Sea-level pressure maps — GFS

Sea-level pressure out to five days, to follow lows and highs.

This GFS map shows sea-level pressure every 3 hours out to five days. A low is an area of lower pressure than its surroundings; it often brings rising air, clouds, livelier wind and sometimes rain. A high has higher pressure than its surroundings and usually brings settled weather and clear skies. The map updates with each new model run; the run time and last update are shown under it. GFS is the American global model.
