Cyclone Arnab: IMD Issues Rain Alerts for Jharkhand

Jharkhand has been placed on weather alert as Very Severe Cyclonic Storm Arnab threatens to bring three days of heavy rainfall, thunderstorms, lightning and gusty winds. The India Meteorological Department (IMD) has issued yellow and orange alerts for several districts, while authorities have warned of urban flooding, waterlogging and possible damage to standing crops.

The approaching cyclone is projected to make landfall along the Andhra Pradesh coast on Wednesday, with its wider weather impact expected to extend into Jharkhand. State authorities have urged district officials to remain vigilant, particularly in low-lying areas vulnerable to flooding and in locations where strong winds could damage temporary structures.

The IMD has forecast widespread thunderstorms, lightning and gusty winds through Friday. Rainfall intensity is expected to increase after the initial alert period, prompting an orange alert for seven districts until the morning of October 30.

IMD Issues Yellow Alert for Eight Jharkhand Districts

The IMD has issued a yellow alert warning of heavy rainfall across eight districts of Jharkhand for 24 hours beginning at 8:30 am on October 28.

The districts covered by the yellow alert are:

• Ranchi
• Khunti
• Simdega
• Gumla
• Lohardaga
• Saraikela-Kharsawan
• East Singhbhum
• West Singhbhum

The warning indicates that residents and local authorities should remain alert to changing weather conditions. Heavy rainfall can cause water to accumulate on roads, disrupt local transport and increase the risk of flooding in vulnerable areas.

Residents in low-lying neighbourhoods, particularly those that experience recurring waterlogging, should monitor official Weather Updates and follow instructions issued by district administrations.

Orange Alert for Seven Districts Until October 30

As rainfall intensity is expected to increase, the IMD has issued an orange alert for seven districts of Jharkhand. The warning remains in effect until the morning of October 30.

The districts under the orange alert are:

• Garhwa
• Palamu
• Latehar
• Lohardaga
• Gumla
• Simdega
• West Singhbhum

The orange alert signals the need for heightened preparedness because adverse weather could create disruptions and localised hazards. Residents should pay attention to official forecasts and advisories, especially if rainfall becomes persistent or conditions deteriorate rapidly.

Several districts appear in both the yellow and orange alert lists, including Lohardaga, Gumla, Simdega and West Singhbhum. This reflects the different alert periods and the forecast escalation in rainfall intensity described by the IMD.

Cyclone Arnab’s Movement Over the Bay of Bengal

In a post on X, the IMD said the very severe cyclonic storm over the west-central Bay of Bengal had moved west-northwestwards at approximately 20 kmph during the preceding six hours.

At 8:30 am, the storm was centred over the same region, approximately 220 kilometres south-southeast of Visakhapatnam in Andhra Pradesh, according to the department’s update.

The storm’s projected landfall on the Andhra Pradesh coast is expected to influence weather conditions beyond the immediate coastal region. For Jharkhand, the primary concerns highlighted in the forecast are heavy rainfall, thunderstorms, lightning and gusty winds.

Such conditions can create risks even in areas away from a cyclone’s landfall location. Heavy rain may overwhelm drainage systems, while lightning and strong wind gusts can endanger people outdoors and damage weak structures.

The IMD has warned that thunderstorms, lightning and gusty winds could continue through Friday. Residents should therefore avoid assuming that conditions will improve immediately after a period of lighter rain.

Ranchi Administration Orders Vigil in Flood-Prone Areas

With heavy rainfall forecast, Ranchi Deputy Commissioner Manjunath Bhajantri has instructed officials to maintain continuous vigilance in areas vulnerable to urban flooding, waterlogging and agricultural runoff.

The direction places particular emphasis on low-lying locations where rainwater can accumulate quickly. Urban flooding can develop when intense rainfall exceeds the capacity of drains and other water-management infrastructure, leaving roads and residential areas temporarily inundated.

The Ranchi district administration has also warned of possible damage to standing crops and risks to temporary shelters and structurally weak buildings.

