They can interact and actually do a loop or circle around each other and sometimes can actually combine.

It's kind of aimed at the Big Island right now and the wind is pushing a lot of water in that direction. But it really is very early and there's certainly a possibility the direction could change.

Overall, our hurricane season has been very quiet this year. We've had one weak tropical disturbance so far, at the beginning of August, that lasted a day or two.

These systems make the air to the east and southeast of the low unstable, creating a greater chance of heavy rain showers.

All of a sudden, it's become quite an active period.

That's significant because when it crosses the 140-degree mark, it will be the first hurricane since late August 2003 in the Central Pacific.

It's something we have to track and be very aware of because based on the tracks right now they could affect the Hawaiian Islands toward the end of next week.
