## Policy Summary: Enhancements in Early Warning Systems for Natural Disasters in India
This policy outlines the advancements made by the India Meteorological Department (IMD) and the Central Water Commission (CWC) in providing timely and accurate early warning systems for natural disasters across India, specifically addressing heavy rainfall events, floods, and cyclones in states like Gujarat, Odisha, and Kerala. The focus is on improvements in forecasting, dissemination, and impact-based warnings to minimize human and economic losses.
**Key Highlights:**
* **Improved Forecasting Accuracy:** The IMD has significantly improved the accuracy of forecasts for severe weather events like cyclones and heavy rainfall. Cyclone track forecast errors have reduced by 10-15% up to 72-hour lead time and 25-30% beyond that compared to 2015-2019. Intensity forecast errors have improved by 33-35% up to 72 hours. Landfall point error has improved by 64-72% up to 96 hours. The Probability of Detection (POD) for southwest monsoon heavy rainfall warnings has increased to 80% for day 1, 70% for day 2, and 65% for day 3 by 2024, compared to 50%, 48%, and 37% respectively in 2014. The lead period of forecasts has increased by 4 days since 2020. The forecast skill has improved by 30, 40, and 45% for 24, 48, and 72-hour lead periods, respectively, in the recent 5 years (2020-2024) as compared to the previous 5 years (2015-2019).
* **Advanced Dissemination Systems:** IMD utilizes a multi-platform dissemination system, including social media, Sachet Apps (via Common Alert Protocol - CAP), mobile apps (Mausam, Meghdoot, Damini, RAIN ALARM), WhatsApp, and APIs, to share severe weather information and early warnings with disaster management authorities and the public. The CWC has developed the 'Flood Watch India' mobile application (version 2.0) to disseminate real-time flood information and forecasts up to 7 days.
* **Impact-Based Forecasting:** IMD is transitioning to sector-specific color-coded Impact Based Forecast (IBF) and risk-based warnings (RBW) up to the district/sub-city levels, incorporating a dynamic impact and risk matrix.
* **Technological Upgrades:** The policy highlights investments in strengthening observing systems with AWS, ARG, and DWR installations; improving data integration and GIS-based DSS; enhancing NWP and climate models; and increasing computational power through supercomputers Arka and Arunika.
* **Panchayat-Level Weather Forecasting:** The Gram Panchayat Level Weather Forecasting (GPLWF) program, implemented by the Ministry of Panchayati Raj (MoPR), provides weather forecasts for nearly all Gram Panchayats in India, accessible through digital platforms like eGramswaraj, Meri Panchayat app, eManchitra of MoPR, and Mausamgram of the IMD.
* **Climate Hazard Vulnerability Atlas:** IMD has developed a web-based online "Climate Hazard Vulnerability Atlas of India" for the thirteen most hazardous meteorological events. It can be accessed at https://imdpune.gov.in/hazardatlas/abouthazard.html.

PARLIAMENT QUESTION:EARLY WARNING
SYSTEMS FOR NATURAL DISASTERS
Posted On: 23 JUL 2025 3:34PM by PIB Delhi
There has been no delay in disseminating early warning information by the India Meteorological Department
(IMD) regarding various natural disasters, including heavy rainfall events, floods, and cyclones, in States such
as Gujarat, Odisha, and Kerala. The IMD has consistently issued timely alerts and forecasts to the public and
concerned stakeholders. The Central Water Commission (CWC) is mandated to issue short-range flood
forecasts with a lead time of up to 24 hours to concerned State Governments at identified locations. Timely
flood forecasts are being issued when a certain threshold limit is reached.
IMD follows standard global best practice and operating procedures to deliver effective and efficient weather
and climate forecasting services to the nation. The skill of the operational forecasts issued by IMD for various
extreme weather and climate events is comparable to other national meteorological services of developed
countries in the world. Overall, there has been significant improvement in the forecasting of various severe
weather events like cyclones and heavy rainfall over the country during recent years (details about the IMD
forecast accuracy are given in Annexure-1).
IMD uses a state-of-the-art dissemination system to share all severe weather information and early warning
with Disaster Management Authorities as well as the general public through various platforms for necessary
preparedness and to support mitigation measures. It includes Social media, Sachet-Apps via Common Alert
Protocol (CAP), Mobile Apps, WhatsApp, and API. As a result, the vulnerable population gets evacuated
from the damage-prone areas in a timely manner to safe shelters, thereby reducing the human death toll to a
bare minimum. For this, IMD is issuing a seamless forecasting system at seasonal to nowcast scale and has
implemented a well-defined Standard Operation Procedure for monitoring & forecasting the weather hazards
and issuing impact-based warnings in consultation with NDMA, SDMA, and other various user agencies like
Aviation, power, Railways, etc.
IMD has adopted new techniques and technology from time to time to detect, monitor, and provide timely
early warnings (for the entire country, including coastal and rural communities) for all types of extreme
weather events like cyclones, floods, and heatwaves, which have devastating impacts on human lives,
livelihoods, and infrastructure. There has been significant progress in this direction with:
Strengthening of the observing system with installation of additional AWS, ARG, and DWR, etc.

