Things are starting to get rolling in the North Pacific. High-pressure had been doing a decent job globbing up the storm track for the last several days but now, thanks to an infusion of warm tropical moisture jumping latitudes over by Japan, it looks like the high is going to move out of the way enough to let a couple decent sized storms move into our swell window.
At this point it looks like a strong WNW swell will move into Northern and Central California on the 12th and peak in those areas on the 13-14th. Wave heights will likely be double-overhead+, maybe bigger.
Southern California would see the beginning of that swell showing late on the 13th and likely peak on the 15th. Wave heights south of Point Conception will be quite a bit smaller…more in the waist-head high range for areas exposed to the NW and probably some bigger sets at the standouts.
This storm is about 4-5 days from forming so keep checking back for updates as we get closer.
