11am July 4th Advisory: Beryl weakened to Category 3 as it moved past the Caymans and on to Mexico 

As Matamoros Mexico has almost three times population of Brownsville Texas, why is only Brownsville labeled on the map? To me it would be reasonable to hyphenate the two, as in Dallas-Fort or Minneapolis-St Paul, and to cater to the US audience, have it Brownsville-Matamoros in spite of the convention of the bigger first.
