Tropical Cyclone Idai is shown approaching landfall in Mozambique late Thursday. Cyclone Eline, which hit the country in February 2000 when it was already devastated by its worst floods in three decades, killed 350 people and made 650,000 homeless across Southern Africa.
The storm is expected to make landfall Thursday night near Beira, Mozambique's fourth largest city, with 530,000 residents.

As Tropical Cyclone Idai comes back ashore in southern Africa, flooding from the system that became the storm has killed 122 people in Mozambique and Malawi, making it the deadliest weather disaster of 2019.
According to the Saffir-Simpson scale Cyclone Idai is now and extremely risky category 4 storm and has explosively intensified in the past 8 hours which is expected to make landfall by tomorrow. Locally damaging winds will also be possible in for Zimbabwe.
