The India Meteorological Department on Monday informed that certain parts of Tamil Nadu and Andhra Pradesh are likely to experience extremely heavy rainfall from November 10 to 11. It may inundate roads and low-lying areas and cause riverine flooding in some catchment areas.
A cyclonic circulation lies over the southeast Bay of Bengal and the adjoining south Andaman Sea extending up to middle tropospheric levels under the influence of which a low-pressure area is likely to be formed in the next 24 hours over the Southeast Bay of Bengal and neighbourhood. This is likely to move west-northwestwards, concentrate into a depression, and reach the north Tamil Nadu coast by November 11.
"Under its influence, isolated heavy to very heavy rainfall is likely over Tamil Nadu on November 8 and 9 and heavy to very heavy rain at few places with isolated extremely heavy falls are very likely on November 10 and 11. Heavy to very heavy rain with extremely heavy falls at isolated places are also likely over south coastal Andhra Pradesh during the same period," the IMD said. The IMD further warned fishermen not to venture into vulnerable areas.
Stormy weather with wind up to 60 kmph is predicted over southwest and adjoining west-central Bay of Bengal and along and off south Andhra Pradesh-Tamil Nadu coasts and Gulf of Mannar for the next four days. Similar conditions are also likely over Southeast Bay of Bengal in the next two days.
The IMD further warned of localised flooding of roads, inundation and waterlogging in low-lying areas. Urban areas may also experience underpass closures. There is also the possibility of localised landslides, as well as minor damage to kutcha roads, vulnerable structures and to horticulture and standing crops in some areas.
A depression over east-central Arabian Sea has moved west-northwestwards in the last six hours with a speed of 8 kmph. It now lays centred over east-central Arabian Sea about 840 km west-southwest of Mumbai and 800 km west-southwest of Panjim. It is likely to move nearly westwards and weaken into a well-marked low-pressure area by Tuesday morning.
