Cyclone Belal is a currently active storm that is currently threatening Réunion and Mauritius. The second named storm of the 2023–24 South-West Indian Ocean cyclone season, Belal originated from a monsoon trough.

Meteorological History

On 11 January, the MFR marked a zone of disturbed weather, citing the conducive conditions induced by the MJO and an equatorial Rossby wave. The monsoon trough north-northeast of Madagascar had intensified several days prior, as convergence transferred moisture aloft.[1] Concentration of convection near the center increased, particularly in the western section, as the system steered south.[2] By the next day, the JTWC issued a Tropical Cyclone Formation Alert (TCFA) on the potential disturbance, since it was in an environment of very warm sea surface temperatures, high ocean heat content, low vertical shear, and excellent outflow.[3] At 12:00 UTC, the MFR categorized the system as a tropical depression. Additionally, microwave imagery indicated an eye in the lower-layer,[4] and the JTWC began issuing advisories on the system as a tropical cyclone.[5] By 13 January, it intensified to a moderate tropical storm, prompting the MMS to name it Belal.[6] Intense lightning activity within the center further signaled a period of rapid intensification, leading to Belal becoming the second severe tropical storm of the season.[7]

Preparations and Impact

As the system developed, the MFR issued a yellow cyclone pre-alert for Réunion,[8] which would be upgraded to an orange cyclone alert on 15:00 UTC the next day.[9] On 13 January, the MMS issued a class I cyclone warning for Mauritius.[10]
