The India Meteorological Department’s October 4 district warnings identify six Kerala districts for isolated heavy rain on Monday, October 5: Pathanamthitta, Idukki, Malappuram, Wayanad, Kannur and Kasaragod. The official records mark these districts in yellow and list heavy rain alongside thunderstorms, lightning and strong surface winds.
Times Kerala’s October 4 report independently carries the same six-district list. Kerala’s October 4–6 wet spell was already forecast in the October 2 bulletin previously reported by Asal Sach. The latest district details provide a more current guide to where heavy rain is possible; they do not establish that heavy rain or flooding has occurred in all six districts.
For Tuesday, October 6, IMD’s district records identify Idukki, Ernakulam, Thrissur, Palakkad, Malappuram and Wayanad for heavy rain. The change in the list matters: a district’s warning for Monday cannot simply be carried over to Tuesday. Yellow shading can also represent other hazards, so a thunderstorm warning elsewhere should not be described as a heavy-rain alert.
The national bulletin issued at 12:50 p.m. IST on October 4 forecasts isolated heavy rain through October 6 in Kerala and Mahe, coastal Karnataka, and Tamil Nadu, Puducherry and Karaikal. For south-interior Karnataka, its detailed forecast specifies October 5 and 6. These are localised heavy-rain risks within the named regions, not a prediction of uniformly heavy rain across entire states.
DT Next, reporting the Chennai Regional Meteorological Centre’s Sunday forecast, identifies the Nilgiris, Coimbatore, Theni, Krishnagiri and Dharmapuri, along with ghat areas, for heavy rain on Monday and Tuesday. The official district records also list heavy rain for those five districts on both days. Chennai’s forecast is different: DT Next reports light to moderate showers with thunder and lightning on Monday evening and night.
IMD links the southern weather to an upper-air circulation over the Gulf of Mannar and adjoining southern coastal Tamil Nadu, with a trough extending towards the east-central Arabian Sea. Its national advisory asks farmers in the affected southern regions to maintain field drainage and support vulnerable crops. Residents should consult updated district warnings and short-term local advisories before travel or outdoor work; this forecast does not establish a damage toll or a closure order.
