The Afar Triple Junction is located along a divergent plate boundary dividing the Nubian, Somali, and Arabian plates. This area is considered a present-day example of continental rifting leading to seafloor spreading and producing an oceanic basin. Here, the Red Sea Rift meets the Aden Ridge and the East African Rift. The latter extends a total of 6,500 kilometers (4,000 mi) from the Afar Triangle to Mozambique.

Cyclonic Storm Sagar was the strongest tropical cyclone to make landfall in Somalia and Somaliland in recorded history until Gati in 2020, and the first named cyclone of the 2018 North Indian Ocean cyclone season. Forming on May 16 east of the Guardafui Channel, Sagar intensified into a cyclonic storm on the next day, as it gradually organized. The storm turned to the west-southwest and traversed the entirety of the Gulf of Aden, making landfall over Somaliland on May 19, farther west than any other storm on record in the North Indian Ocean. Sagar weakened into a remnant low on May 20.
