Cyclone Amphan has rapidly intensified into a Very Severe Cyclonic Storm (VSCS). The storm is now centered around 11.6N and 86E, about 950 km south of Paradip and1250 km SSW of Kolkata. It will be moving nearly north for some time and then recurve to move northeast. Likely to intensify further to Extremely Severe Cyclonic Storm (ESCS) in the next 24hr. The cyclone is likely to make landfall on 20th May, in the bordering area of West Bengal and Bangladesh.

Updated on May 17, 2020 12:30 PM IST: Cyclone Amphan intensified to severe cyclonic storm

Cyclone Amphan has intensified to a severe cyclonic storm over the west central Bay of Bengal. It has moved slowly northwest in the past 12 hours and is centered about 1250 km SSW (southsouthwest) of Kolkata and 950km south of Paradip. The storm will start moving northward initially and then NNE (northnortheast). Likely to become Very Severe Cyclonic Storm (VSCS) by today evening and Extremely Severe Cyclonic Storm(ESCS) in the subsequent 24 hours. It is likely to make landfall on the 20th May morning, close to West Bengal - Bangladesh border. Adverse weather conditions with high velocity winds more than 120 kmph and extremely heavy rains are likely along and off Odisha-West Bengal coast between 18th and 20th May. Red Alert is sounded for the two states to observe utmost safety and precautions.

Updated on May 16, 2020 6:00 PM IST: Depression in Bay of Bengal intensified to Deep Depression

The deep depression in the Bay of Bengal has intensified into a cyclonic storm. The maiden cyclone, cyclone Amphan, of this season is centered around 10.5N and 86.4E, about 650km ESE (East South East) of Chennai. The system remains in favorable environmental conditions and will shortly intensify further to a severe cyclonic storm.

Landfall is expected on May 19th late night or 20th morning, Southeast of Kolkata, subject to revision. The storm will have catastrophic damaging potential with extremely heavy rains and high-velocity winds, along with and off the coast of Odisha and West Bengal.

Updated on May 16, 2020 11:30 AM IST: Depression in Bay of Bengal intensified to Deep Depression

The depression in the Bay of Bengal has intensified to a deep depression, centered around 10.5N and 86.8E. The system continues to be in favorable environment and is likely to burgeon to a significant cyclone in the next few hours, earlier than expected. The deep depression is presently located about 850km SSE of Visakhapatnam and 1100 km south of Paradip, Odisha. The system will move northwest and reach abeam Chennai, keeping a safe distance of about 600km by this evening, as a developed cyclonic storm. Thereafter, it is likely to move northward and intensify to a severe cyclonic storm in the subsequent 24 hours.

Updated on May 15, 2020 1:25 PM IST:

The well marked low pressure area southeast Bay of Bengal has intensified into a depression. The system is centered around 10.6N and 87.3E, about 900km southeast of Visakhapatnam. The depression is moving northwest and remains in a favorable environment for further development. It is likely to become a cyclonic storm by tomorrow and reach abeam Chennai at a safe distance of approximately 600km. The storm thereafter will be moving initially north and then northnortheast (NNE) and strengthen further to a severe cyclonic storm. Extreme northern parts of coastal Odisha and West Bengal will run the risk of direct impact around 19th May.

The first cyclone of this season in the Indian Seas is few knocks away. Existing low pressure area in the southeast Bay of Bengal is well marked and is poised to become 'depression' within next 24 hours. The system is in favorable environment for intensification to a cyclonic storm latest by 16th May. Though the cyclone will take a recurvature northward while over the westcentral Bay of Bengal, abeam Chennai, but the orientation of our coastline will engage the storm to make a landfall, tentatively around 18-19th May. More confident forecast can be expected after another 24 hours.

The stormy season for the Indian seas starts in March and lasts till the establishment of monsoon in June. The month of May remains the favorite and stands highest chances, double as compared to April and June. The frequency of storms is a bit higher in the Bay of Bengal than the Arabian Sea.

The first cyclone of the season has been lurching far in the southeast Bay of Bengal for fairly long. A low pressure area appeared over that region in the far end of April and kept languishing for few days and finally weakened to a cyclonic circulation. This feature has been lingering for many days with prospects swinging for and against intensification. Quite understandably, the first major system in the Indian seas after a gap of nearly 05 months will find unsettled conditions and therefore ruffle feathers before being decisive to choose its course. The preponderance of sea surface temperature (SST) for cyclogenesis is proven yet again and has been keeping the region on tenterhooks for about two weeks.

The cyclonic circulation over the Andaman Sea and Southeast Bay of Bengal is well marked. A low pressure area is likely to form in the next 24 hours. The proclivity of environmental conditions looks firm enough for cyclogenesis and the first cyclone of the season is nearly certain to come up, tentatively by this weekend.  The low pressure area will move towards the northwest and is likely to become depression/ deep depression in the subsequent 48 hours. Rapid intensification is expected thereafter to a cyclonic storm while positioned over west-central Bay of Bengal. From here on the storm will perform the dual act of intensification to a severe cyclonic storm and later to a very severe cyclonic storm. Also, the cyclone Amphan will start inching towards the coastline with a possible curvature towards the north.

Numerical Weather Models diversity about the timelines, area, intensification, and track remains a bone of contention. But there is a broader consensus about the formation of a significant storm in the Bay of Bengal in the next 3-4 days time.  Unlike the earlier projection of storm threatening Myanmar and Bangladesh, the entire Indian coastline from Andhra Pradesh to Odisha and extending to West Bengal falls under the striking range of this cyclone. A precise forecast with more clarity is possible after 48hrs on becoming a depression or deep depression.

The environmental conditions have gathered in a good number to support this system. The sea surface temperature (SST) has played the lead role to be above the threshold mark with a sufficient margin. The entire Bay of Bengal is warm enough to sustain the growth of the system.


MJO after winning the initial bout during the fag end of April has appeared again over the Indian Ocean. Its presence over phase 2&3 over the ocean will enhance flaring the convection over the area and this oceanic parameter lasts all through the life cycle of the storm as substantial support.


This storm will be instrumental in ushering on-time arrival of monsoon over the Andaman Sea anytime around 16-17 May. The proximity of the storm to our coastline will necessitate adequate precautions with timely preparations. Suffice to say: be watchful and stay safe.
