Cyclone Biparjoy
Extremely Severe Cyclonic Storm Biparjoy (/ˌbɪpərˈdʒɔɪ/) was a powerful and erratic tropical cyclone that formed over the east-central Arabian Sea. The third depression and the second cyclonic storm of the 2023 North Indian Ocean cyclone season, Biparjoy originated from a depression that was first noted by the India Meteorological Department (IMD) on 6 June, before intensifying into a cyclonic storm. The cyclone steadily weakened due to deep flaring convection. Biparjoy accelerated northeastward, strengthening to a Category 3-equivalent tropical cyclone and an extremely severe cyclonic storm. The cyclone made landfall in Naliya, India on June 16. Biparjoy was downgraded to a depression, and further into a well-marked low-pressure area late on June 19.
On June 12, the IMD issued alerts to local authorities in Gujarat, encouraging them to prepare for possible evacuations. Residents in coastal areas were warned to stay indoors as the storm approached. Gujarat's government responded by dispatching national and state disaster response teams to the affected areas. More than 1,50,000 people were evacuated. At least 23 people were injured as well as 4,600 villages were affected by power outages in India. A total of 12 people were confirmed to have been killed in India.
On 1 June, the India Meteorological Department (IMD) began monitoring the potential for a formation of a cyclonic circulation in the Arabian Sea. A cyclonic circulation formed over the Arabian Sea on June 5. On the same day, a low-pressure area formed as a result of the cyclonic circulation. The following day, it significantly intensified into a depression. The Joint Typhoon Warning Center (JTWC) issued a Tropical Cyclone Formation Alert on the system as a result, marking it as Invest 92A. The IMD upgraded the depression to a deep depression, and subsequently to a cyclonic storm, assigning it the name Biparjoy. The JTWC subsequently initiated advisories on the system and classified it as Tropical Cyclone 02A. Six hours later as its convection evolved into a central dense overcast (CDO) with a nascent eye, Biparjoy steadily strengthened, gaining Category 1-equivalent winds of 130 km/h (80 mph).
By 00:00 UTC on 7 June, the IMD upgraded the system to a severe cyclonic storm with 3-minute sustained winds of 100 km/h (65 mph). Biparjoy cloud tops warmed and the convective burst collapsed, resulting in an upper-level outflow from the storm and pushing it back towards its system core. Biparjoy was upgraded to a very severe cyclonic storm at 06:00 UTC, at which point the system became a Category 2-equivalent tropical cyclone on the Saffir–Simpson hurricane wind scale (SSHWS). The cyclone was sheared due to moderate easterly vertical wind shear, with the deep convection displaced from the low-level circulation center. The cyclone steadily weakened due to deep flaring convection. Biparjoy unexpectedly rapidly intensified and became a Category 3-equivalent cyclone on 11 June.
Biparjoy reached its peak intensity as an extremely severe cyclonic storm, with maximum 3-minute sustained winds of 165 km/h (105 mph). The shear decreased and convective organization and areal extent increased. Banding features became increasingly evident in satellite images along the southern periphery. Biparjoy gradually weakened with convective banding over the northern semicircle. The structure of the cyclone quickly deteriorated as convection became asymmetric. Biparjoy made landfall on June 16 near Naliya, India, with sustained winds of 95 km/h (60 mph). Shortly after the landfall, the JTWC discontinued warnings on the system. The cyclone weakened into a depression. The depression was later marked as a well-marked low-pressure area by the IMD on June 19, prompting the discontinuation of advisories on the system.
Biparjoy broke the record for the highest accumulated cyclone energy of any North Indian Ocean cyclone, passing Cyclone Kyarr's 2019 mark.
To lessen the potential effects of Cyclone Biparjoy, authorities, and stakeholders, particularly the Provincial Disaster Management Authority (PDMA), have taken proactive preparations. Meetings with stakeholders have been held to create coordination and readiness plans. Relevant authorities have been tasked by the PDMA with identifying high-risk areas, launching public awareness campaigns, creating evacuation plans, and ensuring the safe evacuation of locals from exposed coastal areas. Authorities removed billboards and signboards across Karachi and advised a voluntary evacuation of coastal residential neighborhoods in Karachi.
A total of 81,000 individuals were evacuated from the south-eastern coast, and authorities have established 75 relief camps at schools to assist. The weather office predicted heavy rains and strong winds for the districts of Karachi, Hyderabad, Badin, Tando Allahyar, Umerkot, Mirpurkhas, Tharparkar, Mithi Shaheed Benazirabad, and Sanghar. The areas likely to be affected include Thatta, Badin, Sajawal, Tharparkar, Karachi, Mirpurkhas, Umerkot, Hyderabad, Tando Allah Yar Khan, and Tando Mohammad Khan districts. It is estimated that approximately 9,000 households (approx. 55,000 people) are at risk of direct impact. Widespread wind-dust, thunderstorm activity, and heavy rainfall are expected mainly in districts of Sindh.
