This shows clouds, not rain. Clear sky doesn’t always mean dry, and some rain falls from low cloud that hardly shows. It isn’t a warning.
Satellite: Much wetter than usual in the last 3 days: Ratnapura, Kandy and Kegalle.
Next day: Kurunegala, Kandy and Anuradhapura could be much wetter than usual over the next day (weather model).
Details ›Each card comes from its own source. Only NBRI issues landslide warnings. How these cards work
NBRI’s advice, as issued:Since the rainfall within the past 24 hours has exceeded 100 mm, if the rains continue, be on alert on the possibility of landslides, slope failures, rock falls, cut failures and ground subsidence, being ready to evacuate to a safe location if the need arises.
