HONOLULU (HawaiiNewsNow) -

A massive and dangerous northwest swell approaching the islands will bring surf of up to 40 feet by the end of the week, forecasters say.

The National Weather Service said surf will eventually build to warning levels by Thursday night and will peak on Friday.

For now, a High Surf Advisory is in effect for north- and west-facing shores of Niihau, Kauai, Oahu and Molokai and for north-facing shores of Maui. This is in effect until 6 a.m. Friday.

NWS said surf will rise to 10 to 15 feet along north shores on Thursday, while surf will build to 8 to 12 feet along west shores.

Forecasters warn the public to expect strong breaking waves, shore break and strong longshore and rip currents that will make swimming difficult and dangerous.
