The India Meteorological Department (IMD) has issued a heavy rainfall alert for several states — including Bihar, West Bengal, Sikkim, and Madhya Pradesh — as weather systems linked to Cyclone Montha and a depression over the east-central Arabian Sea continue to influence India’s climate pattern.
According to the IMD, the remnants of Cyclone Montha, which made landfall earlier this week on India’s east coast, are now interacting with a fresh low-pressure area forming over the Arabian Sea. This dual system is expected to bring widespread rains, thunderstorms, and gusty winds across eastern, central, and parts of northern India over the next few days.
States Under Alert
Bihar: Heavy to very heavy rain is forecast in the northern and central districts, raising concerns over waterlogging and minor flooding in low-lying areas.
West Bengal & Sikkim: Moderate to heavy rainfall is expected, especially in the Sub-Himalayan and Gangetic regions, potentially disrupting transport and agricultural activities.
Madhya Pradesh: The IMD has cautioned about thunderstorms and lightning in the eastern and central parts, with isolated heavy downpours likely.
Cyclone Montha’s Lingering Impact
Cyclone Montha, which struck the east coast earlier this week, has already caused significant rainfall and flooding in parts of Andhra Pradesh and Odisha. Its residual moisture and interaction with western weather systems are now triggering renewed rainfall activity further inland.
Meteorologists note that the combined weather influence is typical during post-cyclonic transitions, where remnants of a cyclone merge with other low-pressure systems, extending the impact zone.
Advisory for Citizens
The IMD has advised residents in the affected states to:
Stay updated with local weather bulletins.
Avoid travel through waterlogged or low-lying areas.
Farmers are advised to delay harvesting operations and protect stored crops from excessive moisture.
Fishermen are urged to avoid venturing into the Arabian Sea and Bay of Bengal coasts until conditions normalize.
Disaster management teams in Bihar, West Bengal, and Madhya Pradesh have been put on alert to respond to any emergency arising from flash floods or infrastructure disruptions.
Forecast Outlook
According to the IMD’s extended forecast, rainfall intensity is likely to reduce gradually after 72 hours as the depression weakens. However, localized heavy showers may continue in parts of eastern India and the Himalayan foothills.
This weather pattern highlights the increasing unpredictability of India’s post-monsoon climate, further linked to climate change and warming ocean conditions.
FAQs
1. Which states are under IMD’s heavy rainfall alert?
Bihar, West Bengal, Sikkim, and Madhya Pradesh are under active warnings due to Cyclone Montha’s remnants and the Arabian Sea depression.
2. What caused the widespread rainfall?
The combined influence of Cyclone Montha’s leftover system and a new depression over the east-central Arabian Sea.
3. When will the rain intensity decrease?
IMD predicts that the rainfall will start to subside gradually after three days as the systems weaken.
4. Are coastal areas at risk?
Yes, moderate coastal winds and rough sea conditions persist, and fishermen are advised against venturing out.
