The National Weather Service of Portland has issued a high surf advisory in effect from 6 p.m. this evening to 9 a.m. Wednesday for the Northern and Central Oregon Coast.
A strong cold front is approaching the Pacific Northwest and will move onshore around sunset today. This system is generating seas upwards of 30 feet in the open Pacific which will be heading toward the Oregon Coast over the next several hours. By the time the swell reaches the coast this evening it will decay to around 20 to 22 feet, but this will still be enough to produce dangerous conditions in the surf zone.
Strong westerly winds behind the front will continue to drive large surf into the coast overnight tonight. Seas will gradually subside and the waves will become less energetic Wednesday morning.
It can be very dangerous to venture near the coast under high surf conditions. There have been several cases in the past where people have been swept off rocks and jetties and drown while observing high surf. Stay well back from the water's edge and be alert for the exceptionally high wave.
A high surf advisory means that high surf will affect beaches in the advisory area, producing rip currents and localized beach erosion.
