The Source of Truth: IMD
When it comes to weather warnings in India, the India Meteorological Department (IMD) is the official agency. The IMD's goal is to alert people and authorities about hazardous weather that could cause damage or disruption. These warnings are disseminated
through news bulletins, social media, and dedicated mobile apps, providing a crucial first step in planning your monsoon commute. Understanding these official alerts, which are based on the likelihood and potential impact of a weather event, allows you to move beyond guesswork and make informed decisions before you even step out of the door.
Decoding the Colours of the Monsoon
The IMD uses a simple colour-coded system to indicate the severity of expected weather. Knowing what each colour means is key to assessing your travel risk. A Green alert means 'All is Well', and no advisory is needed. A Yellow alert means 'Be Aware'; it signals that weather could worsen and cause some disruption to daily travel, so you should stay updated. An Orange alert means 'Be Prepared' for extremely bad weather with the potential for traffic congestion, travel delays, and even power outages. The highest level is a Red alert, which means 'Take Action'. This is issued for severe weather events that pose a significant risk to life and property, and you should avoid non-essential travel.
What the Rainfall Amounts Mean
The colour alerts for rain are tied to specific quantitative forecasts. A Yellow alert is typically issued when rainfall between 64.5 mm and 115.5 mm is expected in a 24-hour period, which can cause some waterlogging. An Orange alert corresponds to expected rainfall between 115.6 mm and 204.4 mm, increasing the chances of significant flooding and traffic disruption. A Red alert is sounded for anticipated rainfall above 204.5 mm, which carries a high risk of severe flooding and major disruptions to transport and power. These numbers give you a concrete idea of the conditions your city's infrastructure will be facing.
Your Pre-Commute Action Plan
Before you leave, translate the day's weather alert into a practical plan. On a Yellow alert day, allow for extra travel time and check your route for known waterlogging spots. If an Orange alert is issued, seriously consider if your travel is necessary; if you must commute, prepare for significant delays and have backup options ready. Remote work might be the safest and most efficient choice. On a Red alert day, the advice is clear: stay home if you can. Public transport may be suspended, and roads can become impassable or dangerous. Always prioritise your safety over reaching your destination.
Essential Apps for Your Phone
Technology is a commuter's best friend during the monsoon. The government's official 'Mausam' app provides reliable, real-time updates, forecasts, and colour-coded warnings directly from the IMD. For lightning, the 'Damini' app gives alerts for strikes in your vicinity, which is crucial for personal safety if you are outdoors. Beyond official apps, platforms like Google Maps offer real-time traffic data, which can help you navigate around flooded streets and congestion. Having these tools on hand allows you to adapt your plans on the move based on the latest information.
Practical In-Transit Safety
If you get caught in a heavy downpour while commuting, safety should be your priority. For those driving cars, reduce your speed, maintain a safe distance from the vehicle ahead, and never drive into standing water if you cannot judge its depth. For two-wheeler riders, ensuring good tyre tread and brakes is critical before the season even starts. Users of public transport should keep electronics in waterproof bags and be cautious on slippery station stairs and footbridges. A small emergency kit with a power bank, a towel, and a waterproof pouch can make unexpected delays much more manageable.
