A developing cyclonic system over the Bay of Bengal, named Cyclone Arnab, may influence weather conditions across Bihar, with rainfall activity expected to increase in several parts of the state from October 28. According to the weather department's forecast, an orange alert has been issued for thunderstorms, lightning and b winds on October 29. Wind speeds could reach 40–50 kilometres per hour during this period. The anticipated change in weather may bring relief from the heat, but b winds, lightning and rainfall could also disrupt normal life.
The cyclonic system developing over the Bay of Bengal is gradually intensifying. Its influence is expected to bring changes in weather conditions across several eastern Indian states. According to meteorologists, the system may increase moisture levels over Bihar and accelerate cloud movement, potentially triggering rain accompanied by thunderstorms and lightning in several districts.
However, the primary effects of the cyclone in Bihar are expected to take the form of rainfall, b winds and lightning. The actual weather conditions will depend on the system's direction and intensity.
Most parts of Bihar are expected to experience generally normal weather on October 27, but conditions could begin to change from October 28. Light to moderate rainfall may start in some districts, while weather activity could intensify on October 29. Several areas may face b winds, lightning and an increased risk of thunderstorms.
Rainfall is also possible in many parts of the state on October 30. Rain and thunderstorm activity may continue in some areas until October 31. Residents are advised to monitor weather warnings issued for their respective districts.
Weather conditions may also change in Patna and several parts of southern Bihar. Cloud cover and rainfall could lead to a decline in temperatures. However, heavy rain may cause waterlogging on city roads, disrupt traffic and damage items left in exposed areas.
If wind speeds increase, branches of weak trees could break, while temporary structures may sustain damage. Residents should avoid unnecessary outdoor movement during adverse weather conditions.
Districts in northern Bihar are also expected to remain alert to the possibility of rainfall and b winds. Weather developments in West Champaran, East Champaran, Gopalganj, Siwan and surrounding areas will require close monitoring. Some districts in southern Bihar may also experience the effects of rainfall.
Rainfall intensity is not expected to be uniform across the state. Some locations may receive light showers, while others could experience heavier rainfall accompanied by thunderstorms and b winds. District-level warnings may be revised in line with the weather department's latest forecasts.
The potential impact of the cyclonic system could also affect agricultural activities. During the final week of October, harvesting of kharif crops and the removal of produce from fields are under way in several areas. Rainfall during this period could affect standing crops, harvested grain stored in the open and ongoing agricultural operations.
Strong winds may cause crops to lodge, while persistent rainfall could lead to water accumulation in fields. Farmers need to plan harvesting and storage activities according to weather forecasts. Grain kept in the open should be moved to a safe location or covered with tarpaulins, where necessary, to reduce potential rain-related losses.
With lightning expected to pose a risk on October 29, residents should exercise particular caution. During lightning and thunderstorms, people should avoid remaining in open fields, agricultural land or areas near rivers and ponds. Standing under trees can also be dangerous. People should seek shelter inside a permanent building and maintain distance from electricity poles, power lines and metal structures.
During b winds, residents should avoid standing near weak walls, hoardings and temporary structures. Before travelling in adverse weather, they should check road conditions and the latest weather information.
With wind speeds potentially reaching 40–50 kilometres per hour, precautions will be necessary in both rural and urban areas. Lightweight objects left in open spaces could be blown away. Items placed on rooftops and balconies should be secured.
Farmers, construction workers and people working outdoors should move to safe locations when weather conditions deteriorate. Rain could make roads slippery, while low-lying areas may experience water accumulation, potentially causing difficulties for commuters.
The anticipated rainfall could also affect temperatures across Bihar. Cloud cover and rain may lower daytime temperatures, while mornings and evenings could feel relatively cooler. The extent of any temperature decline will depend on rainfall amounts and local weather conditions.
The changing weather during the final days of October could affect daily routines. Children and elderly people should avoid unnecessary outdoor exposure during adverse weather, while residents should take precautions when travelling.
In view of the potential impact of Cyclone Arnab, residents across Bihar should continue monitoring the weather department's latest bulletins. With rainfall activity expected to increase from October 28 and an alert for thunderstorms and lightning issued for October 29, advance precautions will be important.
Farmers should prepare to protect crops and stored grain, while residents are advised to seek safe shelter during b winds and lightning. Forecasts may change if the direction or intensity of the weather system changes. Daily activities and travel plans should therefore be based on the latest official weather information.
