Why is the Danakil Plain in Eritrea nearly rainless?

The interior regions of the Danakil Plain are practically rainless due to the region's unique geography and climate patterns.

While the highlands and western lowlands of Eritrea receive summer rainfall from a southwesterly airstream, the eastern edges of the plateau and the coastal fringes receive only limited precipitation from a northeasterly airstream during the winter and spring. The Danakil Plain, which is part of the East African Rift System, is separated from the Red Sea by a series of live volcanoes and is sharply delimited to the west by the eastern escarpment of the plateau. This topography creates a rain shadow effect, preventing significant moisture from reaching the interior of the plain. Any water that does enter the area typically evaporates, as the region is characterized by extreme aridity and low-lying basins like the Kobar Sink.123