Recently, a new Central Sector Scheme, "Mission Mausam," was launched by MoES with the goal of making
Bharat a "Weather-ready and climate-smart" nation.
th
Bharat Forecast System (BhartFS) was launched very recently (on 26 May 2025). The validation of the
accuracy of forecasts from BhartFS for real-time situations is yet to be carried out, as it needs data of a longer
period.
To ensure effective dissemination of warnings to vulnerable populations, various steps have been taken.
IMD's weather information including alerts and warning to the public are provided through various
platforms:
Mass Media: Radio/TV, Newspaper network (AM, FM, Community Radio, Private TV), Prasar
(cid:108)
Bharati, and private broadcasters
Weekly & Daily Weather Video

Last year (2024), a joint collaborative programme of the Central and State Governments was launched by the
Ministry of Panchayati Raj (MoPR). Under this program, the MoPR implemented the Gram Panchayat-Level
th
Weather Forecasting (GPLWF) for nearly all Gram Panchayats in India on 24 October 2024. These forecasts
are accessible on digital platforms such as e-Gramswaraj (https://egramswaraj.gov.in/), the Meri panchayat
app, e-Manchitra of MoPR, and Mausamgram of the IMD (https://mausamgram.imd.gov.in/).The main aims
and objectives of the GPLWF are to provide weather forecasts up to Gram Panchayat Levels, covering critical
parameters such as temperature, rainfall, humidity, wind, and cloud conditions—essential data that farmers
need for informed decision-making regarding sowing, harvesting, and irrigation. The platform makes weather
forecast information accessible anytime and anywhere at the panchayat level across the country. Attempts
have been made to reach a larger number of people for this weather information through Pashu Sakhis and
Krishi Sakhis under the Ministry of Agriculture and Farmers Welfare and the Ministry of Rural Development.
IMD has also brought out a web-based online "Climate Hazard & Vulnerability Atlas of India" prepared for
the thirteen most hazardous meteorological events, which cause extensive damage and economic, human, and
animal losses. The same can be accessed at https://imdpune.gov.in/hazardatlas/abouthazard.html. This atlas
will help State Government authorities and disaster management agencies identify the hotspots and plan and
take appropriate action to tackle extreme weather events. This product is helpful in building Climate Change
resilient infrastructure.
IMD has launched seven of its services (Current Weather, Nowcast, City Forecast, Rainfall Information,
Tourism Forecast, Warnings, and Cyclone) with the 'UMANG' Mobile App for use by the Public. Moreover,
IMD developed a mobile App, 'MAUSAM' for weather forecasting, 'Meghdoot' for Agromet advisory
dissemination, and 'Damini' for lightning alerts. The Common Alert Protocol (CAP), developed by the
NDMA, is also being implemented to disseminate warnings by the IMD.
The CWC has taken several steps by adopting various dissemination mechanisms to get maximum reach tothe flood warnings, so that mitigation measures can be adopted by State Governments, SDMA, NDMA, and
the public. Further, with an aim of disseminating information related to the flood situation in the country and
flood forecasts up to 7 days on a real-time basis to the public through mobile phones, version 2.0 of the 'Flood
Watch India' mobile application has been developed by the CWC, which provides current information on
flood conditions across the country. Further, it also provides additional information regarding the storage
positions of 150 major reservoirs in the country, which helps in a better understanding of the possible flood
situation in their downstream areas. The 'Flood Watch India' app is available for download.
