Catastrophes · Inondations dans le delta du YukonLa montée des eaux côtières menace d’inonder les routes menant à la piste d’atterrissage de Hooper BayRédigé 23 octobre 2026 à 08:10 UTCRegarderTranscription0:07Flood water threatens Hooper Bay's roads to the airstrip.0:10Low buildings and beach property are expected to flood, along with larger parts of0:14town.0:14The immediate question is whether the predicted flooding will cut off people's0:18access to the airstrip.0:19Hooper Bay faces the greatest expected impacts within the Yukon Delta Coast warning0:24in western Alaska.0:25The forecast singles out this community for higher water levels than the rest of the0:29coast, putting its low buildings and airstrip roads at particular risk.0:33The warning zone also includes Kotlik, Chevok, Scammon Bay, Emmanuel, Mountain0:38Village, Newnham Equa, and Alakanook.0:41Those communities share the coastal warning area, but Hooper Bay has its own higher0:45forecast range.0:46The warning doesn't predict identical flooding in every community.0:49Hooper Bay's forecast is 5 to 7 feet above the normal high tide line.0:53Elsewhere along the Yukon Delta coast, the forecast is 2 to 4 feet above that same0:58line.0:58Both ranges describe the water level expected during the flood period.1:02A house's elevation determines how much water reaches it.1:05The same goes for a road.1:065 to 7 feet above normal high tide doesn't tell a resident how deep water will be at1:10their doorstep.1:11Lower ground can flood while higher ground stays above the water.1:14Roads linking town to the airstrip are among the places expected to flood.1:18Water could also reach beach property and the lowest buildings.1:22That makes the reach of the water important for both property and movement through1:25the community.1:26People could lose their route to the airstrip if those roads become impassable.1:30A runway's condition is a separate issue.1:32The forecast identifies a threat to reaching the airstrip, so road access will be1:36one of the important conditions to check as flooding begins.1:40South to southeast wind gusts could reach up to 65 miles an hour Friday.1:44That's a possible gust in the forecast.1:46The coastal water levels are also predictions for the approaching flood period,1:50which begins Friday morning.1:51The forecast has narrowed since October 20th.1:54The earlier outlook put possible water levels at 4 to 8 feet above normal high tide1:58in Hooper Bay.1:59The October 22nd warning calls for 5 to 7 feet expected.2:03Both describe this approaching event.2:05The flood period runs from 4 Friday morning through 10 Sunday night.2:09Alaska Daylight Time, October 23rd through 25th.2:12The warning's written timing and its encoded flood event interval both carry that2:15same Sunday night end.2:17A separate exploration field carries a much shorter time.2:20It gives 7 Friday morning, just three hours after the forecast onset.2:24The bulletin's zone header carries that shorter time too.2:26Why that field ends so early hasn't been explained.2:29The flood event end is 10 Sunday night.2:32The separate exploration field says 7 Friday morning.2:35The shorter timestamp doesn't mean the flood danger ends Friday.2:38The warning itself keeps the hazard window open through Sunday night.2:42Hooper Bay has already experienced floodwater dividing access within town.2:46A state assessment published in 2021 documents an earlier event with a different2:50pattern from the one now forecast.2:52That history shows why the location of flooding matters alongside its height.2:55On September 16th, 2016, floodwater cut off access across the town center while the3:00airport road remained mostly above water.3:03The current forecast specifically threatens the airstrip roads as well as larger3:06parts of town.3:07Whether those roads will actually become impassable is still unknown.3:10Actual water levels, road access, and any official protective orders will determine3:14the consequences for residents.3:16The forecast puts low buildings and access to the airstrip at risk through Sunday3:19night.Lire l’articleChronologie de l’histoireHeyDexLe format court ↗
