A new technology,‘ Impact Based Forecasting Approach’, has been developed to assess the rise in water level in rivers and reservoirs due to rain and can help State governments to minutely monitor the impact of rainfall.The new technology   shows “pre-event scenario” can help authorities in taking real-time decisions.It will help in generating a scenario where authorities can take decisions to release water or not.

                                The heavy downpour that ravaged Kerala for a fortnight ending August 21 caused death of around 500 people and economic damage of over ₹40,000 crore.

  • There is a need of  “deliberately for drainage” to prevent disasters like Kerala floods.
  • Every river, pond, paddy field and city should be mapped and protected.
  • Every home, institution, village and city must be required to do rainwater harvesting so that rain can be channelised and recharged.

                         The India Meteorological Department (IMD)  issues four colour codes to indicate various categories of alerts. Here is what each alert means:

Green (All is well): No advisory is issued

Yellow (Be aware): Severely bad weather is possible over the next few days, plan ahead thinking about possible travel delays and disruption of day-to-day activities possible. It indicates the weather may change or worsen in the next few days.

Amber (Be prepared): There is an increased likelihood of extremely bad weather, which could potentially cause travel delays, road and rail closures, and interruption of power supply. There could be risk to life and property. Amber means people need to be prepared to change plans and protect themselves, their family and community from the impacts of the severe weather based on the forecast from the Met Office.

Red (Take action): Extremely bad weather is expected. People need to take action to keep themselves and others safe. Widespread damage, travel and power disruption and risk to life are likely. People must avoid dangerous areas and follow the advice of the emergency services and local authorities.
