Forecast: Cold fronts to bring scattered showers along with huge surf

HONOLULU, Hawaii (HawaiiNewsNow) - A weak front will stall out and dissipate across the central islands today, with an increase in showers expected near the front. A second front is expected to approach from the northwest Thursday night and Friday, then stall just northwest of Kauai Friday night and Saturday. A third and stronger front is forecast to move through the area Sunday into early next week, potentially bringing some heavy rainfall to portions of the island chain.

The current northwest swell (300-320 direction) will subside this evening as a new northwest swell (320-340 direction) builds into the region. This new northwest swell will peak above High Surf Warning levels. An extra large northwest swell (310-330 direction) will arrive by Friday evening, quickly building to 20 ft 20 sec by Saturday morning. The northwest swell event this weekend has the potential to produce the largest surf of the season along exposed north and west facing shores.

A combination of large surf this week coinciding with peak monthly high tides may worsen beach erosion along shorelines exposed to north and west swells during the early morning hours.
