What is the implication of a TEMPO condition forecasting less than required visibility at your destination?

When a TEMPO condition forecasts less than the required visibility at your destination, it indicates that the weather may deteriorate briefly, which can affect your ability to safely land at that airport. In aviation, visibility is crucial for safe approaches and landings, and if the forecast suggests that visibility may drop below the required minimums, the implication is that an alternate airport may be necessary.

This is in line with regulations and best practices that ensure safety by allowing pilots to divert to an alternate if weather conditions at the destination are not conducive to a safe landing. Having an alternate available can help in case the visibility conditions do not improve, thereby ensuring that the flight can still be safely concluded at an airport where the weather is suitable.

The other options do not address the safety implications tied to potential adverse conditions at the destination airport, and therefore are less relevant in the context of making a decision based on the forecasted visibility.
