MUMBAI – The India Meteorological Department said on Wednesday that a low pressure area has formed over Lakshadweep and the adjoining southeast and eastcentral Arabian Sea under the influence of an upper air cyclonic circulation. The low pressure area is likely to move northwestward and intensify into a depression over the central Arabian Sea during the next three-to-four days.
The Met department also said a cyclonic circulation lies over east Assam and the neighbourhood at lower tropospheric levels. Another cyclonic circulation lies over Sri Lanka and the neighbourhood area at lower and middle tropospheric levels, it said.
A low pressure area is an area in the atmosphere in which the air pressure is lower than the surrounding areas. A low pressure area is usually associated with bad weather and cyclones. A cyclonic circulation is an atmospheric wind flow at the upper levels associated with any low pressure system. The wind flow is counter-clockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere.
During the week, the weather bureau said heavy rainfall is very likely over parts of Tamil Nadu, Puducherry, and Karaikal. Similar weather conditions are also predicted over coastal Karnataka and Lakshadweep till Thursday, it said.
Parts of southern interior Karnataka might see heavy rainfall till Sunday, the weather agency said. It also expects heavy to very heavy rainfall over parts of Tamil Nadu from Saturday to Monday and over parts of Kerala and Mahe during the weekend.
In view of heavy rains in Tamil Nadu, the bureau advised farmers to drain excess water from rice nurseries and recently transplanted rice fields and to postpone harvesting of matured millet crops.
In northeast India, heavy rainfall is very likely over parts of Arunachal Pradesh, Assam, and Meghalaya till Friday and over parts of Nagaland, Manipur, Mizoram, and Tripura on Wednesday, the bureau said. Heavy rainfall is very likely over Konkan, Goa, and central Maharashtra till Saturday, it said.
Squally weather with wind speeds reaching 35 kilometres per hour to 45 km/h and gusting to 55 km/h is likely to prevail over the Maldives, Lakshadweep Comorin area, parts of the Arabian Sea, along and off Kerala, Karnataka, Goa, Maharashtra coasts, and the Gulf of Mannar from till Friday, the agency said. Such squally weather will also prevail over some parts of southwest Bay of Bengal and the adjoining southeast Bay of Bengal on Saturday. The bureau advised fishermen to not venture into these areas during the period.
The weather bureau said conditions are favourable for further withdrawal of the southwest monsoon from the remaining parts of Gujarat, Madhya Pradesh, Uttar Pradesh, some more parts of Maharashtra, and some parts of Bihar during the next two–three days. End
