Cyclone Murasu drums up fresh worry for Andhra after Arnab; red alert sounded in five districts

Cyclone Murasu is a tropical storm that formed over the southeast Bay of Bengal and moved west-northwest toward Andhra Pradesh. The IMD expected it to strengthen into a severe cyclonic storm before landfall. Its path matters because coastal districts may face destructive winds, heavy rain, flooding, and disruption soon after Cyclone Arnab struck the state.

The IMD placed Murasu over the southwest and west-central Bay of Bengal on November 1. It was about 630 kilometres east-southeast of Nellore and 640 kilometres southeast of Machilipatnam. Initial estimates put landfall near Bapatla between 11.30 p.m. on November 2 and 4 a.m. on November 3.

The broader forecast placed landfall between Nellore and Narsapur during the night of November 2-3. The storm was expected to bring winds of 100 to 110 kmph, gusting to 120 kmph. Officials and residents needed to follow fresh IMD warnings because the track and landfall location could still shift.

Murasu was expected to intensify from a cyclonic storm into a severe cyclonic storm by the morning of November 2. That classification signals a serious coastal threat. The main hazard specified in the forecast is powerful wind, which can damage buildings, trees, electric poles, roads, crops, and transport systems.

The IMD forecast sustained winds of 100 to 110 kmph near landfall, with gusts reaching 120 kmph. The storm was expected to cross the south Andhra Pradesh coast between Nellore and Narsapur during the night of November 2-3. The article also mentions isolated heavy rainfall in a few north coastal districts.

However, the article does not provide a rainfall amount, such as millimetres or a district total. Therefore, the wind forecast is precise, while the rainfall information is qualitative. Residents should rely on updated IMD warnings because the storm’s track, rainfall distribution, and local effects can change as it approaches the coast.

A red weather alert is the highest level of public warning used for dangerous conditions. It tells people that severe weather is likely and may threaten life, property, crops, electricity, roads, and transport. The warning matters because Murasu was approaching soon after Arnab had already caused major disruption in Andhra Pradesh.

The article lists five districts under a red alert for November 2: Krishna, Guntur, Bapatla, Prakasam, and SPSR Nellore. These districts lie along or near the central and southern coastal areas expected to bear much of Murasu’s impact. Forecast winds could reach 100 to 110 kmph, with gusts up to 120 kmph.

People in alerted areas should monitor IMD and government messages, secure loose items, avoid unnecessary travel, and move when authorities order evacuation. The article does not provide a detailed public-alert protocol, but its red-alert designation signals that residents and emergency services must treat the forecast as an immediate safety concern.

Murasu is especially concerning because it follows Cyclone Arnab by barely a week. Arnab crossed near Narsapur in West Godavari district on October 28 as a very severe cyclonic storm. Its damage had not been cleared when another storm began approaching, increasing pressure on residents, emergency workers, farmers, and infrastructure agencies.

Arnab killed five people and submerged crops on more than 3.5 lakh hectares. It damaged about 2,425 kilometres of roads and brought down around 15,000 electric poles. The state government estimated losses at ₹4,600 crore. Arnab also forced evacuations and disrupted transportation services as authorities prepared for its impact.

Murasu was expected to affect central and south coastal Andhra Pradesh, while Arnab hit northern areas hardest. This overlap raises the possibility of further flooding, crop losses, power failures, damaged roads, and interrupted transport. It also means communities may have fewer functioning resources and less recovery time before the next emergency arrives.

Cyclone Arnab left Andhra Pradesh with severe human, agricultural, and infrastructure losses. Five people died, while crops across more than 3.5 lakh hectares were submerged. The storm damaged approximately 2,425 kilometres of roads and brought down about 15,000 electric poles. The state government put the total loss at ₹4,600 crore.

Murasu could add damage before repairs are complete. Its forecast winds of 100 to 110 kmph, with gusts up to 120 kmph, could topple more poles, trees, and weakened structures. Rainfall could create fresh flooding and waterlogging, harming standing crops and making roads difficult or impossible to use. The article specifically expects isolated heavy rain in some north coastal districts.

People could face longer electricity outages, transport cancellations, blocked roads, and further displacement. Farmers may lose both recently submerged crops and new crops affected by Murasu. The article does not quantify Murasu’s eventual damage, so these are potential consequences rather than confirmed outcomes.

The IMD tracks a cyclone by repeatedly observing its centre, direction, distance from the coast, wind strength, and likely future path. It then updates forecasts as new measurements arrive. This matters because a small change in direction or speed can shift the landfall area and alter which districts face the greatest danger.

For Murasu, the IMD reported an observation at 11.30 a.m. on November 1. The storm was moving west-northwest and lay over the southwest and west-central Bay of Bengal. Forecasters estimated its landfall window and warned that the location could change. Authorities issued a red alert for five districts and prepared for the expected impact.

State agencies use these warnings to guide public messages, emergency deployments, evacuations, and transport decisions. The article notes that Arnab prompted evacuations, halted transportation services, and alerted disaster-response forces. It does not describe the agencies’ full technical procedures, so the general process reflects established weather-response practice rather than details stated here.

Cyclones need a warm ocean surface because evaporation adds moisture and heat to the air above the water. That warm, moist air rises, lowering pressure near the surface. Air then flows inward toward the low-pressure centre and begins rotating because of Earth’s rotation. Rising air releases heat as moisture condenses, which can lower pressure further and intensify the circulation.

Over the Bay of Bengal, these ingredients can combine with disturbed weather during the northeast monsoon season. Seasonal winds and changing atmospheric conditions may help a low-pressure system organize, while warm water supplies energy. If the system remains over warm water and wind conditions allow its structure to stay together, it can strengthen from a depression into a cyclonic storm and then a severe cyclonic storm.

The article states that Murasu began as a deep depression over the southeast Bay of Bengal before becoming a cyclonic storm. It does not explain the physical formation process or provide ocean temperatures. The mechanism described here is established meteorological knowledge, applied to the storm’s reported development.
