This year, Southwest Monsoon made a delayed start by almost a week. Even after the onset of the Monsoon, it continues to be slow and weak. Southwest Monsoon is yet to advance in the interior parts. As of now, rains have been confined to Coastal parts of Kerala, Karnataka, and Bay of Bengal region. The sluggish and weak Monsoon is reflecting on pan India and at present India is deficit by 46% in this Monsoon season.
Kerala and Coastal Karnataka are the rainiest pockets during the Monsoon season. At the time of the onset of Monsoon, there is a change in the air mass. This time, rainfall has been confined to the West Coast solely, rains have underperformed over the coastal areas.
There has not been a single day when the rainfall has exceeded the normal in Kerala and Karnataka. From June 1 to June 7, Coastal Karnataka and Kerala have been a rainfall deficit by 76% and 60%, respectively.
In the past few days, there have been good rains, but they have been below normal in Kerala. Thus, the deficiency has been further pulled down and stands at 36%. Whereas, the deficiency levels in Karnataka has risen to 81%.
Weather Outlook:
Moderate rain and thundershowers would continue in both the pockets of Coastal Karnataka and Kerala. The routine range of rains over these places will be between 20mm-40 mm which is not heavy for these pockets.
Cyclone Vayu is still there in the Arabian Sea, with the help of south westerlies conditions are likely that moderate rains would be affecting parts of Kerala and Karnataka for the next few days. However, this will not be suffice to pull down the deficiency levels.
In order to witness good spell of rains, a fresh surge is needed once the impact of Cyclone Vayu fades away.
