On February 2, the Regional Specialized Meteorological Centre for the southwest Indian Ocean, Météo-France, and the Joint Typhoon Warning Center (JTWC) began monitoring a tropical disturbance located in the western portion of Météo-France's area of responsibility. However, it was not operationally classified as a disturbance for another two days. Traveling generally towards the southwest, the disturbance slowly strengthened. At 0300 UTC on February 4, the JTWC issued a Tropical Cyclone Formation Alert for the system as deep convection and outer bands developed around the center. Located within a narrow area of low to moderate wind shear, the system traveled towards the west-southwest at 15 km/h (9 mph). Shortly after, Météo-France began issuing advisories on Tropical Disturbance 10 while it was located about 1,020 km (635 mi) east-southeast of Diego Garcia. A buoy located just to the south of the small circulation recording decreasing atmospheric pressure, having lowered by 4 hPa (mbar) in the past 24 hours.
With weak steering currents provided by an area of high pressure to the north, the disturbance slowly moved towards the east-southeast. At 1500 UTC, the JTWC began issuing advisories on the disturbance which they designated as Tropical Cyclone 16S. With high oceanic heat content, low wind shear, and good divergence aloft, significant strengthening was likely. Early the next day, Météo-France upgraded the disturbance to a tropical depression as winds increased to 55 km/h (35 mph ). However, in the post-season analysis, Météo-France determined that the system had become a depression about 12 hours earlier and was already a moderate tropical storm by the time of the operation upgrade. At 0600 UTC, Météo-France classified the depression as a moderate tropical storm and was given the name Hondo; a name submitted to the World Meteorological Organization by Zimbabwe. It was later determined that Hondo was already a severe tropical storm by the time it was named operationally.
Hondo continued to quickly strengthen, becoming a tropical cyclone, the equivalent of a Category 1 hurricane on the Saffir-Simpson Hurricane Scale, that same day. After maintaining its through the early hours of February 6, a pinhole eye began to develop, signifying that Hondo was beginning to undergo rapid intensification. During this intensification phase, the storm became nearly stationary again due to a weakness in the ridge which was previously steering the cyclone towards the east. Later that day, Hondo was upgraded to an intense tropical cyclone with winds of 175 km/h (110 mph ). After becoming an intense tropical cyclone, wind shear began to increase, causing the eye to become slightly disorganized, temporarily slowed the intensification. Later in the day, the eye became better defined, allowing Hondo to intensify further. Operationally, Hondo was upgraded to a very intense tropical cyclone with winds of 220 km/h (140 mph ) with a minimum pressure of 906 hPa (mbar). However, after reanalysis, it was found that Hondo never intensified beyond intense tropical cyclone status and winds peaked at 215 km/h (130 mph ) with a minimum pressure of 915 hPa (mbar).
Around the same time that Météo-France assessed Hondo to have peaked, the JTWC reported that the storm had attained winds of 230 km/h (145 mph ), equivalent to a strong Category 4 hurricane. Shortly after reaching peak intensity, the cloud tops around the eye began to warm, meaning that the storm was beginning to weaken. Hondo also turned towards the southwest and kept a steady pace as two subtropical highs began influencing its movement. The storm continued to weaken as cloud tops warmed but remained an intense tropical cyclone as its eye was still well-defined. Hondo briefly re-intensified later on February 8 despite the structure of the storm deteriorating. The cyclone maintained intense tropical cyclone status through February 10 due to the formation of a large eye which helped maintain the storms structure. Hondo gradually began to weaken due to a combination of decreasing sea surface temperatures and increasing forward motion. On February 10, Hondo started a gradual curving path due to a trough located to the south and strengthening high pressure systems to the north. At 0600 UTC, the storm was downgraded to a tropical cyclone as winds decreased to 155 km/h (100 mph).
Continued weakened led to the storm being downgraded to a severe tropical storm early on February 11 as it tracked towards the southeast. After spending several hours over cold waters, most of the convection associated with Hondo dissipated due to the lack of energy and the storm was further downgraded to a moderate tropical storm. Later that day, no convection remained around the storm as it weakened to a tropical depression. The JTWC issued their final advisory on February 12 as the storm showed no signs of convective activity. Hondo degenerated into a remnant-low pressure area as Météo-France issued their final advisory at 1200 UTC. For the next week, the remnant low traveled in a general west-northwestward direction with little or no development. On February 20, about 2,780 km (1,725 mi) northeast of where the final advisories were issued, the low began to develop weak convection around the northern edge of the center of circulation.
On February 21, Météo-France began to issue advisories on Tropical Disturbance Ex-Hondo which presented a well-defined circulation. Later that day, deep convection redeveloped around the center as the low entered an area favorable for development. At 0830 UTC, the JTWC issued a Tropical Cyclone Formation Alert, stating that Hondo was likely to regenerate into a tropical cyclone. Later that day, Hondo became almost stationary and was upgraded to a tropical depression as it continued to develop. The next day, Hondo was downgraded to a tropical disturbance as wind shear constrained convective development and caused the system to weaken. However, early on February 23, the JTWC began issuing advisories on Hondo as they estimated winds to have reached 65 km/h (40 mph) once more. At 0600 UTC, Hondo attained winds of 95 km/h (60 mph ) near Mauritius and Réunion. Due to the proximity to the islands, convection associated with the storm became disorganized and it began to weaken. The JTWC issued their final advisory early on February 24 as the system significantly weakened, with the center devoid of convection. Météo-France issued their final advisory several hours later. The remnants of Hondo persisted for another five days, executing a counterclockwise loop before dissipating on February 29.
