Juneau, Alaska storm history at a glance (last 12 months)
This free weather history for Juneau — home to about 32,000 residents, a consolidated city-borough (the City and Borough of Juneau) — draws on StormAuditor's consolidated public record: 10 wind and hail events within 25 miles of Juneau in the trailing 12 months — 9 wind and 1 hail.
Events combine NWS warning products, observed Local Storm Reports, station measurements and official NCEI records in one event table. Because they include warnings, and wind covers thunderstorm and non-thunderstorm wind alike, they measure something different from the NCEI entry counts in the history section below; the two are not comparable year to year.
Busiest days near Juneau by event count

- September 19, 2026 — 1 event incl. warnings · 1 wind

How these numbers are counted
The storm numbers on this page are counted in four different ways. Each answers a different question with its own size cutoffs, area and time span, so compare numbers within one group, not across groups.
- Storm days (latest hail and wind): A day in the last 12 months when at least one report within 25 miles of Juneau showed hail 0.75 in. or larger or wind of 45 mph or more (StormAuditor screening thresholds). Reports are NWS storm reports from spotters, the public and officials, plus weather-station gusts, which count from 50 mph. A warning on its own never makes a storm day. The latest and largest hail, the latest and strongest gust, and the storm-day table all use this record.
- Storm-date pages (NWS severe): A storm-date page is published only when at least one report or station gust within 25 miles of a city met the National Weather Service severe criteria (hail 1.00 in. or larger, or wind 58 mph or more), at least two separate observations were logged, and the day ranks among the most significant. A storm report that relays an airport weather station's reading (the same station, the same gust and the same time) counts once, as the station reading. Not every storm day gets a page; when one does, the page and the storm-day table show the same largest hail and strongest gust.
- Events (12-month counts): Events count NWS warnings, storm reports (wind 50 mph+, hail 0.75 in.+), station gusts (50 mph+) and NCEI entries within 25 miles of Juneau, tornado entries counted as wind. One event is one place on one day, counted separately for hail and for wind. A weather station or storm-report point counts once a day, at that day's highest reading, however many readings it filed; a place with hail and wind on the same day is two events. NWS warnings count once per county per day, and each NCEI entry once per place per day. A storm report that relays an airport weather station's reading (the same station, the same gust and the same time) counts once, as the station reading. The same report arriving through another feed (SPC or NCEI) is one record. Events measure how busy the area was, not whether a storm hit: one storm can bring warnings and reports from many places, so the busiest days by event count can differ from the storm days.
- NOAA history (since 2010): The official NOAA storm record (NCEI Storm Events) within 25 miles of Juneau from January 1, 2010 to the day before the 12-month window starts: hail 0.50 in.+, thunderstorm wind 40 mph+ and tornadoes. It is a separate, older record with its own "storm days" (days with any entry), so its counts are not compared with the 12-month numbers.
