They are not on the same track except by a few hundred miles, the fact that the larger storm is following close to leading one argues against them combining forces, rather they will begin to compete for the favorable conditions with the stronger (lower-pressure) center winning out.
The most important thing is the water temp below the storms and the wind shear at the tops of the thunderheads; these are determined by upper air circulation and current variables.
Beyond filling the tank and laying in some grub, I wouldn’t rush around just yet.
