During North East Monsoon period there is absolute possibility of heavy rains resulting in inundation, floods etc. The depressions in the Bay of Bengal may intensify into Cyclonic Storms. The three months period [i.e.October December] categorized as ‘PERIOD OF ALERT’. The last two weeks of November and the first week of December will be the ‘CRUCIAL PERIOD OF ALERT’.

The rains may cause heavy inflow of water in the rivers and jungle streams, odais etc. These water courses then become too narrow to carry large volume of water which flows. Therefore the water overflows thereby breaching embankments, causes enormous damages to houses, huts, agricultural lands, roads, telephone lines, railway tracks, electricity lines and other public properties. It is not feasible to completely prevent nature’s fury at one stroke. However, to minimize the damage caused by nature’s onslaught and to ensure speedy relief thereby mitigating the sufferings of the people, the Dindigul District Administration have to devise a plan and prepared a comprehensive ‘DISASTER MANAGEMENT PLAN’. The plan can be set in motion when the need arises with the active co ordination of inter departmental officials.


Steps to be taken by public when a warning for Cyclone threatening the area is received:-

  1. Keep your T.V., Radio on and listen to latest weather warnings and advisories from the Doordharsan All India Radio station. Pass on the information to others as quickly as possible.
  2. Avoid being misled by rumours. Pass on only the official information you have got from the T.V. Radio to others.
  3. Move away from low-lying beaches or other location, which may be swept by high tides or storm waves. Leave sufficiently early before your way to high ground gets flooded.Do not delay and run the risk of being marooned.
  4. If your house is out of danger from high tides and flooding from the river and it is well built it is then probably the best place to weather the storm. However please act promptly if asked to evacuate.
  5. Be alert for high water in areas where streams of rivers may flood due to heavy rains.
  6. Bolt up glass windows or put storm shutters in place. Use good wooden blanks securely fastened provide strong suitable support for outside doors.
  7. If you do not have wooden boards handy, paste paper strips on glasses to prevent splisters flying in to the house.
  8. Get extra food, especially items which can be eaten without cooking or with very little preparation. Store extra drinking water in suitably covered vessels. Make provision for children and adults requiring special diets.
  9. If you are in one of the evacuation areas, move your valuable articles to upper floors to minimise flood damages.
  10. Have hurricane latern, flash lights and other emergency lights in working condition and keep them ready.
  11. Check on everything that might blow away or be born loose. Kerosene tins, canes, agricultural implements, garden tools, road signs and other objects become weapons of destruction in strong winds. Remove them and store them in a covered room.
  12. Be sure that a window or door can be opened on the left side of the house [i.e] the side opposite the one facing the wind.
  13. Remove cattle to safe place as faraway as possible.
  14. If the centre of eye of the storm passes directly over your place, there will be wind and rain lasting for half an hour or more. During this period stay in a safe place. Make emergency repairs during the pre monsoon period, if necessary, but remember that strong winds will return suddenly from the opposite direction, frequently with even greater velocity.
  15. Be calm your cability to meet any emergency which will inspire and help others.

Details of Two Stage Warning issued by the Area Cyclone Warning Centre [Indian Meteorological Department], Chennai.

  1. The Area Cyclone Warning Centre, Chennai [Indian Meteriological Department] will be issuing relevant Warning for Cyclone storms under the Two Stage Warning Systems, the First Stage Warning ‘CYCLONE ALERT’ is issued to the District Collectors of those coastal Districts which are expected to receive heavy rain 7.50 cm. or more in 24 hours and experience strong winds [45 km. per hour or more] in association with Cyclone in the Bay of Bengal or depressions which are expected of intensify into a Cyclonic Storm. The First Stage Warning is issued as for as possible 48 hours before the commencement of weather through high priority land line telegraphs with a copy to the Chief Secretary. The Second Stage warning is issued 24 hours prior to the commencement of expected rough weather and subsequent bulletins will be broadcast through A.I.R. Broadcasts through All India Radio Stations at Chennai, Tiruchirappalli,Kodaikanal and Pondicherry. These bulletins will be broadcast at frequent intervals by interrupting the routine programmes and will contain the latest information about the position and intensity of the storm, its motion and movements and details of expected impact of the cyclone. Where extreme weather and the possibility of storm surges are foreseen, the bulletins may also indicate areas where drastic preventive action like evacuation of people may be necessary. When the storm comes within the coverage of the coastal radars it is continuously tracked and weather bulletins on the storm are broadcast every hour from the nearest A.I.R. station where severe adverse weather would be occurring.
  2. The First Stage Warning message itself will usually contain the advice requesting Collectors to arrange listening to further warnings through All India Radio. As soon as the First Stage Warning is received, Officers should be detailed to keep in touch over the A.I.R. on 24 hours basis, preferable at the Collectorate premises. This watch should be maintained till the danger is over. If, however adverse weather condition do not develop due to the Cyclone moving, away from the area of dissipating a dewarning message would be received by Message from the Area Cyclone Warning Centre, Chennai when the listening watch could be terminated.
  3. The Collectors as Chief Coordinator of the District Organization connected with emergency and relief measures will keep a continuous check of the weather warning received. These should be transmitted to all the Revenue subordinates and other State Officials at Sub Divisions, Taluk, Block and Panchayat level through the Police W/T and through telephone wherever available .Close liaison may be maintained with the local Postal Department Officials who also may be receiving similar weather warning [upto a maximum of six warnings a day in case of cyclone storms.

A Local Committee consisting of the above Departments may be constituted before-hand which may meet at short notice on receipt of the CYCLONE ALERT. As the Officials and non-offici’ls agencies thus get alerted to be prepared for meeting danger by beat of ‘tom- tom’ and other means special care is to be taken to reach people living areas close to coast.

Bus and other transport other than those which are requisitioned for emergency and evacuation purposes which happen to be areas directly threatened by the cyclone should be asked to move out of the danger zone quickly.
  5. Railway Authorities should be kept in constant touch for knowing the service ability of the coastal line for ordering movement of emergency supplies at short notice. A review of equipment and supplies to be kept at strategic points may be made for quick restoration of transport and communication after the storm by the Public Works Department, Post and Telegraph, etc. Suitable holding [storage and located on high ground] may be chosen and earmarked in advance near coastal areas and low lying areas so that in case of flood, the public may move into these shelters for safety. Other similar action for pooling of local resources should be completed on the receipt of the First Stage Warning.
  6. On receipt of the second stage warning, the information about the time of the centre of the storm striking the coast would be disseminated to the concerned section of the public by widespread publicity like beat of tom tom etc. The people should be advised to take shelter in designated safe places. Police Wireless may be used to disseminate the warnings and safety instructions to the different areas in the District. All the Hospitals and Doctors in the areas should be alerted and emergency wards/First Aid Stations manned help of the voluntary organisations should be kept fully mobilised. People may specially advised not to leave the shelters immediately when there is a full in the wind/rain, for if the full is due to the eve of the storm passing over the area, strong winds, will return suddenly from the opposite direction.
