context_page_description: The 2001 India cyclone was the third strongest tropical cyclone, in terms of barometric pressure, to form in the Arabian Sea on record; only Cyclones Gonu in 2007 and Kyarr in 2019 were stronger. The storm originated from a tropical disturbance that formed east of Somalia on May 18. Over the following few days, the system gradually organized into a tropical depression. Tracking eastward, towards the coastline of southwestern India, the storm slowly intensified. Shortly before reaching shore, the system turned north and later west, away from land. After taking this turn, the storm intensified into a very severe cyclonic storm, attaining its peak intensity on May 24 with winds of 215 km/h and a barometric pressure of 932 mbar. At the time, this ranked the cyclone as the strongest known storm in the Arabian Sea.
  After stalling several hundred kilometres offshore, the storm weakened over cooler waters that it had upwelled. By May 27, the system weakened to a cyclonic storm and by this time was approaching the northwestern coastline of India, near Gujarat. The following day, the storm made landfall in the Saurashtra region as a deep depression with winds of 55 km/h.
context_section_description: The origins of the 2001 India cyclone can be traced to a tropical disturbance over the Arabian Sea on May 18. The following day, the system was determined to be relatively stationary near the island of Socotra. Although deep convection was associated with the disturbance, there was no evidence of a low-level circulation. By May 20, the disturbance slowly moved towards the southeast in response to an upper-level trough over India. The overall structure gradually improved as good outflow developed. A mid-level circulation finally developed late on May 21, prompting the Joint Typhoon Warning Center (JTWC) to issue a Tropical Cyclone Formation Alert. Several hours later, they began monitoring the system as a tropical depression with the identifier 01A; however, operational advisories were not issued until the cyclone was estimated to have attained tropical storm intensity. By the morning of May 22, the India Meteorological Department (IMD) also took notice of the system.
  Situated in a region favoring tropical cyclone development about 650 km (400 mi) southwest of Mumbai, India, the storm rapidly developed. By the afternoon of May 22, the JTWC estimated that 01A attained winds of 120 km/h (75 mph), equivalent to a Category 1 hurricane on the Saffir–Simpson Hurricane Scale. Additionally, a 22 km (14 mi) wide eye developed within the center of circulation during this intensification phase. Throughout most of May 22, the strengthening slowed considerably as it paralleled the southwestern coast of India. Initially, it was feared that the storm would move inland as a powerful cyclone; however, a ridge over the northern Arabian Sea caused the storm to turn westward, back over open water. Once further away from land, the cyclone resumed intensification, becoming a rare, Category 3 equivalent storm by the morning of May 24. Later that morning, 01A attained its peak intensity with winds of 205 km/h (125 mph), according to the JTWC. However, the IMD considered the storm to be slightly stronger, estimating that it attained winds of 215 km/h (130 mph) by three-minute sustained winds along with a barometric pressure of 932 mbar (hPa; 27.52 inHg).
  At the time of peak intensity, the cyclone displayed a well-defined eye and excellent outflow. Although a powerful storm, it quickly weakened as conditions became hostile for tropical cyclone development. Strong wind shear tore convection away from the cyclone and caused it to become disorganized. Within 48 hours, the system had degraded to a tropical storm and was situated roughly 555 km (345 mi) west-southwest of Mumbai. The weakening trend lessened shortly thereafter but still continued. Operationally, the JTWC issued their final advisory on the cyclone on May 28 as it weakened to a tropical depression over open waters. The once powerful cyclone, now devoid of all convection, tracked towards the northwestern coast of India. During the afternoon of May 29, the cyclone rapidly regenerated as it made landfall in Gujarat. The JTWC estimated that it crossed the coastline with winds of 100 km/h (65 mph). Not long after moving overland, the system rapidly weakened and dissipated over India within several hours.
