The location of occasional lightning cloud to cloud and in the cloud observed to the distant west is reported as?

The correct answer relates specifically to the type and location of lightning being observed. In aviation weather reporting, the convention involves abbreviations that convey critical information succinctly.

The term "OCNL" stands for "occasional," indicating that the lightning is not continuous but happens at intervals. The notation "LTG" signifies "lightning," which is further specified by the descriptors following it. The part "CC" denotes "cloud to cloud" lightning, while "IC" indicates "intra-cloud" lightning. The use of "DSNT" indicates that the source of this observable lightning is distant, and "W" points to the direction the lightning is observed from, which in this case is west.

Therefore, the full reporting in the correct option provides a complete understanding that there is occasional cloud-to-cloud and intra-cloud lightning detected at a distance to the west. This excellently conveys the type and location of the lightning activity to those interpreting weather data for aviation safety.

This detail is crucial for pilots and air traffic control to assess weather conditions and make informed decisions regarding flight safety.
