Lightning and Thunderstorm Safety Advisory

Authorities have also highlighted the dangers associated with lightning, which can cause serious injuries, fatalities, and damage to electrical appliances.

People are advised to avoid open spaces, rooftops, and outdoor activities, especially between 2 PM and 10 PM when skies remain cloudy. At the first sign of lightning or thunder, individuals should move indoors and avoid contact with electrical devices, metal objects, doors, and windows.

Swimming, bathing, flying kites, standing under trees, and staying near water bodies during thunderstorms should be avoided. Those travelling in vehicles should remain inside with minimal contact with metal surfaces.

Emergency officials have stressed that lightning victims do not retain electric charge, meaning immediate first aid can be safely provided. Quick medical attention within the first few moments after a lightning strike can significantly improve survival chances.
