Overview
- Met Office yellow warnings for snow and ice cover much of the UK from Monday afternoon into Tuesday morning, with travel disruption and icy surfaces cited.
- Environment Agency data shows dozens of active flood warnings and nearly 200 alerts across England, reflecting saturated ground after recent heavy rain.
- UK snowfall is expected to be highly elevation‑dependent Monday night, with 1–2 cm at low levels, 2–5 cm above roughly 150 m and 5–8 cm above 300 m, plus strong coastal winds in the northeast.
- Met Office meteorologists are monitoring a deeper midweek low that could bring heavy rain, gales and hill snow, though guidance still shows notable uncertainty on track and timing.
- In the U.S., the National Weather Service flags a potentially significant Great Lakes winter storm Tuesday night into Wednesday with heavy snow, mixed precipitation and strong winds, while Central and Southern California face President’s Day flood watches, wind advisories and 1–3 inches of coastal rain with heavy mountain snow above about 5,000 feet.
