Weather Outlook: Heavy Rain Forecast
The India Meteorological Department (IMD) has forecast the onset of the northeast monsoon around October 15, bringing a prolonged wet spell to the southern peninsula that could last for several days. Widespread heavy to very heavy rainfall is expected
across Kerala, Tamil Nadu, and south interior Karnataka between October 15 and October 20. Authorities have issued alerts for intense rainfall, thunderstorms, and gusty winds, advising residents and travellers to monitor weather updates closely. This significant weather shift follows the withdrawal of the southwest monsoon and is expected to bring much-needed rain but also heightened risks for those on the road.
Kerala: High Alert in Several Districts
Kerala is on high alert, with the IMD issuing an orange alert for very heavy rainfall in several districts, including Pathanamthitta, Kottayam, Ernakulam, and Idukki, starting October 15. Other districts are under a yellow alert. Recent heavy rains have already caused localised damage, such as a road collapse in Akkulam, Thiruvananthapuram, highlighting the vulnerability of infrastructure. Travellers should be cautious of potential waterlogging, particularly in low-lying areas like Aluva, and the risk of uprooted trees. Authorities have warned of possible disruptions to traffic due to these conditions. The mountainous regions of Idukki and Wayanad are particularly susceptible to landslides during intense rainfall.
Karnataka: Ghat Sections and Coastal Roads at Risk
In Karnataka, the focus is on the coastal districts and the Western Ghats, which are prone to landslides. Studies have previously highlighted that over 60% of the Western Ghats stretch in the state is highly susceptible to landslides, a risk compounded by hill-cutting for road expansion. The IMD has forecast fairly widespread to widespread showers for South Interior Karnataka from October 16, with heavy rain expected in coastal and north interior regions in the following days. Key ghat sections like Charmadi, Shiradi, and Sampaje are being monitored, with equipment on standby to clear any landslide debris. During previous heavy rainfall events, landslides have obstructed routes in Belthangady taluk and other areas, disrupting connectivity. Travellers using these routes should exercise extreme caution.
Tamil Nadu and Andhra Pradesh: Focus on Flooding
Tamil Nadu is bracing for the northeast monsoon, with forecasts of heavy to very heavy rainfall on October 15. In preparation, authorities in Chennai and surrounding districts were tasked with completing flood mitigation work by October 15, including desilting storm water drains. The state has identified over a thousand flood-vulnerable locations and developed response plans. For travellers, this means a high probability of waterlogged roads, especially in urban and low-lying areas. In Andhra Pradesh, isolated heavy rain is forecast for coastal districts between October 15 and 19, accompanied by strong surface winds. Key national highways could experience slowdowns or temporary closures due to inundation.
Essential Safety Advice for Travellers
Given the weather predictions, non-essential travel should be reconsidered. If travel is unavoidable, it is crucial to stay updated with the latest advisories from the IMD and local disaster management authorities. Before starting your journey, check real-time traffic updates on navigation apps for road closures or diversions. Avoid driving through waterlogged streets, as the depth can be deceptive and lead to vehicle damage or accidents. In hilly and ghat sections, be extremely vigilant for signs of landslides, such as falling debris or cracks in the road. It is advisable to avoid travel in these areas at night or during peak rainfall. Ensure your vehicle is in good condition and carry an emergency kit with essentials like a torch, first-aid supplies, food, and water.
