Chaba, 20W, and the late Megi are two brand new storms (and one old one) that just formed right by the Phillipnes (excuse my spelling). It seems like this will be a battle of the storms, as the stronger of the two storms will surive while the weaker one will die because Chaba (the stronger one) will cause dry air to get into his ciruclation, from it's outflow. This is all happening while Megi caused epic floods in parts of South Korea.

I think both can survive - there's almost 25 degrees of longitude separating the two storms. They are both moving at about the same rate, just under 10 knots, and while there seems to be a "channel" between the two storms, I don't think it's anything that will cause the depression or Chaba to weaken. Usually the storm out ahead of the other storm wins out in the case of two very close storms; but, given sufficient distance between the two, the only impacts you might see are some upwelling of the waters ahead of Chaba in 2-3 days that limit intensification.

I've heard about a type of force that happens when two hurricanes become close enough that they form a common center point and spin around that point instead of the eye. Kind of like the planets orbiting the sun. Have you ever heard about this?

It's called the Fujiwara Effect. The Fujiwara Effect is the tendency for two nearby tropical cyclones to rotate around each other, so what you actually have happening is you have got one storm that would be the dominant storm, and they would rotate around each other, and it happened in the Pacific in the year 2001, and it happened in 1995 in the Atlantic, with Hurricanes Iris, Omberto and Karen all interacting at one point or another with each other. It's possible the two storms in the WestPAC will get some kind of Fujiwara effect in the next few days, if the is correct in their predictions.
