Your Most Reliable Source
When planning any travel during India's monsoon season, your first and most reliable source should be the India Meteorological Department (IMD). As the country's principal government agency for meteorology, the IMD provides the most accurate forecasts
and warnings. You can access its services through the official website (mausam.imd.gov.in) or by using its dedicated mobile apps, such as 'Mausam'. These tools are designed to communicate weather information clearly, helping you plan ahead and stay safe.
Decoding the Colour Codes: Green and Yellow
The IMD uses a simple colour-coded system to alert the public about the severity of expected weather. A 'Green' alert means 'All is Well'. This indicates normal weather conditions with no significant threat expected, so you can proceed with your travel plans without any weather-related concerns. A 'Yellow' alert means 'Be Aware'. This signals that weather conditions might change for the worse over the next few days, with a possibility of moderate rainfall or other disturbances. For a traveller, a yellow alert is a prompt to stay updated and check forecasts frequently, as your daily activities could be disrupted.
When Plans Should Change: Orange and Red
An 'Orange' alert means 'Be Prepared'. This is a serious warning for extremely bad weather that has a high likelihood of disrupting travel, with potential for road closures, power cuts, and other hazards like landslides. If your destination is under an orange alert, you should be ready to alter your plans significantly and stock up on essentials. The highest level is a 'Red' alert, which means 'Take Action'. This is issued for extremely severe weather conditions, such as exceptionally heavy rainfall, that pose a significant threat to life and property. Authorities may issue evacuation orders, and travel should be avoided entirely in areas under a red alert.
What 'Heavy Rainfall' Actually Means
Beyond the colours, the IMD uses specific terms to classify rainfall intensity over a 24-hour period. Understanding these can give you a clearer picture of what to expect. 'Heavy Rainfall' is defined as 64.5 mm to 115.5 mm. 'Very Heavy Rainfall' indicates a downpour between 115.6 mm and 204.4 mm. Anything above 204.5 mm is classified as 'Extremely Heavy Rainfall'. These measurements are crucial because higher volumes of rain dramatically increase the risk of flash floods and landslides, especially in hilly or coastal regions.
Practical Tips for the Prudent Traveller
Reading the forecast is the first step; acting on it is the next. If you see warnings for heavy rain, especially orange or red alerts, reconsider your travel dates or destination. Always build buffer days into your itinerary to account for potential delays from road closures or cancelled flights and trains. Pack appropriately with waterproof bags, quick-drying clothes, and sturdy, non-slip footwear. Before heading out, especially on a road trip, check local traffic police social media handles and district disaster management websites for real-time updates on road conditions. And always inform your family or friends of your detailed itinerary.
