Cyclone Murasu makes landfall near Ongole, intensifies northeast monsoon in TN
Synopsis
Key Takeaways
Severe Cyclonic Storm Murasu crossed the southern Andhra Pradesh coast near Ongole in the early hours of Tuesday, 3 November, bringing heavy rainfall, powerful winds, and rough sea conditions to coastal regions of Andhra Pradesh, northern Tamil Nadu, and Puducherry. The landfall, confirmed by the India Meteorological Department (IMD), occurred between 3.30 am and 5.30 am IST, intensifying an already active northeast monsoon season across the region.
Landfall Details and Wind Intensity
According to the IMD, the cyclone made landfall between Nellore and Narsapur, near Ongole, at approximately latitude 15.53°N and longitude 80.22°E. Sustained wind speeds at landfall were recorded at 100–110 kmph, with gusts reaching 120 kmph. The system had developed over the southwest and adjoining west-central Bay of Bengal before intensifying into a severe cyclonic storm early on Monday, subsequently tracking northwestwards and then west-northwest towards the Andhra Pradesh coastline.
Impact on Andhra Pradesh and Puducherry
Southern Andhra Pradesh bore the brunt of the storm's approach on Monday night, with Ongole and its surrounding coastal areas experiencing powerful winds and intense rainfall. In Chirala, strong winds uprooted trees, while high waves battered several stretches of the coastline. Sea conditions grew increasingly rough as the cyclone's central circulation neared Ongole, raising concerns over flooding, infrastructure damage, and disruption to daily life in coastal settlements.
Puducherry recorded continuous rainfall from midnight, with the union territory's weather conditions significantly affected by the cyclonic system's outer bands.
Effect on Tamil Nadu's Northeast Monsoon
Although the cyclone's centre moved towards Andhra Pradesh, its influence extended southward, unsettling weather across northern Tamil Nadu. The storm's approach amplified the northeast monsoon's intensity over the state, which was already entering an active phase driven by successive Bay of Bengal systems. Prior to landfall, Murasu had been positioned approximately 160 km from Chennai and 180 km from Nellore.
Broader Monsoon Context
This comes amid a historically active northeast monsoon cycle, with cyclonic systems over the Bay of Bengal repeatedly influencing rainfall patterns across Tamil Nadu and neighbouring coastal states. The northeast monsoon, which typically accounts for the bulk of Tamil Nadu's annual precipitation, has been gaining strength through late October and early November. Notably, coastal communities remain on alert as post-landfall remnants of such systems can continue to deliver heavy rain well inland.
Authorities in both Andhra Pradesh and Tamil Nadu are monitoring the situation closely as the weakening system moves further inland, with residual rainfall expected to continue over the next 24–48 hours.
