The India Meteorological Department (IMD) has stated that cyclone Pabuk will move northwestwards and cross the Andaman Islands late on 6th Jan as a cyclonic storm with wind speed up to 90 kmph. IMD has sounded a orange alert for the cyclone Pabuk. The Pabuk cyclone would cause heavy rain over the Andaman Islands.
Cyclone Pabuk originated over the Gulf of Thailand and neighbourhood. The IMD predicts that Pabuk would move west-northwestwards and emerge into the Andaman Sea. Then it would move northwestwards and cross the Andaman Islands. Then recurve northeastwards towards Myanmar coast and weaken gradually.
The four stages of cyclone warnings in India are:
- The First Stagewarning Pre Cyclone Watch, issued 72 hours in advance. It contains an early warning about the development of a cyclonic disturbance in the north Indian Ocean, its likely intensification into a tropical cyclone and the coastal belt likely to experience adverse weather.
- The second stage warning is Cyclone Alert, is issued at least 48 hrs in advance of the expected commencement of adverse weather over the coastal areas. It contains information about the location and intensity of the storm likely direction of its movement, intensification, coastal districts likely to experience adverse weather and advice to fishermen, the general public, media and disaster managers.

- The Third Stage warning is Cyclone Warning, issued at least 24 hours in advance of the expected commencement of adverse weather over the coastal areas and the landfall point is forecasted at this stage.
- The Fourth Stage of warning is Post Landfall Outlook and it gives likely direction of movement of the cyclone after its landfall and adverse weather likely to be experienced in the interior areas.
Even though there is no cyclonic situation for Odisha, Seven districts of Odisha have been put on alert and the weather in Odisha would be cloudy and dry.
India Meteorological Department (IMD) has developed new technology called ‘Impact Based Forecasting Approach’ to assess rise of water level in rivers and reservoirs by rain. It shows pre-event scenario will help state governments authorities to minutely monitor impact of rainfall and take real-time decisions. It will help to avoid disastrous situation similar to Kerala floods. It can generate scenario to help take decisions to release water or not from reservoirs after heavy downpour. It will be helpful for every state authority to take decision. This system can be run in pre-event scenario.
The heavy downpour which had ravaged Kerala in August 2018 had caused death of around 500 people and economic damages worth over Rs 40,000 crore. Excessive rainfall had led to floods in Kerala and was result of climate change. State Government had blamed IMD for lapses in its part for wrong rain forecast. IMD had forecasted estimated 98.5 mm rain in the state between 9 and 15 August, 2018 but Kerala received was 352.2 mm of rainfall resulting in severe flooding.

- Undertake meteorological observations and provide current information and forecasting information for most favorable operation of weather-dependent activities such as irrigation, agriculture, aviation, shipping etc.
- Offer warning against severe weather phenomenon such as tropical cyclones, norwesters, dust storms, heat waves, cold waves, heavy rains, heavy snow, etc.
- Provide met-related statistics needed for agriculture, industries, water resources management, oil exploration, and any other strategically important activities for the country.
- Engage in research in meteorology and allied subjects.
- Detect and locate earthquakes and evaluate of seismicity in various parts of the country for developmental projects.
