THIRUVANANTHAPURAM: Monsoon-like weather prevailed over Thiruvananthapuram, the gateway of the southwest monsoon into the Indian subcontinent, on Monday, with the city and its neighbouring areas receiving a steady drizzle punctuated by pattering bouts of rainfall since noon.
The whole of the State too received rainfall during the day, heavy in some places. A low pressure system was in position over the Lakshadweep Islands drawing rain clouds to the region.
The winds have still not started flowing from the west or southwest into the State's coast for the initial establishment of the monsoon current over the subcontinent. The northern limit of this streamlined seasonal flow from the Indian Ocean had been passing through a point around 500 km south of the southern end of the State since Friday.
With Kerala receiving widespread rainfall over the last couple of days and conditions favouring the same weather to continue into the week, scientists at the India Meteorology Department (IMD) were meeting in New Delhi on Monday to review their earlier forecast of the likely date of monsoon onset over Kerala. They had earlier forecast the onset to take place on May 30, with a margin of variation of four days either way.
The onset conditions can now be ignited by two weather systems now active over the seas off the subcontinent. The first is the mild low pressure system that has fallen into place over the Lakshadweep Islands, which is the cause for the present widespread rainfall.
The second is another low pressure system, the remnant of the erstwhile severe cyclonic storm Laila, which was hovering over northwest and adjoining west central Bay of Bengal far away from Kerala on Monday. Taliparamba, Kozhikode, Piravam, Mavelikara, Mancompu, Chengannur, Kumarakom, Kollam and Thiruvanthapuram airport received 3 cm of rainfall each during the 24 hours ending 8.30 a.m. on Monday. The State is likely to receive isolated heavy rainfall during the next two days, director of Thiruvananthapuram Meteorology Centre K. Santhosh said.
