  Let $v_1,\ldots,v_m$ be points in $\mathbb{R}^n$, and let $w_1,\ldots,w_m$ be
positive real weights. The weighted Fermat-Weber points are those points $z$
which minimize $\sum w_i d(v_i, z)$. Following Com\u{a}neci and Joswig, we
study the weighted Fermat-Weber points with respect to an asymmetric tropical
metric. In the unweighted case (when $w_1 = \cdots = w_m = 1$), Com\u{a}neci
and Joswig showed that the set of Fermat-Weber points is the "central" cell of
the tropical convex hull of $v_1,\ldots,v_m$. We show that for any fixed data
points $v_1, \ldots, v_m$, as the weights $w_i$ vary, the set of all
Fermat-Weber points is the entire tropical convex hull of the $v_i$.
