The India Meteorological Department (IMD) regularly issues color-coded weather alerts during the monsoon season to inform the public and ensure preparedness for varying and potentially hazardous weather conditions.
These alerts are designed to provide timely and clear warnings about the intensity of rainfall, storms, and other adverse weather events. By categorizing alerts into different color codes, the IMD helps individuals, communities, and authorities assess the level of risk and take appropriate safety measures.
This system enhances awareness and enables more effective response strategies to safeguard lives, property, and infrastructure during the unpredictable monsoon period.

Why Are Color Codes Used?
The IMD’s color-coded weather alert system is designed to empower individuals to make informed decisions during the monsoon season. By understanding the significance of each color code and its associated risks, citizens can better prepare for adverse weather conditions and minimize the impact of potential disruptions.
What Do the Colour Codes Mean?
The IMD’s colour-coded system categorizes weather risks into four levels: green, yellow, orange, and red. Each color indicates a progressively higher level of potential risk associated with the weather.
Green Alert (No Advisory): This signifies normal weather conditions, with minimal rainfall. During the monsoon season, a green alert indicates light, scattered showers or dry weather, posing little to no risk.
Yellow Alert (Be Aware): A yellow alert signals the possibility of moderate rainfall. While not severe, it could lead to localized flooding in low-lying areas or disrupt outdoor activities.
Orange Alert (Be Prepared): An orange alert is issued when heavy rainfall of 115.6 mm to 204.4 mm is expected within 24 hours. This level of rainfall heightens the risk of flooding in streets, streams, and low-lying areas, along with potential disruptions to transportation, power outages, and landslides.
Red Alert (Take Action): The most critical category, a red alert indicates extremely heavy rainfall exceeding 204.5 mm within 24 hours. This poses a serious threat to life and property, with widespread flooding, disruption of essential services, and the likelihood of evacuation orders.
Meaning of Red, Orange, Yellow, and Green Alerts
The IMD’s colour-coded weather alerts provide essential information regarding varying levels of weather risk. Each alert corresponds to a specific severity, helping individuals make informed decisions and take appropriate actions.
Red Alert: The highest level of warning, indicating extremely severe weather conditions. It signifies heavy rainfall exceeding 204.5 mm within 24 hours, posing a significant threat to life, property, and infrastructure. Widespread flooding, disruption of essential services, and evacuation measures are likely.
Orange Alert: Issued when heavy rainfall between 115.6 mm and 204.4 mm is expected within a 24-hour period. This alert signals an increased risk of flooding, transportation disruptions, and landslides, urging individuals to be prepared for adverse conditions.
Yellow Alert: This indicates the possibility of moderate rainfall, which may cause localized flooding or disrupt outdoor activities. While not severe, it serves as a precautionary measure, advising people to stay aware and take necessary precautions.
Green Alert: The lowest level, signifying normal weather conditions with minimal rainfall. During the monsoon, a green alert indicates light scattered showers or dry weather, posing no significant risk or disruption.
