Several parts of India will experience rainfall on Saturday, October 31, as two weather systems influence the country. The India Meteorological Department is tracking the remnants of Cyclone Arnab over central India and a fresh low-pressure area over the Andaman Sea. These systems could bring rain across many states soon.
Several parts of India are likely to experience rainfall on Saturday, October 31, as two weather systems influence conditions across the country, with a fresh low-pressure area over the Andaman Sea expected to intensify into a depression and move towards the Andhra Pradesh coast.
The India Meteorological Department (IMD) is tracking the remnants of Cyclone Arnab over central India and a developing weather system over the Bay of Bengal, both of which could trigger rainfall across multiple states over the weekend.
The remnants of Cyclone Arnab, which had earlier weakened from a Very Severe Cyclonic Storm, continue to influence weather conditions over central India.
According to the IMD, the well-marked low-pressure area over central Chhattisgarh and adjoining Odisha weakened further into a low-pressure area and lay over north Chhattisgarh and adjoining east Madhya Pradesh at 8:30 am on Friday.
The system is expected to continue weakening, although its associated circulation and atmospheric troughs could sustain rainfall over parts of central and eastern India.
FRESH LOW-PRESSURE SYSTEM BREWING OVER BAY OF BENGAL
The bigger weather development is unfolding over the South Andaman Sea, where a fresh low-pressure area has been gathering strength.
The system moved west-northwestwards and lay over the South Andaman Sea and adjoining Andaman and Nicobar Islands on Friday morning.
The IMD has indicated that it is very likely to concentrate into a depression over the southeast Bay of Bengal and adjoining Andaman and Nicobar Islands around October 31.
It is then expected to move west-northwestwards towards the Andhra Pradesh coast over the subsequent two days.
This system could bring rainfall across parts of southern and eastern India as it strengthens and approaches the coastline.
MULTIPLE WEATHER SYSTEMS INFLUENCING INDIA
Apart from these two major systems, several atmospheric circulations and troughs are also influencing weather conditions.
A cyclonic circulation over north Punjab, another over South Gujarat and one over Assam are contributing to the evolving weather pattern. An additional trough extending from the east-central Arabian Sea towards the circulation over central India could also influence rainfall activity.
Together, these systems are creating conditions favourable for rain across parts of central, eastern and southern India.
The developing depression over the Bay of Bengal will remain the key weather system to watch over the next 48 hours, particularly because of its projected movement towards the Andhra Pradesh coast.
Its eventual intensity, movement and proximity to the coastline will determine the distribution and intensity of rainfall across southern and eastern India.
