# Commission Implementing Regulation (EU) 2017/373 of 1 March 2017 laying down common requirements for providers of air traffic management/air navigation services and other air traffic management network functions and their oversight, repealing Regulation (EC) No 482/2008, Implementing Regulations (EU) No 1034/2011, (EU) No 1035/2011 and (EU) 2016/1377 and amending Regulation (EU) No 677/2011 (Text with EEA relevance), Appendix 1

Extent: E+W+S+N.I.

To be included if visibility or runway visual range < 1 500 m; for up to a maximum of four runways.
Heavy used to indicate tornado or waterspout; moderate (no qualifier) to indicate funnel cloud not reaching the ground.
Template for METAR
Key:
Minclusion mandatory, part of every message;
Cinclusion conditional, dependent on meteorological conditions or method of observation;
Oinclusion optional.
Note 1: The ranges and resolutions for the numerical elements included in METAR are shown below this template.
Note 2: The explanations for the abbreviations can be found in Procedures for Air Navigation Services — ICAO Abbreviations and Codes (PANS-ABC, Doc 8400).
