Amber Weather Warning Issued for Severe Lightning and Heavy Rains Across Sri Lanka

November 10, Colombo (LNW): The Department of Meteorology has issued an amber early warning for severe lightning and heavy thundershowers across multiple provinces and districts in Sri Lanka, effective from 1pm today (10), until 1 am tomorrow (11).

According to the Natural Hazards Early Warning Centre, residents in the Western, Sabaragamuwa, Central, and Uva provinces, as well as the Galle and Matara districts, should brace for heavy downpours exceeding 100 mm in some areas during the evening or night.

The department has also cautioned that thundershowers could bring strong gusty winds ranging between 60 to 70 km/h to adjacent sea areas, leading to very rough conditions.

Expected Impacts and Risks

Authorities have warned of potential hazards tied to the severe weather, including:

• Public Safety: Risk of injury or death from lightning strikes for individuals in open spaces such as paddy fields, plantations, playgrounds, beaches, and boats.
• Property Damage: Uprooted trees and structural damage to non-engineered buildings, including tin and thatched roofs.
• Infrastructure and Travel: Localised flash floods, slope failures in vulnerable areas, power and communication outages, damage to electrical equipment, and disruptions across road, rail, and air transport.
• Maritime Hazards: Dangerous conditions for small fishing boats and craft.

Recommended Actions

The Department of Meteorology advises the public to take immediate precautionary measures:

• Suspend outdoor work—including farming, plantation labour, sports, and construction—as storms approach.
• Seek shelter in a substantial building or an enclosed, hard-topped vehicle; avoid sheltering under trees, open huts, tents, or bus halts.
• Stay away from open fields, hilltops, beaches, tanks, rivers, and other water bodies.
• Fishermen and small-boat operators must remain ashore or return to land immediately.
• Avoid bathing, using wired telephones, and handling electrical appliances during thunder.
• Exercise caution by avoiding tree-lined and flooded roadways, and heed local flood and landslide warnings.
