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.

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 USDA-FS AK Tongass (1,968), AK DOT (38), USGS AK Glacier Bay Slow Moving (30), USGS AK Glacier Bay (23), USGS Seismogenic Mass Movements (9), NASA (5).

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.

   National Weather Service narrative

   A stregthening low moved by Saint Paul Island, deepening to 970 mbs near the entrance of Kuskokwim Bay late Wednesday morning. The low then moved inland just east of Bethel Wednesday afternoon, beginning to weaken and turn east. By Friday morning, the low had weakened and moved to 60 miles south of Cape Yakataga, however strengthening high pressure from Bristol Bay into the central Alaskan interior kept strong north winds going in and near Prince William Sound. Wind gusts on Tuesday reached 54 mph at Cape Romanzof. On Wednesday, gusts reached 64 mph at Cold bay, 60 mph at Port Heiden, 59 mph at Togiak, 54 mph at Saint Paul, 53 mph at Sand Point, 47 mph at Saint Mary's, 43 mph at…

2. Jan 16, 2005Heavy Snow, Glacier Bay$40,000
   National Weather Service narrative

   A major overrunning precipitation event took place in Southeast Alaska during this time. In response to a low pressure system approaching the Panhandle from the southwest, an arctic front moved down through Lynn Canal on Saturday the 15th. This front ultimately stalled near a Cape Spencer-Petersburg-Hyder line. The flow aloft turned southerly and spread deep low level moisture up over this dome of arctic air in a classic overrunning pattern. The initial shot of heavy precipitation combined with the long duration overrunning, and resulted in a major winter storm in Southeast Alaska.Heavy snow occurred in the Stephens Passage, Icy Strait, Lynn Canal, and Misty Fjords regions#as well…

3. Feb 19, 1996High Wind, Glacier Bay$10,000
   National Weather Service narrative

   Strong westerly winds were reported from 2pm Monday through 8am Tuesday as a moderate low deepened to 988 mbs and moved southeast across Kodiak Island to 200 miles southeast of Kodiak Monday afternoon. Winds reached 82 mph on Monday. Trees fell on power lines, signs were blown away, a canopy was blown off a truck and a 28 foot cabin cruiser was blown off of its trailer.

5. Dec 16, 2004High Wind, Glacier Bay$2,000
   National Weather Service narrative

   A 971mb low, just off Cape Suckling, spread a strong front up through Southeast Alaska on this date. High winds were able to surface in most locations and resulted in extensive damage, power and phone outages. In Sitka, the roof was blown off an apartment complex, and a house boat sank in the harbor. In Juneau, a large tree fell into the roof of a home on Lena Point. The AMHS fast ferry Fairweather was severely damaged while returning from Haines to Juneau. Gale force sustained winds were occurring in Lynn Canal and wave heights were estimated to be near 12 feet. Most Alaska Airlines flights in and out of Southeast Alaska were cancelled. Large, mature Hemlock and Spruce trees were…

6. Apr 1, 1997High Wind, Glacier Bay$1,000
   National Weather Service narrative

   An intensifying low moved northward through the Gulf of Alaska to just south of Resurrection Bay at 3pm Tuesday. Central pressures were estimated close to 975 mbs early Tuesday afternoon. The low began to rapidly weaken and recurve eastward Wednesday. Strong east to northeast winds preceded the low Tuesday morning...reported as high as 62 mph at Middleton Island between 5am and 6am Tuesday and 63 mph very close to Cape Saint Elias between 6 and 8am Tuesday. By Tuesday afternoon...increasingly strong northwest winds on the back side of the low reached 86 mph in Kukak Bay (near Afognak Island just north of Kodiak Island) as reported by the Tug "Solution". In Kodiak, winds reached 51…

7. Feb 24, 1997High Wind, Eastern Chichagof Island$1,000
   National Weather Service narrative

   A strong, frontal 956mb low just south of Adak at 3pm Sunday curved northwest into the southwest Bering Sea...weakening to 964mbs 90 miles northeast of Shemya, along the extreme western Aleutian Chain. Brisk southerly winds, from 40 to locally 55 mph, were observed in a tight semicircle around the southeast side of the low. Stronger southeasterly winds, however, preceded the front...which elongated east and northeast...extending in an arc through Saint George Island and Cape Sarichef at 3am Monday. The front began weakening thereafter, extending in a long arc through the northern Bering Sea to Nunivak Island, across Port Heiden to 300 miles south of Kodiak 3pm Monday and in a long…

8. Mar 19, 2006Heavy Snow, Glacier Bay$1,000
   National Weather Service narrative

   A strong developing low from the north central Pacific Ocean deepened to the mid 980 MBs as it moved to Prince William Sound area through the 19th of March. As the associated weather front approached cold continental air from the interior was pulled to off shore over the panhandle. A wave developing on the front during the 19th helped stall the front offshore the panhandle region, leaving the heaviest precipitation amounts to fal over the coastal and northern panhandle regions, before warm air from the south made its way into the northern inner channels. Yakutat WSO reported a total snowfall of 22.5" from the event. Other notable snow amounts were 15.6" from the COOP site at…
