The well marked low pressure area has further intensified into depression over Southeast Bay of Bengal and adjoining Equatorial Bay of Bengal. The system is presently centered over latitude 2.7°N and longitude 89.7°E, about 1100 km of Colombo, Sri Lanka and 1490 km of Chennai.
The system is most likely to continue to track west-northwest and gain latitude. According to weathermen, there is long sea travel left for the depression ahead along with warm sea surface temperatures in the range of 30°C to 31°C and low vertical wind shear. All these conditions are sign of further strengthening of the system.
In fact, convective cloud bands are wrapping around compact circulation. This indicates that system would induce a deep depression shortly.
According to Skymet Weather, we can expect depression to form into a tropical storm Fani either by evening of April 27 or the morning of April 28. As reiterated, by this time, the likely cyclonic storm would have reached Southwest Bay of Bengal. It would then start moving in northwest direction.
Although there is consensus among the weather models over the formation of Fani, but they are varying on timing, intensity and track. Possibilities are there that the system is most likely to re-curve towards Bangladesh and avoid hitting Tamil Nadu, but even in that case it would skirt the East Coast of India. Beginning right from Tamil Nadu to West Bengal, Fani would bring light to moderate rains and thundershowers.
Chennai would also stands a chance to see some intense showers during this time.
