A Wet Spell Ahead Odisha Braces for Thunderstorms and Possible Low-Pressure Formation

As October progresses, Odisha may continue to stay under the influence of active weather systems. Recent reports indicate that thunderstorms, gusty winds, and heavy rains are likely across many districts over the coming days, and a fresh cyclonic circulation or low-pressure area might emerge over the Bay of Bengal – potentially delaying the usual monsoon withdrawal.

What the Forecasts Are Saying

Thunderstorms and Rain in the Next Few Days

The India Meteorological Department (IMD) expects thunderstorms, lightning, and moderate rainfall in both coastal and interior parts of Odisha over the next 3 to 4 days.

Districts likely to see such activity include Sundargarh, Jharsuguda, Bargarh, Sambalpur, Deogarh, Angul, Dhenkanal, Keonjhar, Mayurbhanj, Balasore, Bhadrak, Jajpur, Kendrapara, Cuttack, Jagatsinghpur, Puri, Khordha, Nayagarh, Ganjam, and Gajapati.

Warnings have been issued under a Yellow Alert (i.e. “Be Aware”) for many districts, signaling that thunderstorms with lightning and gusty winds of 30-40 km/h may occur at one or two places in those districts

Even on days when thunderstorms may not be widespread, light to moderate rain or thundershowers are still expected in many places across Odisha.

Possible Low Pressure / Cyclonic Circulation Over Bay of Bengal

Several forecasts suggest the formation of a fresh cyclonic circulation or low-pressure area (LoPAR) over the northern Bay of Bengal in the second half of the week.

The IMD’s models (IMD-GFS, NCEP-GFS, Bharat Forecast System, NCUM, etc.) hint at this low forming around October 9 to October 10.

The formation of this system could delay the withdrawal of the southwest monsoon from Odisha, which typically occurs between October 10 and 15.

A trough (a zone of relatively lower pressure) remains active from north coastal Odisha through interior Odisha to Telangana and South Chhattisgarh, which aids in moisture convergence, fueling thunderstorm activity.

Also, an upper air cyclonic circulation over northeast Jharkhand and its adjoining areas is contributing to instability in the atmosphere.

Possible Impacts & What to Watch Out For

1. Delay in Monsoon Withdrawal
   If the low-pressure system intensifies and lingers, the withdrawal of the southwest monsoon from Odisha could be postponed beyond its usual mid-October timeframe.
2. Localized Flooding, Waterlogging
   High intensity rainfall over short durations, especially in low-lying and urban areas, may lead to waterlogging, poor drainage, localized flooding, and disruption in movement.
3. Disruption due to Thunderstorms
   Lightning, gusty winds, and sudden thunder squalls can cause damage to power lines, trees, temporary infrastructure, and increase safety risks outdoors. The yellow alerts are specifically calling attention to such risks.
4. Agriculture & Soil Conditions
   Late-season rainfall can influence crop harvests, soil moisture, and water management. On one hand, the rains help soil moisture; on the other, excessive rain can damage mature crops.
5. Travel, Infrastructure, and Public Safety
   Roads may become slippery or flooded, bridges or culverts may face high flows, and general mobility might be hampered during heavy showers.

Tips & Precautions for Residents

• Stay updated with local IMD bulletins and weather apps (e.g. the “Damini” app for lightning alerts, Meghdoot app for agromet advisories)
• Avoid outdoor activities during thunderstorms, especially in open fields, near trees, or in hilly terrain.
• Secure loose roofing sheets, signboards, and other lightweight structures that can be blown by gusty winds.
• Clean drainage channels ahead of time – ensure water can flow off roads and fields.
• Farmers should be cautious of overexposure of ripened crops to heavy rain-protect produce if possible.
• In areas prone to waterlogging or poor drainage, keep children and vulnerable individuals away from flooded patches.

Outlook

While the precise strength and path of the anticipated low-pressure system are still uncertain, the consensus across multiple forecasts is clear: Odisha is likely to see an active weather spell through mid-October. Thunderstorms, intermittent heavy rains, and gusty winds are expected to persist, especially with the possibility of a new system forming over the Bay of Bengal. This scenario could postpone the monsoon’s exit and keep rainfall intermittent even in the post-monsoon window.

With this in mind, communities, local authorities, farmers, and residents should remain vigilant, plan for sudden weather shifts, and make safety a priority in the days ahead.
