Cyclone threat for north Konkan, south Gujarat Vinson Kurian Thiruvananthapuram, Nov. 10 India Meteorological Department (IMD) has issued a tropical cyclone formation alert in the Arabian Sea as Monday’s depression intensified into deep depression, a notch below cyclone status. The IMD had early this morning elevated an existing well-marked ‘low’ over southeast and adjoining east-central Arabian Sea to a depression. MOVES NORTH The depression later moved northwards, intensified into a deep depression and lay centred about 470 km west of Mangalore; 470 km southwest of Goa; and 700 km south-southwest of Mumbai around 3 p.m. on Tuesday. What seems to have fuelled the intensification is its movement into open east-central Arabian Sea that is warmer than along the coast-affording it more stay on waters - and less wind shear. Satellite imagery indicated organisation of convection leading to curved band features. Associated broken intense to very intense convection lay over east-central and adjoining southeast Arabian Sea and off Karnataka, Goa and Maharashtra coasts and over Lakshadweep. The prospective cyclonic storm is expected to move in a northerly direction and then north-northeastwards to cross south Gujarat and north Konkan coast between Mahuva and Dahanu by early hours of Thursday, the IMD said. Widespread rainfall with isolated heavy to very heavy falls and isolated extremely heavy falls exceeding 25 cm has been forecast over Konkan, Goa and Madhya Maharashtra during the next two days. Widespread rainfall with isolated heavy falls is also likely over coastal Karnataka during the next 24 hours. Fairly widespread to widespread rain with heavy to very heavy falls and isolated extremely heavy falls exceeding 25 cm is likely over south Gujarat from Wednesday onwards. A warning valid for the next two days said that isolated heavy to very heavy rainfall is likely over coastal Karnataka during next 24 hours. Heavy to very heavy rainfall with isolated extremely heavy falls is likely over south Gujarat on Wednesday. Squally wind reaching 55 to 65 km/hr in speed gusting to 75 km/hr are likely along and off Kerala, Karnataka, Goa and Maharashtra coasts during the next two days and over Lakshadweep area and Kerala coasts during the next 24 hours. Squally wind speed reaching 55 to 65 km/hr gusting to 75 km/hr are likely to commence along and off south Gujarat coast from Wednesday afternoon. Sea condition will be very rough over Lakshadweep area and along and off Kerala, Karnataka, Goa and Maharashtra coasts. Fishermen are advised not to venture out.
