Crossing the Malay Peninsula into the Bay of Bengal on November 4, Gay became one of the most powerful systems on record in the basin, attaining an estimated pressure of 930 mbar (hPa; 27.46 inHg).
Initially, the depression tracked slowly towards the north-northwest before abruptly turning westward and slowing due to weak mid-level steering currents.
[6] Striking India on May 26, the storm brought wind gusts up to 130 km/h (80 mph) and torrential rains, amounting to 210 mm (8.3 in), which caused widespread damage.
[7] Communications across Orissa were severely disrupted as broadcast stations, government buildings, and hundreds of telephone poles were destroyed.
Over the following two days, convection associated with the low gradually organized and by June 9, satellite intensity estimates from the JTWC reached 55 km/h (35 mph).
Early on June 12, the cyclone was estimated to have attained tropical storm status based on a ship report near the center of 65 km/h (40 mph) sustained winds and a surface pressure of 998 mbar (hPa; 29.47 inHg).
Later that day, strong wind shear stemming from the anticyclone displaced convection from the tropical storm by more than 110 km (70 mi), prompting the final advisory from the JTWC.
Tracking west-northwest, the system intensified into a cyclonic storm later that day before making landfall in Andhra Pradesh, just north of Vishakhapatnam.
While over Maharashtra, the storm produced torrential rainfall, reaching 280 mm (11 in) in 24 hours in Bombay, which caused deadly flash flooding and mudslides.
[18] Most of the railway tracks in metropolitan Bombay were left underwater, paralyzing the city and forcing businesses to close for several days.
[25] On November 2, a tropical depression, later named Gay, developed in the Gulf of Thailand and favorable atmospheric conditions allowed the system to undergo rapid intensification.
[26] Crossing the Kra Isthmus in approximately six hours, the system emerged into the Bay of Bengal as a Category 1-equivalent cyclone and assumed a west-northwesterly track towards India.
Hours before making landfall in India, Gay attained its peak intensity as a Category 5-equivalent cyclone with winds estimated at 260 km/h (160 mph).
[29][30] Striking India as a powerful cyclone, Gay damaged or destroyed about 20,000 homes in Andhra Pradesh, leaving 100,000 people homeless.
