Bhubaneswar: Even as Cyclone Yaashas made landfall at 15km south of Balasore with a packing wind speed of 120kmph, the fact to the fore is its wind speed has been the lowest since 1999.
Though Cyclone Daye that hit Odisha in 2018 had a lower wind speed, but it wasn’t in the category of Very Severe Cyclonic storm (VSCS).
Sample the following
After witnessing two back to back cyclones in year 1999 – Very Severe Cyclonic storm and Super Cyclone, Odisha had braced up with a cyclone again in year 2013, when Extremely Severe Cyclonic storm Phailin hit Gopalpur (Ganjam).
Significantly, since 2018, Odisha has been regularly getting hit by cyclones.
In 2018, Odisha was hit by 2 cyclones successively – Cyclone Daye in September and Very Severe Cyclonic Storm Titli in October.
However, since then cyclones have become an annual feature in Odisha.
Since 2019, summer cyclones have become a regular feature in Bay of Bengal. And the hit rate has been nearly 67 per cent.
During the period of 2019-21, the Bay had brewed 3 cyclones – an extremely severe cyclone Fani, Super Cyclone Amphan and very severe cyclonic storm Yaas, and Odisha takes a hit by two – Fani and Yaas.
Titli Vs Yaas
While Titli had been a post monsoon cyclone as against Yaas being a pre-monsoon cyclone, Titli had been highly  destructive than Yaas, though both are very severe cyclonic storm with a central pressure of 972 and 974 mb, respectively.
The sustained wind speed of Titli was over 150 kmph gusting upto 185-190kmph.
Cyclone Yaas’ sustained speed has been 120 kmphgusting upto 165kmph.
RAINFALL: TITLI Vs YAAS
As per IMD data, pounding by Titli is heavier than Yaas. Sample the following.

*In contrast, the highest rainfall recorded had been 228mm.
Moreover, while Titliwrecked havoc in Odisha, especially Gajapati district taking heavy toll on human lives and property.
A comparative analysis of all cyclones since 1999 that had made landfall in Odisha shows that Cyclone Yaas has been the least furious, despite in the category of VSCS.
CYCLONE YAAS AND MONSOON
As per model indications, monsoon in Odisha is not going to see it’s onset on June 10 – the normal onset date in State.
Though due to prevailing easterly winds, monsoon is all set to cover the entire north east and West Bengal by June 10. But State has to wait for few more days
