Tropical Storm Lane is about 1850 miles east southeast of Hilo Hawaii. This storm has maximum sustained winds of 70 mph and is moving west at 14 mph. Lane will continue to move over warm water and these conditions will support further intensification and Lane is expected to become a hurricane tonight and should become a major hurricane later tomorrow or tomorrow night. The growing tropical cyclone will remain on a mostly westerly course the rest of today and tonight then move on a more west northwest course tomorrow through the upcoming weekend. Lane is expected to pass just south of the Big Island of Hawaii during Tuesday night and Wednesday of next week. This could produce rough surf and rip currents along south and east facing beaches of the Big Island northward to the island of Maui.

There are no other areas of concern for development across the East Pacific basin.

For Friday morning that swell looks to dish up head high to OH sets at the most exposed South facing breaks. To reiterate… the swell is pretty steep and will be discriminating about what beaches it visits. 180-185 degrees, so think The OC, San O’ areas and all other South facing breaks will see some surf to a lesser degree.

ABOUT THE SWELLMAGNET FORECAST – One of the most exciting–and yet most challenging–aspects of surfing is the sheer variety of waves and weather conditions that affect the entire surfing experience.
