Start with Digital Forecasts
Before you even pack the car, your first step should be a thorough digital check. The India Meteorological Department (IMD) is the most reliable source for official weather warnings, including alerts for heavy rainfall, thunderstorms, and potential landslides
in hilly areas. The IMD's website and its 'Mausam' app provide district-level forecasts and nowcasts, which are short-term predictions for the next few hours. Look for specific alerts like heavy rain warnings or news of low-pressure systems forming, which often intensify monsoon activity. Also, check travel advisories from local authorities, as they will have the most current information on road closures or diversions due to weather.
Learn to Read the Clouds
The sky offers some of the best clues about impending weather. Dark, heavy-looking clouds are an obvious sign of rain, but knowing the types can help you predict its intensity and duration. Flat, grey, sheet-like clouds are called stratus clouds, and they typically bring light, steady drizzle. However, if they thicken and darken into nimbostratus clouds, expect prolonged and more significant rainfall. The most dramatic are cumulonimbus clouds—the tall, towering, anvil-shaped giants. These are thunderstorm clouds and are associated with heavy downpours, strong winds, and lightning. If you see these building up, it’s a sign that severe weather is likely approaching. The direction and speed of cloud movement also matter; fast-moving clouds often indicate strong winds and an approaching storm system.
Observe Your Immediate Environment
The environment around you provides subtle but valuable weather hints. A sudden drop in temperature and a noticeable increase in humidity often precede a downpour. Pay attention to the wind; if it picks up suddenly and begins blowing in strong gusts, a storm is likely near. Another telling sign is the ground itself. If the soil is already spongy or you see water pooling in areas that normally drain well, it means the ground is saturated. Any further rain will immediately become runoff, increasing the risk of localised waterlogging and flash floods. Unusual sounds, like a distant, steady roar, could even indicate a flash flood approaching in hilly or canyon areas.
On-the-Road Weather Indicators
Once you are driving, stay vigilant for changing conditions. The most immediate challenge in a downpour is reduced visibility. If you can barely see the taillights of the car ahead, conditions are unsafe. Use your low-beam headlights—not high beams, which reflect off raindrops and worsen visibility—to see and be seen. Wet roads dramatically increase braking distance and the risk of hydroplaning, where your tyres lose contact with the road surface. Reducing your speed is crucial. If you see water beginning to flow across the road or notice debris like branches in the water, it's a major red flag that the flow is stronger than it appears. Never attempt to drive through waterlogged streets; it takes surprisingly little moving water to carry a vehicle away, and you can't be sure of the water's depth or the road's condition underneath.
Essential Pre-Drive Vehicle Checks
Your car is your first line of defence. Before any monsoon trip, ensure your vehicle is ready for the challenge. Check that your tyres have adequate tread depth to displace water and prevent hydroplaning. Worn tyres are a significant risk on wet roads. Your windscreen wipers must be in excellent condition to maintain visibility; replace them if they leave streaks. Test your brakes, as wet conditions can affect their performance. Finally, ensure all your lights—headlights, taillights, and hazard lights—are working correctly. Keeping an emergency kit with a torch, first-aid supplies, and extra water is also a wise precaution for any long drive during this season.
