Thiruvananthapuram: The heavy rains lashing Kerala for the last two days is expected to subside by Thursday. But, there is a distant possibility of a depression forming in the Bay of Bengal in the first week of August.
The India Meteorological Department (IMD) hinted that Kerala would receive above average rainfall between August 2 and 20.
The two floods in Kerala were caused by heavy rainfall received from August 8 onwards. In 2018 and 2019, Kerala did not receive much rain in June and July. However, heavy and unabated rains lashed the state in August resulting in floods. A similar situation cannot be ruled out this year.
Last week, the IMD had warned that a depression could form in the Andhra Pradesh-Odisha coast between July 31 and August 6. It is unclear at the moment if this prediction will become a reality. But, Kerala is likely to get more rainfall during that period. If the said depression brings heavy rains to Kerala, flood could be a possibility.
Accurate prediction impossibleChanges in the nature of monsoon caused by global warming has made accurate prediction of rains impossible, said Dr. Venu G. Nair, a weather expert at the Centre for Research and Environment Management.
Rains that caused floods in Kerala the previous years happened on August 8-9 and 14-16 in the year 2018 and on August 8-9 in 2019.
K. Santhosh, director of Kerala Meteorological Department, said that more rainfall is expected in the coming days. Although severe rainfall has not been predicted, its possibility cannot be dismissed, he added.
