Temperature: Surface temperature predictions over land and sea. Temperatures less than -20°C are shown as white.
Rainfall: Precipitation rate in mm/h averaged over 3 or 6 hours. Blue shades show light rain while yellow and red show heavy rain. Precipitation can be rain, hail or snow.
Wind: Wind strength in knots (nautical miles per hour) is indicated by the coloured areas. The colours correspond to Beaufort forces (Gale Force, or Beaufort Force 8, is equivalent to 34 knots). Wind direction and strength are indicated by the arrows.
