@zaff1262@MasRainman As mentioned in my earlier outlook, the first fortnight of June looks active with good monsoon rainfall across the southern states. A brief break may follow later. Overall, Southern India is likely to see near-normal rainfall, while the rest of India may end with a deficit.

π§οΈ Southwest Monsoon has officially set in over Kerala today (04 June 2026).
The Northern Limit of Monsoon (NLM) has made further progress, advancing into more parts of the Arabian Sea, Coastal Karnataka, a small part of South Interior Karnataka, parts of South Tamil Nadu, and additional areas of the Bay of Bengal.
The steady northward advance of the NLM reflects strengthening monsoon flow, enhanced moisture transport, and favorable large-scale conditions across the region.
Further advancement is likely during the coming days.
