LONDON (AP) — Snow is causing travel disruptions across central England and northern Wales, grounding flights, shutting down roads and causing traffic accidents. Birmingham and London Stansted Airports suspended flights as runways were cleared. The airports both advised passengers to contact their airlines to check their flight status. "Please be advised that flight delays and cancellations are expected due to the adverse weather conditions," Stansted warned. The M1 motorway — the main highway between London and northeast England — was partially closed in Leicestershire. Police in Wales warned against all but the most essential travel amid persistent snowfall that is forecast to last throughout the day.
