Twin Cyclones Judy and Kevin Hammer Vanuatu in Rare Back-to-Back Strike
Severe Tropical Cyclone Judy struck Vanuatu on 1 March 2023, becoming the first of two powerful cyclones to hit the island nation within days. Named by the Fiji Meteorological Service, Judy intensified rapidly over the South Pacific and reached Category 4 severity on the FMS scale before crossing the region. The cyclone was followed by Severe Tropical Cyclone Kevin and a magnitude 6.5 earthquake, creating an unprecedented disaster sequence for Vanuatu. Judy peaked at 185 km/h (10-min sustained) and 940 hPa, according to FMS records.
Judy Rapidly Intensifies En Route to Vanuatu
Judy formed on 24 February 2023 as a tropical depression near 14.4°S and 184.4°E, east of the Solomon Islands region. The system strengthened steadily while moving through the western South Pacific, becoming a tropical cyclone on 27 February.
The FMS upgraded Judy to Category 1 on 28 February, then to Severe Tropical Cyclone status on 1 March as rapid intensification occurred. At peak intensity near 19.8°S and 169.7°E, FMS data recorded 10-minute sustained winds of 185 km/h and a central pressure of 940 hPa.
Under the United States-based Saffir-Simpson Hurricane Wind Scale, Judy’s peak intensity was equivalent to a Category 3 hurricane, with one-minute sustained winds estimated near 195 km/h. The difference reflects the separate wind averaging methods used by regional meteorological agencies.
Judy approached Vanuatu from the west and affected the country’s central islands, including Efate, where the capital Port Vila is located. Forecast centers tracked the storm closely as warnings were issued for destructive winds, heavy rainfall, and coastal hazards.
Judy and Kevin Strike Vanuatu in 48-Hour FMS Cat 4 Assault
Judy crossed Vanuatu on 1 March 2023, bringing severe winds, flooding, and widespread damage across several islands. Strong winds damaged homes, schools, public facilities, roads, and communication networks, while heavy rainfall caused localized flooding.
The storm’s impact was followed by Severe Tropical Cyclone Kevin, which struck Vanuatu on 3 March 2023, only two days after Judy. The back-to-back cyclones affected communities that were still responding to Judy’s damage, creating major challenges for emergency teams and residents.
A magnitude 6.5 earthquake, centred about 30 km west of Espiritu Santo, struck on 3 March, followed by a 5.4 magnitude aftershock. The combination of two severe cyclones and seismic activity disrupted transportation, electricity services, water supplies, and recovery operations.
Post-disaster assessments estimated that the combined effects of Cyclones Judy and Kevin caused approximately US$433 million in damage and losses across Vanuatu. Agriculture, housing, tourism, infrastructure, and public services were among the sectors affected.
Australia, New Zealand, and regional partners provided humanitarian assistance following the disasters, including support for relief operations and recovery efforts. The events became one of Vanuatu’s most significant disaster sequences in recent years.
Judy Weakens to Subtropical Storm Over Open Pacific
After passing Vanuatu, Judy moved southeastward across the South Pacific and gradually weakened. The cyclone declined from Category 3-equivalent intensity on 2 March as it moved away from the islands and entered cooler ocean conditions.
By 3 March, Judy had weakened into a tropical storm with winds near 100 km/h. The system continued losing tropical characteristics and transitioned into a subtropical system on 4 March.
Judy remained over open waters as it weakened further, with its circulation becoming less organized. The storm dissipated on 5 March 2023 near 30.3°S and 205.0°E, ending a lifecycle that lasted from 24 February to 5 March.
The final best-track records from international cyclone databases show Judy’s peak intensity on 1 March 2023, with a minimum central pressure of 940 hPa and maximum recorded winds of 55.6 m/s in the dataset’s wind conversion records.
Vanuatu Faces $433M in Damages After Twin Cyclone Disaster
The 2023 cyclone sequence produced extensive reconstruction needs for Vanuatu after Judy and Kevin damaged critical infrastructure and affected communities across the country.
Recovery efforts focused on restoring essential services, repairing damaged buildings, supporting affected households, and rebuilding agricultural production. The combined disaster impacts placed significant pressure on national resources and emergency response systems.
Cyclone Judy remains notable in South Pacific meteorological records because of its rapid intensification, severe impact on Vanuatu, and its close timing with Cyclone Kevin. The storm developed from a tropical depression on 24 February, reached peak strength on 1 March near Vanuatu, weakened into a subtropical system on 4 March, and dissipated on 5 March 2023.
