Meteorological History[ફેરફાર કરો]

Storm track

Under the influence of an upper air cyclonic circulation, a low pressure area formed over Andaman Sea on October 6.[૧] It slowly consolidated and was upgraded to a depression by the India Meteorological Department (IMD) on October 7. While over open waters, the depression continued to encounter favorable environment, and a tropical cyclone formation alert (TCFA) was issued by the Joint Typhoon Warning Center (JTWC), followed by IMD upgrading the storm into a deep depression.[૨][૩]

In the early hours of October 8, the JTWC started issuing its advisories for the system as it recorded tropical storm winds at the storm's centre.[૪] The IMD later reported that the deep depression made its first landfall over Long Island, Andaman and had reached cyclonic storm intensity, naming it Hudhud.[૫] After entering the Bay of Bengal, Hudhud continued to intensify the following day, and was upgraded to a severe cyclonic storm.

Early on October 10, the JTWC classified the storm a Category 1 tropical cyclone after its winds were estimated at 120 km/h (75 mph) and it formed a microwave eye feature, located in an environment favorable for further intensification with moderate wind shear.[૬] The IMD upgraded Hudhud to a very severe cyclonic storm later the same day, and the JTWC further upgraded the storm to a Category 2 tropical cyclone.[૭]

On October 11, Hudhud underwent rapid intensification and developed an eye at its center, resulting the JTWC to classify the storm as a Category 3 equivalent tropical cyclone.
