TAF - BECMG
How long can the becoming period be?
Looking at the doha TAF today I saw this:
TAF OTBD 202259Z 2100/2206 33006KT 9999 FEW025 BKN100 PROB30 TEMPO
2101/2110 VRB25KT 3000 TSRA FEW030CB SCT040 OVC100 BECMG 2112/2123 29005KT CAVOK=
between 12 and 23z it will be CAVOK. 11hours, can you really put a BECMG for 11hours?
