So, the actual 18Z position of 14.8N, 49.1W, compares to these two points in the 12Z UKMET, which are for both 6 hours earlier and 6 hours later:
1200UTC 30.08.2022 0 14.8N 48.3W 1009 25
0000UTC 31.08.2022 12 15.6N 49.4W 1009 24
Using interpolation, the actual 18Z position is 0.4 S and 0.25 W of the 12Z UKMET 18Z forecast point, which is ~45 miles SSW of the 12Z UKMET estimated position.
