Overview
- The Met Office has multiple yellow rain warnings in force across England and Wales today, with forecasts of 20–30 mm widely and up to 50 mm in places, and 60–80 mm possible on high ground.
- An amber warning for central and south Wales is in place for late Sunday into Monday, with windward hills forecast to see 60–80 mm and isolated 100–120 mm totals, raising a serious flood risk.
- UK impacts could include surface‑water flooding, longer road and rail journeys, a small chance of power cuts, and brief hill snow where the rain meets colder air in northern and northeastern England.
- Across the U.S., winter storm warnings and advisories cover large parts of the Plains, Midwest and Great Lakes as heavy snow of roughly 6–14 inches and gusts near 35 mph create hazardous travel.
- Air travel is already snarled in the U.S., with more than 1,400 delays and over 800 cancellations reported Saturday and Chicago O’Hare the hardest hit, where a multi‑hour ground delay was issued.
