Friday, Dec. 11th – Lincoln County
Summary: Yesterday’s cold front really stirred things up, beginning with a strong blast of wind in the morning; gusts to around 60 mph were common in our local communities. Then came heavy showers, accompanied at times by flashes of lightning and booming thunder. By midday, the thunderstorms began growing more intense, dropping pea-sized hail as they rolled through the Central Coast. An F1 tornado with winds up to 104 mph touched down southwest of Battle Ground, Washington, at 11:15am. The unstable showery atmosphere continued through the evening and through most of the night. At daybreak this morning, it was raining with south winds 15-25 mph.

A Coastal Flood Warning remains in effect for the Central Oregon Coast until 4:00pm this afternoon.
A Coastal Flood Advisory is in effect from 9:00am 3:00pm Saturday for the Central Oregon Coast.
* Tides and storm surge: high tide around 10 feet combined with a 1.5 to 2 foot storm surge around noon today. A similar high tide is expected around noon Saturday, but with a slightly smaller storm surge anticipated.
* Tidal overflow: areas not subject to direct wave action will experience overflow surge into estuaries and bays with water levels higher than normal tides would suggest.
* River flows: rivers will be running high due to runoff from the recent rainfall. A high runoff will increase flood potential in the tidally influenced reaches and estuaries of the coastal rivers.
* Waves and wave impacts: 25 to 35 foot breakers are expected for today. The waves will wash over the jetties, throw logs and debris far onshore, create large surges of water onto the beaches, and cause significant beach erosion.
* Flooding impacts: flooding of low-lying areas and roads prone to tidal flooding can be expected an hour or two before and after the high tides. The greatest impacts will be between 11:00am and 2:00pm.
* This is a dangerous situation. Residents and local officials should take immediate action to protect life and property in low-lying areas affected by these abnormally high tides and surf.
