Felix isn’t close enough to anything else to interact.
When tropical systems are close to each other, they do a “Fujiwhara” - they spin around each other counterclockwise. Neither system gets stronger because of it - the weaker one tends to get weakened further, and sometimes basically disappates as it’s destroyed by the larger one.
I was just wondering if severe weather would occur in the area between the two storms.
I've never heard of that term, thanks.
