Cyclone Fengal: A Updates, advisory and impacts...
Cyclone Fengal, a developing cyclonic storm over the Bay of Bengal, has captured national attention as it approaches the Tamil Nadu and Puducherry coasts. The storm, which began as a depression on November 25, 2024, intensified into a deep depression before escalating into a cyclonic storm by November 29, 2024. This natural phenomenon underscores the importance of preparedness as it threatens to bring heavy rainfall, strong winds, and potential flooding to coastal regions.
How Cyclone Fengal Formed
Cyclones typically form over warm ocean waters, where heat and moisture provide the energy needed to develop a low-pressure system. Cyclone Fengal followed this pattern, originating as a depression in the Bay of Bengal and intensifying due to favorable conditions such as high sea surface temperatures. The storm was tracked using advanced satellite systems like ISRO’s EOS-06 and INSAT-3DR, which provided crucial data on wind circulation and cloud patterns. These technological tools have allowed for early detection and improved forecasting, enabling authorities to plan mitigation strategies.
Why It’s Called Cyclone Fengal
Cyclone names are assigned from a pre-determined list contributed by countries in the World Meteorological Organization (WMO) panel. "Fengal" was selected from this list, adhering to guidelines that ensure names are easy to pronounce, unique, and culturally neutral. The name signifies the latest in a series of storms originating in the Indian Ocean region.
Current Position and Path
As of November 29, 2024, Cyclone Fengal was located approximately 260 km east of Nagapattinam, 270 km east-southeast of Puducherry, and 300 km southeast of Chennai. The IMD has forecast that the storm will move west-northwestwards, making landfall between Karaikal and Mamallapuram, close to Puducherry, on the afternoon of November 30. Upon landfall, wind speeds are expected to reach 70-80 kmph, with gusts up to 90 kmph.
Impacts on Tamil Nadu and Puducherry
The cyclone is predicted to bring widespread impacts, particularly in coastal districts. Heavy rainfall, with isolated extremely heavy showers, is expected in Chengalpattu, Villupuram, Cuddalore, Mayiladuthurai, and Nagapattinam districts, as well as in Puducherry and Karaikal. In Chennai and its surrounding districts, moderate to heavy rainfall is likely, accompanied by strong winds that could disrupt normal life. Flooding and waterlogging are significant concerns in low-lying areas, while high winds may lead to property damage, uprooted trees, and power outages. The fishing community has been particularly vulnerable, with rough seas prompting the return of over 4,100 fishing boats to the shore. The government has advised against any fishing activities until the weather improves.
Government Advisories and Safety Measures
The Tamil Nadu government and disaster management teams have taken proactive steps to minimize the cyclone’s impact. Relief centers have been set up in vulnerable districts such as Nagapattinam, Tiruvarur, and Cuddalore. In these areas, 471 people from 164 families have already been evacuated to safety. The National Disaster Response Force (NDRF) is on high alert, with teams deployed in key districts like Chennai, Mayiladuthurai, and Chengalpattu. Essential equipment such as boats, generators, and motor pumps have also been readied for rescue and relief operations.
In response to the impending storm, schools in Chennai, Chengalpattu, and other districts were closed on November 29 to ensure the safety of students. Authorities have urged residents to stay indoors, secure loose objects, and keep emergency supplies on hand. Coastal communities have been advised to avoid venturing out during heavy rains and strong winds.
ISRO Technological Support for Monitoring
ISRO's satellites have played a pivotal role in tracking Cyclone Fengal. The EOS-06 satellite, equipped with a scatterometer sensor, detected ocean wind patterns and helped forecast the storm’s development. This technology provided valuable lead time for authorities to issue warnings and implement safety measures. By leveraging such advanced tools, disaster preparedness has become more effective, reducing the risks posed by cyclonic storms.

Alerts and Warnings
The IMD has issued a red alert for several districts, including Chengalpattu, Villupuram, Cuddalore, Mayiladuthurai, Nagapattinam, Puducherry, and Karaikal. These areas are expected to experience extremely heavy rainfall and strong winds. A yellow alert is in place for Chennai, Tiruvallur, and Kancheepuram, indicating moderate to heavy rainfall with gusty winds.

What Lies Ahead
As Cyclone Fengal approaches landfall, residents of Tamil Nadu and Puducherry must remain vigilant and follow official advisories. With disaster management teams on high alert and relief measures in place, the region is better equipped to handle the storm's impact. However, cooperation from the public is crucial to ensure safety and minimize disruptions. Cyclones like Fengal serve as reminders of the power of nature and the importance of preparedness. By staying informed and adhering to government guidelines, communities can weather the storm safely and effectively.
