As expected, the deep depression in west-central Bay of Bengal has intensified into a cyclonic storm Daye. It is now seen over west-central and adjoining north-central Bay of Bengal.
The cyclone is presently centered at latitude 18.1°N and longitude 86.3°E, around 100 km southeast of Gopalpur, Odisha, around 160 km east of Kalingapatnam, Andhra Pradesh and 450 south-southwest of Kolkata, West Bengal.

Updated on September 20. 2018 2 PM: Monsoon 2018: Cyclone threat in Bay, Odisha and Andhra on alert for torrential rains
Cyclone threat has been looming large over the East Coast of India. According to Skymet Weather, the deep depression in west-central Bay of Bengal is all set to intensify into a cyclonic storm shortly. If this happens, it would be named as ‘Daye’.
According to Skymet Weather, weather conditions are ripe for the formation of a cyclone in the Bay of Bengal. Sea surface temperatures are around presently around 29°C, which are extremely conducive for the strengthening of the weather system. Vertical wind shear is also low that further aides the system in getting more marked. Following image will help you understand better. 
However, with less sea travel left, we expect this system to become a tropical storm for short duration.
The system is most likely to cross the Indian coast between Kalingaptanam, Andhra Pradesh and Puri, Odisha near Gopalpur by midnight as a cyclonic storm.
At present, the system is centered at latitude 17.6°N and longitude 86.8°E, around 280 km east-southeast of Kalingapatnam, Andhra Pradesh and about 265 km east-southeast of Gopalpur, Odisha.
In wake of this, both the coastal states have already been put on alert. Torrential Monsoon rains are likely to lash coastal areas of Odisha and Andhra Pradesh during the next 24 hours.
High velocity winds to the tune of 50-60 kmph can already be seen blowing along the coast. We can expect wind speed to even increase further to the tune 80-90 kmph at the time of landfall.
As per weathermen, torrential rains, squally winds and lightning strikes can be dangerous combination and could have some devastating results. We are afraid that all the three events could be witnessed tonight along Odisha-Andhra coast. In fact, parts of Gangetic West Bengal, Jharkhand and Chhattisgarh would also come in firing range of the system, bringing heavy rains.
The peripherals of the system would also give good rains over Rayalaseema, Telangana North Interior Karnataka and North coastal Tamil Nadu as well.
Sea conditions have already become rough to very rough off and along the entire East Coast. Fishermen and locals are advised not to venture out in the sea for the next 48 hours. However, as the systems crosses the coast, we expect it to weaken into a deep depression again. But even as the weakened system, it would be capable of giving torrential rains over most parts of the country.
By September 21, along with the above mentioned areas, rain belt would also start lashing East Madhya Pradesh, Maharashtra, and Bihar. Weathermen predict that rains would keep shifting with the system. Though rains would vacate Odisha and Andhra Pradesh by September 22, but at the same time rain would tighten grip over the central parts of the country that include entire Madhya Pradesh, Uttar Pradesh, and parts of Rajasthan and Gujarat.
By September 23 and 24, northwestern plains of Delhi, Punjab and Haryana would also start receiving rains. According to Skymet Weather, barring extreme southern parts of Southern Peninsula, the system would be responsible giving rains over the entire country.
