Late on 19 January, Eloise made landfall in northern Madagascar as a moderate tropical storm, bringing with it heavy rainfall and flooding.

After moving southwestward across the Mozambique Channel for an additional 2 days, Eloise strengthened into a Category 1-equivalent cyclone, due to low wind shear and high sea surface temperatures.

Early on 23 January, Eloise peaked as a Category 2-equivalent tropical cyclone on the Saffir–Simpson scale as the center of the storm began to move ashore in Mozambique.

[11] On 14 January, a zone of disturbed weather formed over the central South Indian Ocean to the east of another system and gradually organized while moving westward.

[13] With the presence of persisting deep convection, the system eventually strengthened into Moderate Tropical Storm Eloise on 17 January.

Later that day, Eloise strengthened into a Category 1-equivalent tropical cyclone on the Saffir–Simpson Hurricane Scale (SSHWS), as it neared the coast of Mozambique, given the favorable conditions in the region.

[25] As the storm moved further inland, Eloise weakened rapidly, due to interaction with the rugged terrain and dry air.

[27] On 25 January, Eloise degenerated into a remnant low, and the MFR issued their final advisory on the system, with the storm dissipating soon afterward.

A meeting was organized on 19 January by the National Office for Risk and Disaster Management (BNGRC) to prepare for potential assessments and/or response.

[58] Furthermore, the rainfall affected 100,000 in Beira resettlement sites, which had been impacted by Cyclone Idai a year ago and Tropical Storm Chalane only a couple weeks before.

[59] Some of the worst-hit areas, such as the Buzi District, outside of Beira, were already submerged by days of heavy rains ahead of the cyclone's landfall, with floodwaters consuming fields and flowing through village streets.

[66] Due to persistent heavy rain, low-lying areas of Limpopo had seen mild flooding and debris which caused some roads to close.
