India Met Department (IMD) has declared the formation of tropical
cyclone ‘Vardah’ in the Bay of Bengal as yesterday Dec 07,2016's depression
intensified twice over in strength during the night.
‘Vardah’ has been located 210 km west-south-west of Port Blair in the
Andaman & Nicobar Islands early this morning. It is expected to
reach peak strength of a severe cyclone.
It is long way still to India’s East Coast, its final destination,
giving it ample time and space to pump up even more strength, and even
lose some.
‘Vardah’ may weaken slightly just before landfall due to unfavourable
environment closer to the coast (as in cooler waters and increasing
‘shear’ of wind at the higher levels of the atmosphere).
IMD has officially put the Andhra Pradesh coast as the likely area of
the landfall. But it has not set any date or mentioned an exact location
for this to happen.
Transformation of the depression into cyclone took place at a ‘blinding
speed’ since and less than 100 km that the depression had covered from
yesterday to early this morning
It had remained practically silent during the course of the day
yesterday and had revved back to activity towards midnight last night.
Within the space of a few hours into the small hours into this morning Dec 08,2016,
it was able to spin up the power required to claim cyclone status.
IMD located ‘Vardah’ over South-East Bay of Bengal to 1,090 km to the
south-east of Visakhapatnam (Andhra Pradesh); 1,170 km east-south-east
of Machilipatnam (Andhra Pradesh); 310 km to the north-west of Car
Bicobar (Nicobar Island); and 210 km to west-south-west of Port Blair
(Andaman Island).
The travel to the Andhra Pradesh coast may take the next three to four
days, giving enough time to authorities to make adequate preparations
for the face-off.
Most global models had predicted that the cyclone may make a landfall
over the Andhra Pradesh coast. The European Centre for Medium-Range
Weather Forecasts alone had suggested a different location – Chennai and
neighbourhood.
