Clallam County

Smoke overhead

1. A smoke day is a date on which a smoke plume traced by NOAA Hazard Mapping System analysts from satellite imagery covered this place's point (the county's population centre or the city centre). Counts here are of medium or heavy smoke. Since 2018 analysts have often drawn light smoke as one area over most of the continent, so light-smoke counts are not comparable from year to year. The plumes show smoke anywhere in the air above, not air quality at the ground, and smoke hidden by cloud is missed.

River crests

River gauges

1. Crests are the highest and the recent crests the National Weather Service lists for each river gauge in the county that has a flood stage, not every flood. Flood categories use each gauge's current flood stages; crests from before levees, dams or channel changes may not be comparable. Crests measured on an old datum are left out of the rankings.

High tide flooding

Other tide gauges here: Port Angeles (record 12 days, 1982).

1. High tide flooding days are days on which a NOAA tide gauge recorded water at or above NOAA's minor flood threshold, set from the gauge's tide range, counted by meteorological year (May to April). These are the counts in NOAA's annual high tide flooding reports; they are not National Weather Service flood stages. Years with less than 80 percent of data are left out.

1. The Palmer Drought Severity Index is computed by NOAA each month from the county's average temperature and precipitation, relative to the county's own climate. Zero is normal; -3 or lower is severe drought and -4 or lower extreme drought. It describes the long-term balance of moisture, not water supply or crop losses.

Every earthquake of magnitude 4 or more within 50 miles

1. Earthquakes of magnitude 2.5 or more in the USGS Comprehensive Catalog since 1900. Within 50 miles means the epicentre lies within 50 miles of the county boundary (or inside the county).
2. Small earthquakes were under-recorded before the modern seismic networks of the 1970s and are still missed in remote areas, so early decades read low. Magnitudes are as the catalogue reports them and mix scales (moment, local and body-wave).

Tsunamis

1. Places where NOAA's Global Historical Tsunami Database records a tsunami's water arriving, with the greatest height it reached above sea level at the time. Only tsunamis NOAA rates probable or definite are counted. Heights from eyewitness accounts and tide gauges are mixed, and older events are less completely recorded.

Volcanoes within 100 miles

1. U.S. volcanoes within 100 miles, from the USGS Volcano Hazards Program. The threat category is the USGS 2018 National Volcanic Threat Assessment, which ranks volcanoes by how hazardous their past eruptions were and how many people and how much infrastructure lie near them. It is not a forecast of eruption.

Mapped landslides

Mapped by WA WGS (3,032), NASA (18), West Coast Slow Moving (Yuankun and others, 2021) (15).

Deadly landslides

1. Landslides mapped in the USGS compilation of landslide inventories across the United States (version 3.0, 2025), rated probable or better. The compilation joins inventories made by federal and state agencies for different purposes and areas, so the number mapped in a county reflects how closely it has been surveyed as much as how often its slopes fail. An area with few records may simply not have been mapped. Deaths are as recorded in the inventories; a slide listed in two inventories is counted once.

1. Nov 14, 2021Flood$5.5 million
   National Weather Service narrative

   Heavy rain and some snow melt caused flooding throughout much of Clallam County, especially on the Bogachiel and Elwha Rivers. Flooding reached major severity and preliminarily a record stage. Many road, highways, and bridges closed due to water over roadway, washouts, sloughing, and debris. There was urban and small stream flooding as well on the 14th - 15th. The heavy rain also triggered a number of landslides throughout the area. Damages are reported and estimated; not all damages have been identified. Crop damages are unknown.

2. Jan 7, 2009Heavy Rain$4.0 million
   National Weather Service narrative

   Heavy rain caused some flooding and landslides, which damaged several roads and about a dozen homes. Along with the heavy rain, faulty drainage accounted for some flooding in Sekiu. The waterfront trail in Port Angeles was closed due to fallen trees and small landslides. A bridge in western Clallam County was washed out, stranding a few families. There were numerous other county roads impassible from flooding.

3. Dec 3, 2007High Wind, Olympics$2.0 million
   National Weather Service narrative

   Roads were either washed out or covered by fallen trees.

4. Nov 15, 2006High Wind, Western Strait Of Juan De Fuca$1.0 million
   National Weather Service narrative

   Some buildings, homes and cars were damaged. The cars were damaged from wind borne debris. A spotter between Sekiu and Clallam Bay reported winds gusting into the 60s and 70s for most of the day (about 5 am - 3 pm).

5. Nov 26, 2006Heavy Snow, Eastern Strait Of Juan De Fuca$1.0 million
   National Weather Service narrative

   Four to 10 inches of snow fell. The heavy snow downed trees and power lines and caused travel problems.

6. Jan 12, 2021High Wind, Eastern Strait Of Juan De Fuca$700,000
   National Weather Service narrative

   After strong winds affected the area beginning during the late evening hours of 12th and through the early morning hours of the 13th, the USCG reported and responded to multiple vessels impacted by high winds around Anacortes, Washington. A pier sunk, and several boats were pulled loose from moorings, with one floating adrift.

7. Nov 28, 2021Flood$600,000
   National Weather Service narrative

   Heavy rain of 5 to 10 inches caused flooding on many rivers, including the Bogachiel, Nooksack, Samish, Skagit, Skokomish, Stillaguamish Rivers. There was urban and small stream flooding as well. The heavy rain also triggered landslides throughout the area. Significant flooding on the Nooksack River, for the second time this month, overflowed at the City of Everson to the degree that flood waters flowed north along an old Nooksack floodway and Johnson Creek where it flooded the cities of Everson and Nooksack, WA, then combined with flooding from the Sumas River and flooded the City of Sumas, WA. |Damages are reported and estimated; not all damages have been identified.

8. Jan 5, 2006Heavy Rain$600,000
   National Weather Service narrative

   The Governor declared a state of emergency after rain, at times heavy, over a period of about 10 days, caused over 7 million in damage, mainly to transportation infrastructure throughout western Washington. Mudslides closed parts of I-5 near the Pierce-Thurston county line, part of Highway 20 about a half mile east of Concrete, Highway 107 near Raymond, and Highway 166 near Port Orchard - where 3 cars crashed in the mud. In Bremerton, they totaled 16.2 inches of rainfall in 3 weeks, an amount which normally falls in 2 months. Mudslides halted Amtrak passenger train service between Everett and Olympia. In King County, there were 19 road closures from water over the roadway. Many…

Major flooding occurred on the Tolt, Snohomish, Skokomish, Skagit, and White rivers. Other rivers flooding were the Satsop, Cedar, Wynoochee, Elwha, Deschutes, Dungeness, Skookumchuck, and Chehalis.

10. Dec 4, 2003High Wind, Eastern Strait Of Juan De Fuca$500,000
    National Weather Service narrative

    Strong east winds blew over much of the eastern part of Puget sound, knocking out power to nearly 250,000 customers. High winds also shut down dozens of schools and fallen trees made many roads impassable. All schools were closed in Enumclaw, Issaquah, Monroe, and Snoqualmie, while some were closed in the Lake Washington, Bellevue and Riverview districts. In Maple Valley, a couple was injured when a tree fell on their moving vehicle. Over 500 homes were damaged, most from fallen trees.
