The Met Office has issued an extended weather alert for thunderstorms, with a yellow warning for Northern Ireland starting earlier than originally planned. This warning, in effect from 9.15am to 9pm, predicts potential flooding, lightning, and hail in the affected areas today. Up to 30mm of rain could fall within a two-hour period, causing concerns over possible floods and damage to properties and structures.

The Met Office also warns of disruptions to driving conditions due to spray, standing water, and hail, potentially leading to longer travel times. Additionally, the agency highlights the possibility of delays in train services, building damage from lightning strikes, and potential power outages.

Residents in flood-prone areas are advised to prepare a flood plan and emergency kit, including essentials like torches, batteries, and mobile phone chargers. The Met Office emphasizes the importance of being ready for power cuts, stating that preparation can significantly improve how individuals cope with such situations.

Regarding lightning safety, people are advised to seek shelter indoors upon hearing thunder, avoiding trees or elevated structures that may attract lightning strikes. If caught outside during a thunderstorm, finding a safe enclosed shelter, such as a car, is recommended to reduce the risk of lightning-related injuries.

Stay prepared and stay safe during severe weather conditions to minimize risks and ensure personal safety.
