You might have heard forecasters talking about this, or you may hear about it soon. The reason I have brought this up is there is a slight possibilitythe remnants of a tropical system could impact Kentucky next week. 

 

The Fujiwhara Effect is a meteorological phenomenon where two nearby cyclonic (rotating) weather systems, like hurricanes or tropical storms, move around each other in an "intense dance." They orbit a common center, which can result in one storm absorbing the other, the storms merging into one larger system, or them eventually separating and moving on their own paths.

Rotation: The two storms spin in the same direction and begin to circle each other. 
Proximity: The effect occurs when storms are close enough to each other, typically within 850 miles (1,400 km). 
Outcomes:
Absorption: The stronger storm can absorb the weaker one, leading to a single, larger system. 
Merging: The two systems can combine to form one larger storm. 
Separation: The storms can continue to orbit for a period and then separate, taking different paths. 
Disruption: The interaction can also disrupt the storms' structures, potentially weakening one or both systems due to wind shear. 

 

What it means for forecasting:
The Fujiwhara Effect makes storm forecasting highly complex and uncertain. 
Meteorologists watch for this phenomenon, as it can drastically change the predicted path and strength of storms. 
Coastal residents should remain aware and prepared for potential sudden changes in storm forecasts and impacts, such as flooding or high winds.

Very interesting and reminds me some of binary star systems and black holes merging.  Please keep us posted.
