Warm Front Bands are associated with multi-layered cloudiness, with clearances in the warm sector. Precipitation can be
found well ahead of the surface front until just after front passage.

Description
|
Precipitation
|
- Rainbands typically 50 kilometres wide and a few hundred kilometres long, usually orientated at a small angle to the
surface front
- Slight, moderate or heavy precipitation ahead of the surface front
- In winter, snow ahead of surface front, freezing rain (drizzle) is possible.
- After the front passage small areas of drizzle (light snow in winter)
|
Temperature
|
- Rises after the passage of the front
|
Wind (incl. gusts)
|
- Veering of the wind at the front passage
- Sometimes in warm sector increasing and more gusty winds
|
Other relevant information
|
- Precipitation areas move faster than surface front (embedded in Warm Conveyor Belt).
- Sometimes moderate to severe icing ahead of surface front
- In wintertime, in the warm sector high risk of fog
- In warm sector, low level turbulence possible
- In summer, thunder possible, most likely at the warm side of the front
- Apart from fog in winter and spring, the warm sector is a dry area with clear patches.
