Parts of Kerala are likely to witness moderate to isolated heavy rainfall for the next few days, triggered by the low-pressure system over the Bay of Bengal. According to a weather bulletin issued by the India Meteorological Department (IMD), a low-pressure area has formed over the Strait of Malacca and the adjoining South Andaman Sea on November 22. The system is likely to intensify into a depression over southeast Bay of Bengal around November 24.
Thereafter, the system is expected to intensify further during the subsequent 48 hours while moving west-northwestwards. In addition, a cyclonic circulation persists over southeast Arabian Sea and another upper air cyclonic circulation lies over Comorin area and adjoining Indian equatorial ocean. Under the influence of the system, parts of Kerala are likely to experience thunderstorms for the next five days.
A yellow alert has been issued for Thiruvananthapuram, Kollam, Pathanamthitta, Alappuzha, Kottayam, Ernakulam and Idukki on Sunday, where isolated heavy rainfall is likely. Similarly, these seven districts were put on yellow alert on November 25 and 26. On Monday, Thiruvananthapuram, Kollam, Pathanamthitta, Alappuzha, Palakkad and Malappuram were placed on yellow alert.
Meanwhile, Thiruvananthapuram recorded the highest amount of rainfall during the last 24 hours ending at 8.30 a.m. on Saturday, with Neyyattinkara recording 78 mm of rainfall during the period, followed by Thiruvananthapuram city 50 mm, Thiruvananthapuram airport, Punalur in Kollam, Pirappancode and Chacka in Thiruvananthapuram with 40 mm each. The rainfall activity is likely to be more vigorous in parts of south and central Kerala until the system weakens.
The heavy rain in Thiruvananthapuram forced the authorities to raise the shutters of Peppara and Aruvikkara dams by 10 cm each due to the rising water level. The District Collector informed that those living in the vicinity of both the dams should be alert due to the rising water level.
