Your Official Weather Source
In India, the primary agency for all things weather-related is the India Meteorological Department (IMD). Established in 1875, the IMD is the government body responsible for meteorological observations, weather forecasting, and issuing warnings for severe
weather phenomena like cyclones, heavy rain, and heatwaves. When you see weather alerts in the news or on apps, they are almost always based on data and forecasts provided by the IMD. The department uses a clear, colour-coded system to help the public quickly understand the severity of expected weather. This system is designed to turn complex data into simple, actionable advice.
Decoding the Colour-Coded Alerts
The IMD uses four main colours to communicate weather warnings: Green, Yellow, Orange, and Red. Each represents a different level of intensity and required action. A Green alert means 'All is Well', indicating no significant weather threat and no advisory is needed. A Yellow alert means 'Be Aware'; it signals that weather could change for the worse and might disrupt daily activities. An Orange alert is a call to 'Be Prepared' for extremely bad weather that has the potential to disrupt transport and power. The highest level, a Red alert, means 'Take Action', signifying that severe conditions are expected, posing a significant risk to life and property.
Yellow Alert: Plan for Delays
A Yellow alert is the most common warning during an active monsoon. It signifies a 'Watch' or 'Be Aware' status. For city travel, this means you should expect moderate rainfall. While not typically severe, this level of rain can cause waterlogging in low-lying areas and create traffic congestion. If a Yellow alert is active, it’s wise to add extra buffer time to your commute. Check real-time traffic updates before you leave and be mentally prepared for a slower journey. It’s a heads-up to stay updated and exercise caution, but not necessarily to cancel your plans.
Orange Alert: Reconsider Your Travel
When an Orange alert is issued, it means 'Be Prepared'. This indicates a forecast of heavy to very heavy rainfall, typically between 115.6 mm and 204.4 mm in a 24-hour period. For a city resident, this is a serious warning. The risk of widespread waterlogging, street flooding, major traffic disruptions, and power outages is high. Non-essential travel should be reconsidered or postponed. If you must travel, ensure your phone is fully charged, inform someone of your route, and prepare for significant delays. Authorities are expected to be on high alert to handle potential emergencies.
Red Alert: Prioritise Safety Above All
A Red alert is the most severe warning and means 'Take Action'. It is issued when extremely heavy rainfall (over 204.5 mm in 24 hours) is forecast, posing a significant threat to life and property. During a Red alert, citizens are advised to stay indoors and avoid all travel unless absolutely essential or instructed to evacuate. Widespread flooding, collapse of weak structures, and total disruption of transport and power are highly likely. Your personal safety becomes the top priority. Following instructions from local disaster management authorities is crucial during such events.
Practical Tips for Monsoon Commuting
Regardless of the alert colour, monsoon travel in the city requires preparation. Before the season begins, ensure your vehicle's tyres, brakes, and wipers are in good condition. When it rains, drive slowly as roads become slippery. For pedestrians, wearing anti-slip footwear is essential to navigate wet and uneven pavements. It's always a good idea to carry a waterproof bag for your electronic devices like phones and laptops. Avoid walking through flooded streets, as there could be open manholes or other hidden dangers. If a downpour is exceptionally heavy, it is always safest to wait it out in a secure location rather than rushing through hazardous conditions.
