flooding. After intense rainfall hit parts of southeastern Morocco, lakes have appeared in this barren landscape for the first time in decades. This event has transformed the normally arid desert into a breathtaking scene of lakes and wetlands amid the iconic sand dunes.

A Record Rainfall

Over the course of two days in September 2024, the region was struck by heavy rainfall, especially around Errachidia, a desert city in southeast Morocco. Preliminary NASA data showed nearly 8 inches of rain in some parts of the Sahara, with Errachidia recording 3 inches, which is more than four times its usual rainfall for the entire month of September.

Houssine Youabeb from Morocco’s meteorology agency commented that it’s been “30 to 50 years since we’ve had this much rain in such a short space of time.” This rain was the result of a low-pressure system moving across the northwestern part of the desert.

Lakes Carved Into the Sand Dunes

As the rain poured over the Sahara’s desert terrain, it formed new lakes, creating a surreal landscape that contrasted with the usual dryness. In the desert town of Merzouga, the heavy downpour carved new lakes into the sand dunes, providing locals and visitors with a rare view of palm trees and sand dunes reflected in shimmering bodies of water.

One of the most striking changes occurred in Iriqui National Park, Morocco’s largest national park, where normally dry lakebeds were filled with water. NASA's satellite images, which use false color to highlight floodwaters, show the formation of new lakes across vast areas of the Sahara Desert.

Climate Change and Future Flood Events

While the rain brought a temporary transformation to the Sahara, it also raised concerns. Climate change is thought to be contributing to more frequent extreme weather events like this, as rising global temperatures disrupt normal weather patterns and the water cycle. Studies suggest that the Sahara may see more of these unusual events in the future, with potentially more severe floods in this historically dry region.

Though the flooding primarily impacted remote areas, some towns and villages were affected by flash floods, causing deadly incidents and damage. The Sahara Desert, spanning 3.6 million square miles, might experience more green patches and water bodies as storms push further north, with unknown long-term impacts on the desert's ecosystem.

This rare flooding event provides a glimpse into the changes that the world’s largest non-polar desert may experience as climate patterns shift due to human activity. Only time will tell what the Sahara will look like in the years to come.

Conclusion

The sight of lakes forming in the Sahara Desert is a reminder of nature’s unpredictability. For decades, the world’s largest desert remained dry, but with just a few days of rain, its landscape was dramatically altered. As scientists continue to study the effects of climate change, this flooding may be a precursor to more dramatic shifts in desert environments.
