Explained: What Do Red, Orange, Yellow And Green Weather Alerts Issued By IMD Mean
During the monsoon, these alerts are particularly crucial for understanding the intensity of rainfall.
India Meteorological Department (IMD) issues colour-coded weather alerts from time to time during the monsoon to keep citizens informed and prepared in times of unpredictable and potentially unfavourable weather conditions.
Why Are Colour Codes Used?
The IMD's colour-coded weather alert system helps people make informed decisions during the monsoon. By understanding the different colour codes and their risks, people can navigate the monsoon season with greater preparedness and minimise the impact of potential weather disruptions.
What Colour Codes Mean?
The IMD's colour-coded system utilises four distinct categories: green, yellow, orange, and red. Each colour represents a higher level of potential risk associated with the weather.
Green Alert (No Advisory): This signifies normal weather conditions with minimal rainfall. During the monsoon, a green alert indicates light scattered showers or dry weather.
Yellow Alert (Be Aware): A yellow alert suggests the possibility of moderate rainfall. While not severe, it might cause localised flooding in low-lying areas or disrupt outdoor activities.
Orange Alert (Be Prepared): When the IMD forecasts heavy rainfall exceeding 115.6 mm and up to 204.4 mm within 24 hours, an orange alert is issued. This signifies a heightened risk of flooding in streets, streams, and low-lying areas. Disruptions to transportation, power outages, and landslides become possibilities.
Red Alert (Take Action): The most severe category, a red alert indicates extremely heavy rainfall exceeding 204.5 mm within 24 hours. This poses a significant threat to life and property. Widespread flooding, disruption of essential services, and evacuation orders become likely.
Meaning Of Red Alert, Orange Alert And Yellow Alert
During the monsoon, these alerts are particularly crucial for understanding the intensity of rainfall. Here's a breakdown of how the colour codes translate to monsoon situations:
Green: Light showers or dry weather, perfect for outdoor activities.
Yellow: Moderate rainfall, be cautious in low-lying areas and carry an umbrella.
Orange: Heavy rainfall, stay indoors if possible, stock up on essentials, and be prepared for any potential disruptions.
Red: Extremely heavy rainfall, evacuate if instructed, avoid travel, and prioritise safety.
