What does "DSNT" signify regarding the distance of weather phenomena from the observation point?

"DSNT" signifies that weather phenomena are occurring beyond a specified distance from the observation point, which is typically understood to mean beyond 10 statute miles. This term is used in weather reporting to indicate that while significant weather is present, it is not within close proximity to the observer or station.

In the context of aviation weather observation, clarity about distances is crucial for flight safety. The designation "DSNT" helps pilots and meteorologists ascertain whether weather conditions, such as thunderstorms or heavy precipitation, might impact their operations or if they can expect clearer conditions nearby.

The other options present different distances that might misrepresent the definition of "DSNT." It's essential for weather reports to use standardized terminologies, and "DSNT" specifically reflects the distance threshold of beyond 10 statute miles for accurate communication of weather conditions.
