NEW DELHI/ THIRUVANANTHAPURAM: The onset of southwest monsoon over Kerala has been delayed from the date forecast by the Met department due to its "sluggish" pace with 12 of the 14 districts in the state receiving scanty rainfall over the last 24 hours. Two districts Idukki and Pathanamthitta remained dry.
While Aluva and Kozha in Ernakulam and Kottayam districts respectively, received 6 cm rainfall each, in the rest of the centres it was 3 cm or less. The local met office has predicted rain or thunder showers at many places in Kerala and Lakshadweep over the next four days.
The normal date for onset of monsoon over Kerela is June 1. It also marks the official onset on rains in the country. This year, the Indian Meteorological Department
(IMD) had predicted that it will hit the southern state on May 30.
According to Skymet, a private forecasting agency, monsoon arrived over Andaman and Nicobar Islands on May 16, three days prior to the onset date. Since then, the advance has been slow.
By May 21, the southwest monsoon advanced over Bay of Bengal touching southern parts of Sri Lanka. But here on, the monsoon stagnated for a week. “The Arabian Sea branch of the southwest monsoon made very slow advance and is yet to reach the extreme southern tip (Kerala) of India. Cloud build up on either side of the sea was looking promising till a few days back for the timely onset over Kerala. However, it slowed down as the cloud pattern became a little diffused and unorganised," Skymet said. However, the IMD has refused to call it a delay, but said that the progress was sluggish.
"As per our forecast, there is +/- difference of four days, which is from May 27 to June 3. "At this moment,monsoon has already entered the Arabian Sea, crossed Sri Lanka and entered the Bay of Bengal. We are closely monitoring its progress. During the progress of monsoon, it is often observed that its pace varies," said Krishnanand Hosalikar, Deputy Director, IMD. But pre-monsoon rain is still being observed in Karnataka and Kerala. "In the last 24 hours, Karnataka has observed good rainfall. Kerala too experienced good rains on May 28 with Pampakuda in Ernakulam district recording 55mm of rains. Udayanampuram in Kottayam district received 37mm of rains while Mundathicode in Thrissur observed 30mm of rainfall.
On May 29, the rainfall activity in Kerala became minimal with isolated places receiving very light rain. "However, in the last 24 hours, some rainfall has been observed in the state but the weather activity has been patchy in nature, which is not the characteristic of monsoon," Skymet added.
