Thiruvananthapuram: The India Meteorological Department (IMD) has announced that the Southwest Monsoon 2026 is likely to arrive over parts of the South Bay of Bengal, Andaman Sea, and the Andaman & Nicobar Islands by the end of this week. As the monsoon nears, Kerala is bracing for a spell of heavy rainfall starting from mid-May.
Heavy Rainfall Warning: May 14 to 16
According to the latest bulletin from the IMD, isolated heavy rain is expected across Kerala between May 14 and May 16, 2026. Authorities have advised residents in hilly and low-lying areas to remain vigilant as the intensity of the showers is likely to increase during this period.
Low-Pressure Area and Cyclonic Circulation
The weather office has identified two major atmospheric systems currently influencing the region’s weather pattern:
- Low-Pressure Area (LPA): A low-pressure system is currently persisting over the Southwest Bay of Bengal. It is expected to intensify further within the next 48 hours, potentially bringing more moisture and wind towards the southern peninsula.
- Cyclonic Circulation: An upper-air cyclonic circulation is situated over South Karnataka at an altitude of 5.8 km above sea level. This system is contributing to the unstable weather conditions and pre-monsoon activity in Kerala.
Thunderstorms and High-Speed Winds
Over the next five days, Kerala and Mahe are expected to experience isolated thunderstorms accompanied by lightning. The IMD has also warned of gusty winds reaching speeds of 30 to 50 km/h.
