1. <strong>Weather</strong> groups are constructed by considering columns 1 to 5 above in sequence, i.e.,<br />
intensity, followed by description, followed by weather phenomena (e.g., heavy rain<br />
shower(s) is coded as +SHRA).<br />
2. No symbol denotes moderate intensity. No intensity is assigned to Hail (GR) or Icing<br />
(IC).<br />
3. Tornadoes and waterspouts in contact with the surface are coded +FC.<br />

Figure 6-10 — Sky Condition in METAR<br />
The sky condition group (Figure 6-10) gives a description of the appearance of the sky including<br />
the type of clouds, cloud layers, amount of sky coverage, height of their bases, and any obscuring<br />
phenomena. Cloud layer amounts for each layer indicate eighths of the sky that is covered,<br />
according to the abbreviations in Table 6-3, which is the same as Table 5-3.<br />
