Colombo, 06 September 2026 – Sri Lanka’s Natural Hazards Early Warning Centre, under the Department of Meteorology (DMC), has issued an Amber-colored Warm Weather Advisory valid for tomorrow, 07 September 2026. The advisory, released at 04:00 p.m. today, cautions residents in several parts of the island about an elevated “Heat Index” reaching ‘Caution Level’ during daytime hours.
Regions Under Advisory
The advisory specifically targets the North-Central and Eastern Provinces. In addition, residents in the districts of Jaffna, Kilinochchi, Mullaittivu, Vavuniya, Kurunegala, Monaragala, and Hambantota are urged to prepare for the anticipated warmer conditions.
Understanding the Heat Index
The Heat Index, a crucial meteorological indicator, represents the temperature that the human body actually feels when relative humidity is combined with the air temperature. This advisory highlights that the “felt temperature” in the specified areas is likely to increase to a level requiring vigilance. The Department of Meteorology calculates this index for the next day using global numerical weather prediction model data, factoring in atmospheric humidity and maximum temperature values. It’s important to note that this is not a forecast of the maximum atmospheric temperature but rather how intensely the heat will impact the human body.
The advisory has been prepared with the valuable cooperation and advice from the Ministry of Health and Indigenous Medical Services, underscoring the potential health implications of these conditions.
Essential Actions to Ensure Safety
To mitigate the risks associated with the heightened heat index, the DMC and health authorities recommend several proactive measures:
- At Job Sites: Workers are strongly advised to stay adequately hydrated by drinking plenty of water and to take frequent breaks in shaded areas whenever possible.
- Indoors: Special attention should be given to vulnerable individuals. Families and caregivers should regularly check on the elderly and those with existing medical conditions.
- In Vehicles: The advisory issues a firm warning: Never leave children unattended inside vehicles, even for short periods, as temperatures can rise rapidly to dangerous levels.
- Outdoors: Individuals are encouraged to limit strenuous outdoor activities during peak daytime hours. When venturing outside, seek shaded spots and maintain consistent hydration.
- Dress Code: Opt for lightweight, loose-fitting clothing in white or light colours, which reflect sunlight and help keep the body cooler.
For additional guidance and further information regarding heat preparedness and response, the public is encouraged to refer to advisories issued by the Disaster Preparedness & Response Division of the Ministry of Health. For any further clarifications, individuals may contact 011-7446491.
