The 1998 Gujarat cyclone (Joint Typhoon Warning Center designation: 03A; India Meteorological Department designation: ARB 02) was a deadly tropical cyclone that killed at least 10,000 people in India. ==Meteorological history==
On June 1, an area of low pressure developed over the Laccadive Islands. Two days later, the JTWC issued a TCFA for the system as it became better organized. Early on June 4, the JTWC issued its first advisory on Tropical Cyclone 03A. Around the same time, the IMD began monitoring the system as Depression ARB 02. Shortly after, the depression was upgraded to a deep depression and further strengthened into a cyclonic storm the following day. The small storm moved slowly towards the west and weakened as wind shear began to increase. The storm weakened below tropical storm intensity later that day and the initial final advisory was issued. However, the system redeveloped and advisories resumed the next day. The storm gradually intensified as it moved towards the northwest.〔 Dvorak satellite intensity estimates on June 6 reached T4.0, corresponding to an intensity of 120 km/h (75 mph). The IMD also marked the increase in intensity, upgrading ARB 02 to a severe cyclonic storm.〔 Around this time, the storm began to turn towards the north and accelerate due to an approaching mid-level trough. As the storm neared the Indian coastline, an eye developed and the storm strengthened into the equivalent of a major hurricane with winds reaching 185 km/h (115 mph).〔 The IMD assessed the storm to be a very severe cyclonic storm at this time, with winds up to 165 km/h (105 mph) and a barometric pressure of 958 mbar (hPa).〔 After slightly weakening early on June 9,〔 03A re-strengthened, attaining its peak intensity with winds of 195 km/h (120 mph).〔 Then it made landfall near Porbandar in the Indian state of Gujarat〔 between 0100 and 0200 UTC.〔 The storm weakened following landfall and the JTWC issued their final advisory later that day.〔 The IMD continued to monitor ARB 02 until June 10, by which time it had weakened to a depression before dissipating.〔
