Decoding the IMD's Colour System
The IMD's alerts are designed to simplify complex weather data into straightforward advice. The system uses four colours—Green, Yellow, Orange, and Red—to signal the expected intensity of a weather event and its potential impact on daily life. For commuters,
understanding these colours is key to making safe and smart travel decisions, as they apply not just to rain but also to thunderstorms, cyclones, and other hazardous weather. The goal is to help people prepare for everything from minor delays to significant disruptions.
Green Alert: All Is Well
A Green alert means normal weather conditions are expected. For commuters, this is a signal that no specific precautions are necessary. While there might be light, sporadic showers, significant travel disruptions are not anticipated. You can proceed with your daily travel plans without worrying about major weather-related delays or dangers. It essentially means "all is well," and no advisories are in effect.
Yellow Alert: Be Aware
When a Yellow alert is issued, it's a call to "be aware" or "watch". This indicates that weather conditions could worsen and there is a possibility of heavy rain that might disrupt daily activities. For commuters, this is a sign to stay updated on forecasts. You may face minor traffic snags or localised waterlogging in low-lying areas. It is wise to allow for some extra travel time, carry an umbrella or raincoat, and check your route for any reported issues before you leave.
Orange Alert: Be Prepared
An Orange alert signals a higher level of warning, urging you to "be prepared" for potentially disruptive weather. This is typically issued when heavy to very heavy rainfall is expected, which can lead to significant problems like traffic congestion, waterlogged streets, and delays on road and rail networks. Power outages are also a possibility. Commuters should seriously consider whether their journey is necessary. If you must travel, be extremely cautious and prepare for substantial delays.
Red Alert: Take Action
A Red alert is the highest and most urgent warning, meaning you need to "take action". It is issued when extremely severe weather is imminent, posing a significant risk to life and property. This could involve extremely heavy rainfall leading to widespread flooding, major infrastructure damage, and the failure of transport services. Commuters are strongly advised to avoid travel unless it is absolutely essential and to follow all instructions from local authorities, which may include evacuation orders from vulnerable areas. Prioritising safety is paramount during a red alert.
Practical Commuting Tips for Any Alert
Regardless of the colour code, a little preparation makes any monsoon commute safer. Before leaving, always check the latest weather updates and traffic advisories. Reduce your speed while driving on wet roads and maintain a safe distance from other vehicles. Ensure your phone is fully charged and consider carrying a power bank, as delays can be unpredictable. Keeping essentials like drinking water, snacks, and a small first-aid kit in your bag is also a good practice. Finally, never attempt to drive or walk through waterlogged streets where the depth is unclear, as hidden potholes or open drains pose a serious risk.
