The models(Below) are for TS Kristy soon to be Hurricane Kristy.
The NOGAPS MODEL puts Kristy in a path where we could see a Fujiwara effect.

What is a Fujiwara effect? For those who wanna know...

"When the cyclones approach each other, their centers will begin orbiting cyclonically about a point between the two systems. The two vortices will be attracted to each other, and eventually spiral into the center point and merge. When the two vortices are of unequal size, the larger vortex will tend to dominate the interaction, and the smaller vortex will orbit around it.

The effect is often mentioned in relation to the motion of tropical cyclones, although the final merging of the two storms is uncommon. The effect becomes pronounced in these storms when they approach within about 1450 km (900 miles) of each other and are at tropical storm strength or stronger."
