Cyclone Yaas may have a shorter lifespan than Amphan, but that doesn’t mean it will be any less destructive
Cyclone Yaasis likely to turn into a ‘very severe cyclonic storm’ once it hits the Indian coast on May 26.
- This is the fourth time that a cyclone is hitting India within the month of May, and the second cyclone that the country has had to brace for in as many weeks.
- Climate change is pegged to be behind the rapid face of intensification of the cyclone and its increasing potential to cause damage.
- According to Indian Meteorological Department (IMD), Yaas is likely to hit the Indian coast between Paradeep in Odisha and the southern coast of West Bengal.
“It is very likely to move slowly north-northwestwards, intensify further into a ‘severe cyclonic storm’ during the next 24 hours and into a ‘very severe cyclonic storm’ during subsequent 24 hours.”
This is the fourth time that the month of May will be witnessing two or more cyclones. There were two cyclones in May in 2018 and 2004, and three in 2010.
When Amphan — a category 5 cyclone — hit the western Indian coast last year, India was in the clutches of the first wave of COVID-19. And the storm caused $13 billion in damage.
It was the costliest cyclone ever to brew in the north Indian Ocean breaking the previously held record by Cyclone Nargis, which hit in 2008.
So far, predictions by weather models peg that Yaas will at least be a category 3 storm, with the potential to escalate to a category 4. Even though it’s likely to have a shorter lifespan than Amphan, according to meteorologist Akshay Deoras, its destructive power is likely to be just as intense.

Climate change is making cyclones stronger in a shorter time span
The rapid intensification of Cyclone Amphan from a cyclone to a super cyclone in about 40 hours, last year, was pegged to be a sign of a warming Bay of Bengal — a consequence of global warming, according to experts.
The same was seen with Cyclone Tautkae, last week. Its pace of intensification and the duration of its rage were unexpected. And, again, experts pointed to climate change.
With Cyclone Yaas, history seems all set to repeat itself. The Bay of Bengal is very warm. As the storm moves in, its sea surface temperature (SST) of between 30 to 31 degrees Celsius will be one of the main factors that could quickly intensify the storm.
The IMD predicts that wind speeds with Yaas will reach a maximum of 155-165 kilometres per hour on May 26, with gusts speeding up to 180 kilometres per hour.
According to Deoras, tropical cyclones generally form further to the south over the Bay of Bengal. If the model predictions about Cyclone Yaas hold true, it will become the most intense tropical cyclone that formed so close to the Odisha and West Bengal coasts in the month of May since 1980.
The damage of Cyclone Yaas is likely to extend beyond Odisha and West Bengal
Cyclone Yaas is expected to make landfall on the Indian coast between Paradeep in Odisha and the southern coast of West Bengal.
The precise location of most rainfall will depend on Cyclone Yaas’ landfall trajectory. Odisha and West Bengal may bear the worst of the impact, but the ensuing heavy rainfall puts other areas like Jharkhand, Sikkim, Bihar, Assam and Meghalaya at risk of flooding.
In India’s neighbouring nation of Bangladesh, more than 75,000 volunteers have been put on standby to deal with the possible effects of Cyclone Yaas.
