ORIGIN OF HUDHUD
TRACK DETAILS
LANDFALL POINT AND INTENSITY
IMPACTS
CONCLUSION
Hudhud originated from a low pressure system
that formed under the influence of an upper-air
cyclonic circulation in the Andaman Sea on
October 6.
ORIGIN
A low pressure area formed over the Andaman Sea on October 6
It slowly consolidated and was upgraded to a depression by the
Indian Meteorological Department (IMD) on October 7. While
over open waters, the depression continued to encounter a
favorable environment, and a tropical cyclone formation alert
(TCFA) was issued by the Joint Typhoon Warning Center
(JTWC), followed by IMD upgrading the storm into a deep
depression.
In the early hours of October 8, the JTWC started issuing its
advisories for the system as it recorded tropical storm winds at
the storm's centre.
TRACK ING DETAILS
The IMD later reported that the deep depression made its first
landfall over Long Island, Andaman, and had reached cyclonic
storm intensity, naming it Hudhud.
After entering the Bay of Bengal, Hudhud continued to intensify
the following day, and was upgraded to a severe cyclonic storm.
Early on October 10, the JTWC classified the storm as a
Category-1 tropical cyclone after it formed a microwave eye
feature
IMD upgraded Hudhud to a very severe cyclonic storm later the
same day, and the JTWC further upgraded the storm to the “a”
Category 2 tropical cyclone.
On October 11, Hudhud underwent rapid intensification
and developed an eye at its center. In the following hours,
the storm reached its peak intensity with a minimum
central pressure of 950 mbar (28.05 in Hg) and three
minute average wind speeds of 185 km/h (115 mph) and
reached the category-3 cyclone level.
THE 12 OCTOBER, 2014
•Hudhud made landfall over Visakhapatnam, Andhra Pradesh at
noon of October 12, The maximum wind gust recorded by the High
Wind Speed Recorder (HWSR) instrument of the Cyclone Warning
Center in Visakhapatnam was 260km/h (160 mph).
• Measured by the Doppler weather radar stationed in the city, the
storm's eye was 66 km (41 mi) in diameter.
•The strength of the winds disrupted telecommunication lines and
damaged the Doppler radar, inhibiting further observations.
•Bringing extensive damage to the coastal districts of Andhra
Pradesh, Hudhud gradually weakened as it curved northwards over
land. The storm continued its weakening trend and was last noted
as a well marked low pressure area over east Uttar Pradesh on
October 14.
Landfall point and intensity
IMPACTS
•Effect on flora
•Effect on fauna
•Loss of life
•Loss of property
•Floods
•Coastal erosion
The maddening velocity of Hudhud broken and
flattened the 75-80% of city’s trees.
The most saddening sights were visible in places such
as Kailasagiri, Waltair, Steel plant and the Andhra
University campus that were earlier the most prominent
lung spaces of Vizag.
The Kambalakonda Reserve Forest too had half its trees
missing.
almost all of the 50 lakh trees covering over 40% of the
3,600 hectares of Vizag Steel Plant were found damaged
Effect on Flora
Vizag’s only Biodiversity Park which used to house
more than 1,500 species of flora has been left utterly
destroyed by the cyclone Hudhud. The park’s treasury
included a wide variety of flora including medicinal,
aromatic and ornamental plants along with palm and
bamboo groves.
At least 50,000-80,000 trees spread across 625 acres
of Zoo park were destroyed.
IMPACT ON FAUNA
• Biodiversity Park:- which used to house about 25
butterfly species found dead.
• Kambalakonda Wildlife Sanctuary:-a home to
more than 100 bird species, including a few migrant
ones. Prof D.E. Babu, head of the zoology department
at Andhra University, said, “Birds have no place left
to dwell and breed in the city as their habitat has been
left completely devastated.
• Some of the birds found commonly include White
Bellied Sea Eagles, Barn Owl, Pariah Kites, Common
Kestrel, Osprey, Drongo, Egret, Hornet Owl among
others. Prof De Babu says, "The effect of this loss in
tree cover is not limited to just birds but also
microbats (small sized bats) and other small tree
dwelling mammals and reptiles.With the heavy loss of
canopy cover in the Kamabalakonda Wildlife
Sanctuary.
• Impact on olive ridleys:-As per a survey done by
NGO Green Climate and Environmental Film Society,
Cyclone Hudhud not only swept away the green cover of
the city from Ramakrishna Beach to Bheemili, but also
made an impact on the nesting habitats (sand dunes) of
Olive Ridley turtles along the city's beaches , nearly 50%
drop in the number of turtles visiting the North Andhra
coastline last year," stated Green Climate JV Ratnam.
LOSS OF LIFE
Heavy rains along with strong winds caused
deaths
61 people died in Andhra Pradesh.
Total 81 deaths reported in India.
44 deaths in Nepal due to an Avalance induced
by Hudhud.
LOSS OF PROPERTY
The Indian Navy suffered a loss of Rs 2,000
crore due to the severe cyclonic storm Hudhud.
Vizag Steel Plant, the biggest public-sector
enterprise, suffered damages of Rs 340 crore.
The plant was also losing daily Rs 40 crore due
to the loss of production.
Vizag Airport suffered a loss of Rs 500 crore.
The airport's roof was blown away while its
communication network collapsed.
40,000 electricity poles were damaged in Vizag.
Total Damages were estimated to be 21908 crore by the
Andhra state government.
FLOODS
Hudhud caused extensive rains in Visakhapatam,
Vijayanagaram, Srikakulam districts in
Andhrapradesh and in south Orissa and
Chattisgarh.
Coastal Erosion
LESSONS TO BE LEARNT FROM HUDHUD
Mangroves and casuarinas plantations along the
coast and the thick tree cover on the hills used to
protect the city in the past from the vagaries of
cyclones.
Cyclone shelters need to be maintained in a state of
readiness.
Gram sabhas in villages can play a crucial role in
facing calamities. If fallen trees could be cleared along
many lanes in the city within five days after the
cyclone, the credit should go to self-help groups and
some NGOs. The government should, therefore, involve
civil society as a part of any disaster management
effort in the future.
CONCLUSION
Hudhud-This was nothing but the name of a bird
before the 12th of October 2014 but after the 12th ,this
term became a symbol of destruction, brother of
Phailin!
IMD failed to forecast the intensity of Hudhud, said
that the wind speed could be around 160kmph during
landfall on their 10th early morning bulletin, only
JTWC succeed in predicting the intensity. So
predictions should be more accurate, in order to reduce
loss of life and property by taking precautionary steps.
