Estimated head/tailwind and crosswind for each runway end from the current reported wind.
Use this section to quickly compare current wind alignment across available runways at I19. This is intended as a planning aid only and should not replace official performance calculations or pilot judgment.
Current wind is variable at 5 kt, gusting 11 kt — light and variable wind like this is generally not a factor for runway selection, and with no steady direction there is no head/tail or crosswind component to compute. Live numbers return automatically once a report includes a wind direction.
