Record rainfall, damaging winds and huge surf all happening Tuesday

PORTLAND, Ore. (KOIN) — The giant fire hose of the Pacific Ocean, aka the Atmospheric River, aimed at us Tuesday is considered strong which means it is beneficial, yes, but also mostly hazardous. Too much of a good thing.

A strong low pressure system that’s teaming up with this atmospheric river will deliver more than inches of rain. This storm will bring down trees, cause power outages, areas of flooding, huge surf and some storm surge during high tide along the south Washington coast.

In Portland, 24-hour rain totals of 1.5" to 2" inches are expected. There will also be strong wind, with southerly wind gusts reaching up to 45-55 mph for the valley.

Meanwhile, snow levels rest well above mountain passes Tuesday morning. Colder temperatures arrive late at night which should bring snow to mountain passes late Tuesday night into Wednesday and Thursday.  

Stay high and dry

The combination of extremely large waves, very high tides, a 2.5 to 3.0 ft surge/tidal anomaly and high river flows has the prompted the issuance of a Coastal  Flood  Warning for the south Washington coast. The forecast high tide Tuesday afternoon for Toke Point is  9.6 ft. Up to a 3.0 surge/anomaly is expected, producing a total tide closer to 12 ft.
