STH stormwatch: Slideshow of Very Severe Cyclone 'Hudhud' in the Bay of Bengal (07Oct2014 till date)


Almost exactly to the day, a year after Very Severe Cyclone Phaillin
(07Oct-15Oct2013) battered the eastern coast of India, and as if resurrecting its ghost Very Severe Cyclone ‘Hudhud’ will be making landfall around Vishakapatnam tomorrow, exactly on the same date that Phaillin did so one year ago.
STH as a part of its stormwatch series maintains, a close watch on the weather activity in the Bay of Bengal and has tracked and plotted all major weather events in the Bay and elsewhere (Uttarakhand cloudburst) over the past few years.
All are recorded on this blog.
STH first reported the formation of a low pressure in the Bay of Bengal on 07Oct2014 and has thereafter maintained a close watch on the development of the cyclone which, today is the full blown 'Very Severe Cyclone Hudhud' which is breathing fire, off the coast of Andhra Pradesh.
This slide show (which is being updated on a daily basis), shows the formation and movement of the weather system from 07Oct2014 and offers other related information.
