Overview

• Heavy rain triggered significant flooding in Newcastle, Co Down, with some residents unable to leave their homes and roads turning into fast‑flowing streams.
• Shortly before midday, the Met Office extended its yellow rain warning to 3pm and widened it to Antrim, Armagh, Derry, Down and Tyrone, excluding Fermanagh.
• Locals described the downpours as the worst in decades, with sandbags used to protect properties as water and debris flowed off the Mourne Mountains.
• Forecasts cited totals of 20–30 mm widely and 60–100 mm over the Mournes, with an additional 10–20 mm possible before conditions eased.
• In the Republic, Met Éireann maintained Status Yellow warnings for several counties early Sunday and warned of localised and river flooding risk on higher ground, while earlier Orange alerts for Cork and Waterford had expired.
