1. Look Beyond the Daily Forecast
A simple “rainy” icon on your phone isn't enough. Before you leave, check the multi-day forecast from a reliable source like the India Meteorological Department (IMD). Use their official 'MAUSAM' app to understand the bigger weather pattern. Look for terms
like “widespread rain” or an active “low-pressure area” along your route, which suggest persistent and heavy spells rather than just passing showers. This extended forecast helps you decide if postponing the trip by a day or two might offer a safer travel window.
2. Decode Rainfall Intensity Warnings
Not all rain is equal. The IMD uses specific colour codes and terms to warn about rainfall intensity. A 'green' or 'yellow' alert might be manageable, but an 'orange' or 'red' alert signals a high probability of heavy to extremely heavy rainfall that can cause major disruptions. These intense spells lead to poor visibility, dramatically increased braking distances, and a higher risk of accidents. Check the IMD’s city or district-specific warnings for alerts on “heavy to very heavy rainfall,” and reconsider your travel plans if a red alert is issued for your route or destination.
3. Assess Landslide and Flash Flood Risk
If your route passes through hilly terrain or ghat sections, checking for landslide risk is non-negotiable. Heavy rain saturates soil, making slopes unstable. The Geological Survey of India (GSI) is the nodal agency for landslide studies, and their data informs official warnings. Use the NDMA's 'SACHET' app for disaster warnings, which can include advisories for landslides. Also, check for flash flood warnings, especially in low-lying areas or regions with multiple river crossings. Even a few inches of fast-moving water can sweep a vehicle away. If authorities advise against travel in hilly areas, heed the warning.
4. Monitor Wind Speed and Gusts
High winds are an often-underestimated monsoon hazard. They can be particularly dangerous on open highways, bridges, and when passing larger vehicles like trucks and buses. Strong gusts can affect your vehicle's stability and push it out of its lane. Weather apps and IMD bulletins often provide forecasts for wind speed, sometimes with warnings for “gusty winds” reaching 40-50 kmph or more during thunderstorms. If high winds are predicted, it's crucial to reduce your speed, maintain a firm grip on the steering wheel, and keep a safe distance from other vehicles.
5. Check for Real-Time Waterlogging
A national weather forecast won't tell you if a specific underpass on your route is flooded. This is where real-time traffic and local information become vital. Before and during your drive, use apps like Google Maps or Mappls to check for road closures and traffic slowdowns, which often indicate waterlogging. Local social media groups and radio channels are also excellent sources for on-the-ground updates. Never attempt to drive through a flooded road if you can't see the pavement; the water is often deeper than it appears and can stall your engine or sweep your vehicle away.
6. Track Thunderstorms and Lightning
Monsoon storms are frequently accompanied by lightning. While your car offers some protection, it's not a good idea to be driving through an intense thunderstorm. Apps from the IMD like 'Damini' are specifically designed to provide lightning alerts for your location, often warning you if strikes are likely within a 20-40 km radius. Other apps like Skymet Weather also provide lightning status updates. If a severe thunderstorm is in your immediate path, the safest option is to pull over in a secure, covered location (not under a lone tree) and wait for the worst of it to pass.
7. Evaluate Visibility Conditions
Heavy rain, mist, and fog can drastically reduce visibility, sometimes to just a few feet. This is one of the biggest dangers of monsoon driving. While forecasts might mention 'fog' or 'mist', the real impact depends on local conditions. Before driving into a hilly or coastal area known for fog, check local reports. Always use your low-beam headlights in rain or fog to be more visible to other drivers—it's the law in many places. If visibility becomes so poor that you can't see the edges of the road or other vehicles clearly, pull over safely and wait for conditions to improve.
