Early August brought severe advisories for the central highlands, with downpours exceeding 100 mm in Kandy and Nuwara Eliya. On 4 August, an intensifying southwest monsoon brought gusts up to 70 km/h and rough seas from Chilaw to Hambantota, prompting warnings for residents in low-lying areas and instructions for fishermen to stay ashore. By 10 August, reports indicated widespread showers and thundershowers, particularly in Sabaragamuwa and the districts of Kandy, Nuwara-Eliya, Galle, and Matara. Afternoon thundershowers were anticipated in Uva and eastern provinces, including Mullaitivu.
