This year Kerala has not witnessed generous monsoon rain. The onset of monsoon was also weak. On few occasions in June and July, Kerala has witnessed vigorous monsoon condition but it did not last for long. Since last one week or so, subdued Monsoon conditions are going on over Kerala and adjoining parts of South Peninsula.
Until now, Kerala remained rain deficient, barring few days of August when it was in a normal rain category. Despite being in a normal range category monsoon rain was in minus. Now once again, Kerala has become rain deficient.
We do not expect much weather activity over the state for at least the next 48 hours. Rains may increase to some extent by August 22nd or 23rd. There may be a light to moderate rain with few heavy spells over Kerala between August 24 and 27. These rain activities will maintain the daily average, but Kerala may not become rain surplus throughout the monsoon season now.
Average rainfall for Kerala is highest among the southern States. Therefore, to maintain the status quo, Kerala needs moderate to heavy rainfall to continue for days together. But this scenario does not seem to be possible during rest of the monsoon period.
