بلایای طبیعی · Charleston tidal floodingCharleston coastal flooding: Warning cancelled, more morning flooding forecastمکتوب ۵ آبان ۱۴۰۵ ساعت ۰:۲۹ (UTC)تماشامتن پیادهشده0:07Saltwater flooded Charleston streets ahead of two more mornings of forecast0:10flooding.0:11Monday's warning has ended, but Tuesday and Wednesday's high tides still threaten0:15flood, prone roads and morning commutes.0:17The immediate question is which risks ended with that warning and which ones carry0:21into the next commute.0:22Water covered Broad Street at Lockwood on Monday, October26.0:25That confirms street flooding.0:27Nobody has confirmed an observed harbor peak showing Charleston reached major flood0:31stage, which had been forecast as a possibility around the morning high tide.0:35Forecasters expected numerous roads to become impassable and warned that properties0:39could flood.0:39Downtown commuters faced the possibility of closures around high tide, with routes0:44unavailable until water receded.0:46Those forecasts described the danger people faced, rather than a count of roads0:49closed or homes damaged.0:51The warning ended at ten twenty nine Monday morning.0:54Charleston and Coastal Carleton had moved from an overnight watch to a warning0:57earlier that morning.0:58Sunday's separate evening advisory had been scheduled through ten that night.1:02Its schedule belongs to Sunday.1:04The warning covered five to eleven Monday morning and was cancelled thirty one1:08minutes early.1:08Sunday's bulletin also carried a ten forty-five message expiration time.1:12That administrative timestamp didn't add forty-five minutes to the forecast flooding1:16period.1:17The hazard scheduled end was ten Sunday night.1:19Monday's warning forecast one to two feet of salt water above ground along1:23shorelines and tidal waterways.1:25Charleston's total water forecast was seven point nine to eight point one feet on a1:29tide.1:29Gauge reference scale.1:31That higher number describes water elevation relative to a reference level.1:35That reference is called mean lower low water, a standard based on the lower daily1:39low tides.1:40Forecast water elevation and water depth over land answer different questions.1:44How much water reaches a particular road also depends on the road's elevation.1:47Coastal Georgetown's advisory was scheduled through ten Monday morning.1:51Beaufort and Tidal Berkeley had eleven o'clock scheduled endings.1:54Charleston and Coastal Carleton had the stronger warning.1:56Those were morning alert schedules and shouldn't be carried forward as Monday2:00evening's alert status.2:01Southern Berkeley, including Daniel Island, had a six two eleven morning advisory2:06forecasting up to half a foot of inundation.2:08Charleston and Coastal Collitons1,2 ,2 foot forecast covered different locations.2:14A lower forecast in Berkeley reflects different expected impacts across the coast.2:17Strong onshore winds pushed water toward the coast while astronomical tides were2:21exceptionally high.2:22A wedge of high pressure helped produce both the pleasant weather and the coastal2:26winds.2:26Sunny skies across the low country could still leave a coastal route underwater.2:30The forecast put minor saltwater flooding around Sunday seven fifty-six evening high2:34tide.2:34Monday's eight eighteen morning tide carried the greatest expected impact.2:38With major flooding possible, strong northeast flow was still expected through early2:42week, sustaining a multi-ditoastal flooding threat.2:44Tuesday's high tide arrives at nine o six in the morning.2:47Wednesday's is forecast for nine fifty-seven.2:50Both mornings carry a forecast of moderate coastal flooding, with further road2:53closures possible in flood-prone areas during the commute.2:56Tuesday's astronomical tide prediction is six point nine feet above mean lower low3:00water.3:00The same tide is also expressed as one point one feet above mean higher high water,3:05a reference based on the higher daily high tides.3:07Those two figures describe the same predicted astronomical tide using different3:11reference levels.3:12Wind can push the actual water higher.3:14Comparing Tuesday's astronomical prediction with Monday's total, water forecast3:18would mix two different measures and wouldn't tell you how much conditions have3:21improved.3:22The flood warning cancellation also left separate ocean hazards on their own3:26schedules.3:26Rough surf carried risks of difficult boating conditions and beach erosion,3:30alongside the danger from rip currents.3:32Rough ocean conditions can persist after a road.3:35Flood warning ends.3:36For coastal Colton and Charleston, the cancellation bulletin kept the high surf3:40advisory's scheduled afternoon ending and the high rip, current risks evening ending3:44separate from the cancelled flood warning.3:48The surf advisory was scheduled through two this afternoon.3:51That scheduled ending has passed.3:53The high rip current risk runs until eight tonight.3:56People heading to the beach still need to follow the separate ocean.3:59Hazard information.4:00For the next commute, Charleston's Tide Eye and City Flood Road Closure Resources4:04provide places to check current road conditions.4:06Check before choosing a route, and don't assume a previously flooded road has4:10reopened.4:11A water-covered road shouldn't become a shortcut.4:13Winds are forecast to ease somewhat by midweek, with conditions beginning to improve4:17by the end of the work week.مقاله را بخوانیدخط زمانی
