Parts of Kerala are likely to experience widespread heavy rainfall, especially in southern Kerala, over the next few days as atmospheric conditions change. The strengthening of pre-monsoon-like conditions is expected to trigger widespread rainfall across the State, although intense spells of rain are likely only in the second half of the month.

According to a weather bulletin issued by the India Meteorological Department (IMD) on Thursday (May 7, 2026), an upper air cyclonic circulation formed over the southeast Arabian Sea and adjoining Lakshadweep off the south Kerala coast, extending up to 1.5 km above mean sea level. In addition, a trough/wind discontinuity now runs from this cyclonic circulation to southwest Madhya Pradesh across interior Karnataka and Maharashtra at 0.9 km above mean sea level.

The system is expected to power isolated heavy rainfall in southern Kerala in the coming days. A yellow alert has been issued for Thiruvananthapuram, Kollam, Pathanamthitta, and Kannur on Friday (May 8, 2026), warning of rains in the range of 64.5 mm to 115.5 mm in 24 hours. As many as nine districts in southern and central Kerala are put on yellow alert on Saturday (May 9, 2026) and seven districts on Sunday (May 10, 2026).

Meanwhile, parts of Kerala also started to record heavy rainfall. Koyilandy in Kozhikode recorded the highest rainfall of 100 mm during the last 24 hours ending at 8.30 a.m. on Thursday, followed by Thattathumala in Thiruvananthapuram with 80 mm, Vellanikkara in Thrissur, Taliparamba in Kannur, and the Malampuzha dam area in Palakkad with 70 mm each.
