Sub: Severe Cyclonic storm ‘LEHAR’ over Southeast Bay of Bengal: Cyclone
Alert for Andhra Pradesh coast (Yellow Message )
--
A low pressure area formed over the South China Sea on 18 November. It slowly drifted westwards and crossed over the Malay Peninsula into the Bay of Bengal on November 22. There, it developed a well-defined low-level circulation center (LLCC). The Joint Typhoon Warning Center (JTWC) issued a Tropical cyclone formation alert (TCFA) on the system, assuming that it would intensify further as it moves into warmer sections of the Bay of Bengal. Tracking westward at over 08 knots (15 km/h; 9.2 mph), the system gradually intensified over the next 24 hours. Early on November 23, the JTWC classified the system as a Tropical Storm, designating it with 05B. A couple of hours later, the India Meteorological Department (IMD) started tracking this system as a Depression. It was initially assigned the code BOB 07.] Early the next day, the IMD reported that BOB 07 had reached deep depression status,and immediately afterwards, they upgraded BOB 07 into a cyclonic storm, naming it Lehar. Being located in an area of moderate vertical wind shear of around 15 knots (28 km/h; 17 mph), convection gradually consolidated around the LLCC, though being slightly displaced towards the northwest

Very Severe Cyclonic Storm Lehar
(Hindustani: meaning "wave") is an active tropical cyclone in the Bay
of Bengal that is forecast to hit the east coast of India, close to Kakinada,
Andhra Pradesh with winds of over 100 knots (190 km/h; 120 mph). The origins of
Lehar can be tracked back to an area of low pressure that formed in the Pacific
ocean on 18 November. The system slowly drifted westwards and entered the Bay
of Bengal, where it quickly intensified into a cyclonic storm. The Cyclone is
expected to hit the coastal regions of Andhra Pradesh on November 28.These
regions have faced strong winds from Cyclones Phailin and heavy rainfall from
Helen, the past month
