Phailin; An IntroductionVery Severe Cyclonic Storm

(Thai: meaning "sapphire")

On October 4, 2013 the Japan Meteorological Agency started to monitor

a tropical depression that had developed in the Gulf of Thailand

The second-strongest tropical cyclone ever to make landfall in India.

It caused substantial damage to Odisha and AP.

Biggest evacuation ever in last 23 years in India.

Genesis & Pathway

6 th October - Tenasserim coast 7 th October – Andaman sea 8 th October – Andaman sea It concentrated into a depression at12.00N and longitude 96.00E

4


Genesis & PathwayMoving north-westwards, it intensified into a deep depression on 9th morning and further into cyclonic storm (CS)

In the same day evening. Moving north-westwards, it further intensified into a severe cyclonic storm (SCS) in the morning and into a VSCS in the forenoon of 10th Oct. over east central Bay of Bengal.

Salient features

VSCS PHAILIN is the most intense cyclone that crossed India coast after Odisha Super Cyclone of 29th October 1999.

There was rapid intensification of the system from 10th Oct. morning to 11th October morning leading to an increase in wind speed from 45 knots to 115 knots.

.

8


Salient features At the time of landfall on 12th Oct, maximum sustained surface wind speed

in association with the cyclone was about 115 knots (215 kmph) and estimated central pressure was 940 hPa with pressure drop of 66 hPa at the centre compared to surroundings.

It caused very heavy to extremely heavy rainfall over Odisha leading to floods, and strong gale wind leading to large scale structural damage and storm surge leading to coastal inundation over Odisha.

9


Salient features The numerical weather prediction (NWP) and dynamical statistical models

provided good guidance with respect to its genesis, track and intensity. Though there was divergence in model guidance with respect to landfall point in the initial stage, the consensus among the models emerged as the cyclone moved closer to the coast.

IMD accurately predicted the genesis, intensity, track and point & time of landfall and also the adverse weather like heavy rainfall, gale wind and storm surge 4 to 5 days in advance.

the power cut, it had come down to 1,300MWLosses across Odisha amounted to 42.4 billion rupees

JharkhandA rainfall total of 74.6 mm (2.94 in) was recorded at Ranchi, while Jamshedpur

recorded 52.4 mm (2.06 in), and Bokaro recorded 58.4 mm (2.30 in).Most of the small rivers of Ranchi like Harmu River, Jumar River, Potpoto

River, River flowing under the Over bridge etc. were overflowing due to heavy rain in the city. Even many of the local ponds were overflowing. Trees were uprooted and low land area faced water logging.

Barring an early morning lightning strike at Simdradhao village in Giridih district in which a person was killed,

according to police, there were no reports of rain-related casualty anywhere in the state.

At least 400 huts were destroyed .

15


Andaman and Nicobar IslandsOn October 8th IMD warned that heavy to very heavy rainfall would occur

over the islands while some damage to thatched huts, power and communication lines was expected.

These warnings were continued until October 11, when the IMD noted that no further adverse weather, would occur over the Andaman and Nicobar Islands.

Within the islands the Directorate of Health Services opened a Medical Camp in Rangat while the Deputy Commissioner, Police and Fire Services all ensured there were no casualties between October 8–10th .

16


Other Indian statesThe areas of West Bengal, Chhattisgarh, Bihar and eastern parts of Uttar

Pradesh are likely to experience heavy rainfall and strong winds.There is risk of trees falling and disruption of light or electricity poles.

However, the effect here will not be as severe as that in Odisha and Andhra Pradesh.

A Merchant Ship MV Bingo was feared to have sunk in rough seas off the coast of West Bengal due to Cyclone Phailin. The crew of 20 were spotted in lifeboats by the Coast Guard and were rescued.

17


NepalThe eastern region of Nepal experienced heavy rainfall and winds

while it was lighter in the central and western part of the country.

Rainfall began in the eastern and mid-western region since early

morning on 13 October and began in the central regional too in the

afternoon . The impact of the cyclone continued until 15 October.

Nepalese great festival Dashain was affected by the October rain.

It caused flood in Kosi and Gandaki rivers in Nepal

Mitigation and Relief

19


OdishaGovernment had made arrangements for over 10,00,560 food packets for

relief.Indian Air Force helicopters were kept on standby in West Bengal to

move in for help at short notice. A total of 11,54,725 people were evacuated in the wake of the storm and

the following floods in the stateInternational Medical Corps was among the first responders after Phailin,

with field workers in the affected areas within 24 hours. In partnership with the Chief District Medical Officers and local health authorities, International Medical Corps’ Emergency Response Team deployed .

20


OdishaThe creation of the National Disaster Response Force (NDRF) in 2006

ensured that there were around 2,300 personnel, especially trained in disaster mitigation and response, available for deployment, along with equipment like inflatable boads, lifebuoys and power saws.

Incidentally, Odisha had set up its own Odisha State Disaster Management Authority and Odisha Disaster Rapid Action Force (ODRAF) soon the 1999 disaster, much before the NDMA and NDRF came into being.

Apart from 2,000 personnel from the Army, the National Disaster Response Force (NDRF) has deployed 2,300 personnel in the three States – 29 teams in Odisha, 19 teams in Andhra Pradesh and 7 teams in West Bengal.

21


OdishaThe locations were identified through a scientific survey conducted by Indian

Institute of Technology (IIT), Kharagpur with two major postulates i.e. No person will have to travel more than 2.25 km to get a safe shelter and without crossing a natural Barrier. The building is designed to withstand wind speed up to 300 kmph and moderate earthquakes. Its plinth is above High Flood line (HFL) and standing on a stilted floor, it can remain unaffected in storm surge up to the 1st floor level.

So far, 203 multipurpose cyclone shelters, including 65 by Indian Red Cross Society have been constructed in coastal districts of Orissa and have been handed over to the community based Cyclone Shelter Management and Maintenance Committees (CSMMC). 52 flood shelters of similar design are being constructed in 9 flood prone districts out of Chief Minister’s Relief Fund.

CM of Odisha Mr. Naveen Pattanaik was honored by UNO

Biggest evacuation ever in india since last 23 years.

Announcement of 100 new multipurpose cyclone shelter on the occasion of 80th year completion of independent Odisha state by CM.

24


ANDHRA PRADESH

The Andhra Pradesh government and the Chief Minister met representatives of the Army and Navy seeking their assistance if required.

Utility workers striking against the division of Andhra Pradesh called off their strike partly in view of the cyclone threat to the coastal districts.

The state government ordered the evacuation of 64,000 people living in low-lying areas.

The coastal districts of the state escaped the force of the cyclone.
