.
▪️Overall confidence in the forecast is high as an Upper Air Circulation has formed over South-East BoB adjoining South Andaman Sea.
And MJO signal found over Phase 3 with amplitude less than 1 and likely  to gain amplitude over Eastern Equatorial Indian Ocean(ph 2-3) , which is favourable for Tropical Development over Bay of Bengal.
Also Sea Surface Temperature is very high(30-32°C) over major parts of the sea, which is very conductive for the development process.
.
Wind Shear is likely to be Low to Moderate (⬇) over the development area during 5-8 May. Also other relevant parameters are likely to be favourable during the forecast period.
The combination of these parameters could cause very favourable environment through the whole forecast period.
