Decision
Based on the data through 04 UTC, is there any reason to amend the 00 UTC TAF? If not, click No Change Required below. If a section needs to be amended, choose it from the list below.
The correct answer is B.
The first change group (1) needs to be amended because patches of fog have formed at the airport and dropped the visibility to 1000 m. The second change group indicates that the stratus should disperse in the morning after sunrise. Since that's what we expected, it needs no amendment. The third change group does not need to be amended and, in any case, it will be updated in the next TAF.
