Current Weather Systems in Focus
A prominent low pressure zone remains positioned over the east-central Arabian Sea along with adjacent northeast parts. Another low pressure system is situated over the northern areas of Gangetic West Bengal and surrounding localities. These systems are driving widespread rain and thunderstorm possibilities across western, eastern, and northeastern parts of the country.
In the last day, ending at 8:30 AM today, several areas experienced substantial downpours. Places in Sub-Himalayan West Bengal and Sikkim saw heavy to very heavy rainfall ranging from 7 to 20 centimetres at certain spots. Similar intense showers hit isolated locations in Arunachal Pradesh, Bihar, and the Konkan-Goa region. Moderate heavy rain of 7 to 11 centimetres occurred in Saurashtra and Kutch, Jharkhand, plus Assam and Meghalaya.
Movement and Evolution of Low Pressure Areas
The low pressure that originated over northwest Jharkhand yesterday shifted north-northeast and reduced in strength. By evening on 31st October, it had become a regular low pressure over southwest Bihar and nearby Jharkhand. This morning, it continues over northern Gangetic West Bengal, with its circulation reaching up to 3.1 kilometres above sea level. Meteorologists expect it to travel further north-northeast and lose intensity within the coming 12 hours.
Meanwhile, the depression in the east-central Arabian Sea from the previous day has moved east-northeast and turned into a well-marked low pressure. It stays in the same area this morning, with circulation extending to 5.8 kilometres altitude. This system is projected to head towards the coasts of south Gujarat and north Maharashtra, crossing the northeast Arabian Sea, and diminish into a low pressure within the next day.
Additionally, a cyclonic circulation in the upper air persists over the south Myanmar coast and nearby north Andaman Sea, stretching through mid-tropospheric levels. This is likely to result in a fresh low pressure forming over the east-central Bay of Bengal in the next 24 hours. A new Western Disturbance will also start impacting the Western Himalayan region from the night of 3rd November.

Arunachal Pradesh growers should drain rice, field pea, and banana areas. For livestock, keep animals sheltered during heavy rain, provide balanced feed, store fodder safely. In fish ponds, create outlets with nets to manage overflow and prevent escape.
Against thunderstorms and gusty winds, support horticultural crops mechanically, stake vegetables and young fruit plants to prevent damage from lodging.
