Tropical Cyclone Alvaro was a tropical cyclone that traversed over Madagascar during New Year's Day. The first named storm of the 2023-24 South-West Indian Ocean cyclone season, Alvaro originated as a tropical disturbance at the Mozambique Channel. Being forecasted to develop into a moderate tropical storm, the disturbance was in a favorable environment for intensification. Tracking southeast, the system was upgraded into a tropical depression on December 31. It later intensified into a tropical storm, receiving the name Alvaro. Alvaro continued to move and intensify despite vertical wind shear. On January 1, Alvaro further intensified into a tropical cyclone before making landfall over Morombe District, Madagascar. It weakened back to a tropical depression after passing over the mountainous terrain of the island nation. Alvaro re-entered again to the Indian Ocean and intensified back into a moderate tropical storm. Shortly after reintensification, strong wind shear prevented any further development of the storm. Alvaro later transitioned into a post-tropical depression, being last noted on January 4.