In its advisory, the administration said waterlogging was likely on city roads and in low-lying sectors. It cautioned that standing crops could sustain damage, while temporary shanties and weak structures could be affected by gusty winds.

Officials have urged residents in flood-prone zones to take precautions and remain attentive to instructions from local authorities. Continued monitoring is particularly important if rainfall persists or water levels rise in vulnerable areas.

Heavy Rain Could Affect Roads, Crops and Temporary Structures

The expected weather conditions pose several risks across Jharkhand, although the severity of the impact will depend on local rainfall intensity, drainage conditions and wind speeds.

Urban Waterlogging and Local Flooding

Heavy rainfall can lead to water accumulating on city roads, in low-lying neighbourhoods and around areas with inadequate drainage. Waterlogged roads may disrupt traffic, slow emergency movement and make routine travel difficult.

Residents should avoid walking or driving through flooded stretches when the depth or current of the water is uncertain. Water covering a road can conceal potholes, open drains and other hazards.

Risks to Standing Crops

Prolonged or intense rainfall can damage standing crops, particularly where fields remain waterlogged or drainage is poor. Agricultural runoff may also affect fields and nearby roads.

Farmers in affected districts should monitor local weather advisories and seek guidance from relevant agricultural authorities on precautions appropriate to their crops and field conditions.

Strong Winds and Vulnerable Buildings

Gusty winds can damage temporary shelters, unsecured outdoor materials and structurally weak buildings. Residents should secure loose items where it is safe to do so and avoid standing near unstable structures, trees or objects that could fall during strong winds.

People living in temporary shanties or other vulnerable structures should pay close attention to local administration instructions and move to safer locations if authorities advise evacuation.

Safety Precautions for Residents During the Weather Alert

Residents across the affected districts can reduce their exposure to weather-related hazards by following a few practical precautions during the alert period.

• Monitor official updates: Follow the latest IMD forecasts and district administration advisories as the cyclone and associated weather systems develop.
• Avoid flooded roads: Do not attempt to cross waterlogged roads or flowing water when conditions are uncertain.
• Take lightning seriously: Seek shelter indoors during thunderstorms and avoid exposed outdoor locations.
• Secure loose objects: Where safe, secure items that could be displaced by gusty winds.
• Stay away from weak structures: Avoid taking shelter beside unstable walls, damaged buildings or other structures that may be vulnerable to strong winds.
• Protect essential supplies: Keep phones charged and essential medicines and important documents accessible in case local conditions disrupt travel or services.
• Follow official instructions: Residents in vulnerable areas should comply with any evacuation or safety directions issued by local authorities.

These precautions are particularly relevant for people living in low-lying areas, residents of temporary structures and those who must travel during periods of heavy rain or thunderstorms.

What Residents Should Expect Over the Next Three Days

The IMD’s forecast points to a period of unsettled weather across parts of Jharkhand, beginning with a yellow alert from the morning of October 28 and escalating to an orange alert in seven districts until the morning of October 30.

Thunderstorms, lightning and gusty winds are expected to remain concerns through Friday. The exact timing and intensity of rainfall may vary by district, so residents should continue checking local updates rather than relying on a single forecast issued earlier in the warning period.

The district administrations’ response will be important in identifying vulnerable locations, monitoring waterlogging and communicating any changes in risk. Residents can support these efforts by avoiding unnecessary exposure to hazardous weather and following instructions from officials.

Conclusion

Cyclone Arnab has prompted weather alerts across Jharkhand, with the IMD warning of heavy rainfall, thunderstorms, lightning and gusty winds over a three-day period. Eight districts are covered by the initial yellow alert, while seven districts face an orange alert until the morning of October 30.

Authorities have highlighted the risk of urban flooding, waterlogging, agricultural damage and problems for temporary or structurally weak buildings. Ranchi officials have directed teams to maintain vigilance in vulnerable areas and urged residents in flood-prone locations to take precautions.

With weather conditions expected to remain unsettled through Friday, residents should monitor official forecasts, avoid flooded roads and follow local safety instructions. The situation may change as the storm progresses, making timely updates and local preparedness essential.
