to the south.

Climate

Most precipitation comes in the winter months. Rainfall is as little as 3 mm along the coast. Rainfall is higher on the eastern slopes of the mountains, which intercept periodic moisture-bearing winds which create fog precipitation and occasional heavy rainstorms.

Flora

Vegetation includes mangrove swamps and salt marshes along the shore, sparse shrublands along the coast, and dry woodlands in stream valleys. Lusher woodlands and shrublands occur in areas with higher rainfall and mountain mists, and along mountain streams. Jebel Elba, a mountain lying near the coast in the border region contested between Egypt and Sudan, supports the most diverse plant life in the ecoregion.

Fauna

The mountains are home to the
