During the monsoon season, weather forecasts frequently feature colour-coded warnings issued by the India Meteorological Department (IMD) to inform the public about expected rainfall intensity and potential risks. Understanding what red, orange, and yellow alerts signify is essential for commuters, travellers, and residents planning their daily activities.
The IMD uses this colour-coded system to share critical weather updates through bulletins, mobile applications, television, radio, and social media, enabling both citizens and local authorities to prepare in advance for severe weather conditions.

Yellow Alert: Be Aware
A yellow alert serves as the first level of warning issued by meteorological authorities. It indicates that weather conditions could potentially worsen and advises people to stay updated with the latest forecasts. While heavy rain may affect daily travel in some areas during a yellow alert, widespread disruptions are typically not expected. Commuters are generally advised to carry umbrellas or raincoats, allow extra travel time, and monitor ongoing weather updates.
Orange Alert: Be Prepared
An orange alert represents a more serious warning, indicating that heavy to very heavy rainfall is likely. This level of alert warns residents to prepare for possible disruptions such as waterlogging, traffic congestion, localised flooding, and delays to road, rail, or air travel. Residents living in low-lying areas are advised to remain cautious, while commuters should avoid unnecessary travel if conditions deteriorate. Authorities also recommend securing outdoor items and keeping emergency essentials ready.
Red Alert: Take Action
A red alert is the highest level of weather warning issued by the IMD. It is triggered when extremely heavy rainfall or severe weather is expected, carrying a significantly higher risk of flooding, property damage, and widespread disruption. During a red alert, individuals are strongly advised to avoid unnecessary travel, follow instructions issued by local authorities, and stay indoors unless travel is strictly essential. Depending on local conditions, schools, offices, and public transport services may also be suspended or heavily impacted.

Checking the latest IMD forecasts before leaving home allows individuals to avoid flooded roads, traffic bottlenecks, and hazardous travel environments. As the monsoon progresses across various parts of the country, paying close attention to these weather alerts and responding proactively helps ensure personal and community safety.
