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.
