The Department of Meteorology has warned that if El Niño conditions develop during the southwest monsoon season, Sri Lanka could face a prolonged drought lasting until September.

Speaking at a media briefing held today (09), Additional Director General of Meteorology Ajith Wijemanna stressed the need for strict water management across all sectors, including drinking water and irrigation, under such circumstances.

He noted that the prevailing hot weather is expected to continue throughout April, with some relief anticipated after the southwest monsoon begins around May 20. 

However, he cautioned that significant easing of the current heat may only occur by the third week of May.

Wijemanna further explained that if El Niño persists during the southwest monsoon, rainfall in June, July, and August could be reduced, extending dry conditions until September.

He urged authorities and the public to pay special attention to water conservation and management in the coming months. (Newswire)
