In windy conditions, what is a key consideration for placing a handline?

Explanation:
In windy conditions, the key is to anticipate how the fire will move and place the handline to intercept the forward spread while accounting for possible wind shifts. Wind alters both the direction and speed of the fire, so building the line ahead of where the fire is heading helps keep it from crossing the line. By planning for wind shifts, you choose tie-ins and anchors that will still be effective if the wind changes direction or strength, reducing the chances of gaps, embers crossing the line, or the head of the fire outrunning the line. This approach keeps the operation safer and more controllable. Other ideas fall short because they ignore how wind shapes fire behavior. Ignoring wind can lead to a line that the fire reaches quickly. Always placing uphill regardless of fire direction can misalign the line with the actual spread path. Using wind alone to determine line length oversimplifies the situation, since terrain, fuels, existing fire behavior, and safety must also be considered.
