كوارث · المدود العالية في كاليفورنيامياه المحيط قبالة كاليفورنيا مرتفعة بالفعل. والمدود القادمة تهدد ساحلاً أنهكته الأضراركُتب 25 أكتوبر 2026 في 5:10 ص UTCشاهدالنص المفرّغ0:07Ocean levels in Newport Beach are running 18 to 22 inches above predictions.0:11Forecasters expect significant coastal flooding along already damaged shores,0:16threatening low-lying homes, businesses, and critical infrastructure.0:19Morning high tides bring the immediate danger.0:22Where will those tides put communities and coastal access most at risk?0:25San Diego and Orange counties face the southern coastal flood warning starting0:29Sunday.0:30Farther north, the advisory covering the San Francisco Bay Shoreline, Monterey Bay0:34and Big Sur Coast has already begun.0:37Each region has its own timetable.0:39It's still Saturday evening in California.0:41The Southern warning starts at 5 Sunday morning and ends at 1 Thursday afternoon.0:46Shoreline erosion is also expected around the morning peaks.0:49Los Angeles, Ventura, Santa Barbara, and San Luis Obispo counties have an advisory0:54from Sunday morning through Thursday afternoon.0:56Forecasters expect significant to moderate beach erosion with isolated seawater1:01damage to structures possible.1:02Sonoma and Marin's separate surf zone advisory starts Monday morning.1:06The Bay, Monterey, and Big Sur advisory runs from Saturday morning through 31:10Thursday afternoon.1:11Sonoma and Marin's advisory ends at the same hour Thursday.1:14Rising water can push waves farther up beaches and cut off escape routes.1:18Southern beaches also face high rip current risk.1:21Vulnerable northern shoreline and tidal waterway areas could see up to 1.9 feet of1:26water above ground.1:27That's a forecast of local flooding depth.1:29The much larger southern tide figures measure water elevation against a tidal1:33reference level.1:34Newport Beach has activated its emergency operations center and is reinforcing sand1:38berms, preparing pumps and tide valves, and positioning resources in flood-prone1:42neighborhoods.1:43Its emergency preparations include an October 9th proclamation, well before this1:47weekend's outlook.1:48Newport Beach expects its most consequential peaks Monday through Wednesday1:52mornings.1:53The city's adjusted outlook gives 8.3 feet Monday, 8.5 feet Tuesday, and1:598.4 feet Wednesday.2:00Those are water elevations, not 8 feet of flooding inside homes.2:04The city says those adjusted heights are 1.8 feet above predictions that leave out2:08the unusually elevated ocean conditions.2:11Its October 22nd alert warned residents about the ocean already running higher than2:15expected.2:15La Jolla's astronomical morning predictions are 6.14 feet Sunday and 6.4 to 42:20Monday.2:21They reach 6.59 Tuesday, then 6.55 Wednesday and 6.3 Thursday.2:26That sequence leaves out the unusually elevated ocean conditions that could push2:30water levels higher.2:31The adjusted outlook puts Los Angeles, Orange, and San Diego coastal water levels at2:357.5 to 8 feet or higher.2:38La Jolla could exceed 8 feet.2:40Those elevations use an average low water baseline from 1983 through 2001.2:45Any record-breaking level is still a possibility, not a measured new record.2:48Scripps Pier surface water reached around 77 degrees Fahrenheit this year, against2:53an average maximum around 70.2:55On October 22nd, it was around 73 degrees, compared with a seasonal average of 66.3:01Water expands as it warms.3:02Southern California ocean levels have been running 1.25 to 1.75 feet above3:07astronomical predictions.3:09Water has stayed at least half a foot above predictions for months.3:12That elevated starting point leaves less room before a high tide reaches vulnerable3:16land.3:17The moon's orbit adds another contribution.3:19We're near peaks in the 18.6-year lunar node cycle and the 4.4-year lunar perigee3:24cycle.3:25Both involve changes in the moon's orbit that affect the forces producing tides.3:29A long-standing marine heat wave is separate from the developing El Niño influence3:33arriving from the eastern Pacific.3:35An El Niño-related Kelvin wave, a broad ocean disturbance, can also raise coastal3:39water levels.3:40Human-caused warming adds a longer-term background, about a foot of sea level rise3:45along California over 125 years.3:47Earlier flooding also drew power from swells associated with the remnants of3:51hurricanes Marie and Rachel.3:53Those tropical storm-related swells aren't expected this round, but the tides are3:57expected to be higher.3:59Earlier seawater tore up the Long Beach Peninsula's historic boardwalk and struck4:02homes.4:03Newport Beach's Balboa Peninsula endured days of flooding.4:07Long Beach's breakwater blocks western waves, but southern waves can reach a narrow,4:11badly damaged stretch.4:12Earlier waves in Dana Point damaged homes, destroyed decks, and tore through walls.4:16Erosion at Carlsbad State Beach closed the Tamarack Day Use parking lot to vehicles.4:21At the wedge, lost sand exposed rusted rods and concrete from old buried4:24infrastructure.4:25Those are existing vulnerabilities before the next tides arrive.4:28Newport Beach says 30 to 40 trucks have been moving sand from above Prado Dam to the4:33wedge.4:33The goal was 2,000 cubic yards by Saturday.4:36Thousands of sandbags have also been installed in vulnerable parts of Balboa Island.4:48The sand volume is a target.4:50Completion hasn't been confirmed.4:51Residents have practical decisions to make before the morning peaks, including where4:55to park and how to protect gaps in waterfront defenses.4:57The city urges waterfront and low-lying residents to inspect seawalls for gaps or5:02low points.5:03It recommends sandbags or temporary barriers for vulnerable areas.5:06and says residents should consider moving vehicles to higher ground before water5:10arrives.5:11Long Beach began dredging Alamitos Bay on October 20 and sending sand through a5:15large hose to the peninsula.5:17The city says visible beach has been added beside the 72nd place parking lot.5:21Repairs to the damaged boardwalk have also begun.5:30A cracked slope below Coast Highway near Crystal Cove has already forced road5:34restrictions.5:35Caltrans has secured emergency funding described as millions of dollars and is5:39placing four-foot-tall sand-filled barriers below the road to absorb wave energy.5:44Two of Coast Highway's four lanes remain closed near Crystal Cove.5:47The remaining lanes carry one direction each.5:50Near Point Mugu, water has undermined Highway 1 and crews are installing boulders5:54between the road and the waves.5:55The Crystal Cove southbound closure runs between Reef Point and Irvine Cove drives.6:00The next stabilization step is a supporting mound at the slope's base, reinforced6:04with large rocks to limit erosion and further movement.6:07Malibu crews have placed rocks and boulders along an already eroded shoreline ahead6:12of high tides.6:13Erosion has threatened vehicle access to Point Doom Beach.6:17Locally called Westward Beach, a coastal sinkhole also threatens a home.6:22On October 21st, surf was washing away shoreline at Zuma Beach and threatening6:26Westward Beach Road and the Sunset Restaurant.6:29That existing damage adds to the local risk under the Los Angeles County Advisory.6:33Metrolink will suspend Orange County line service between Laguna, Nigel, Mission6:38Viejo, and Oceanside from Monday, October 26th through Friday, October 30th.6:42The rider alert says no alternative transportation will be available.6:46That coastal segment faces a five-day interruption.6:49Metrolink announced the plan October 22nd, so commuters already face a changed work6:53week before the next flooding is measured.6:56The immediate coastal danger centers on Sunday morning's tides, followed by Newport7:00Beaches Monday through Wednesday peaks.7:02Actual flood depths and additional damage will depend on what those tides do7:06locally.7:07Still higher tides are anticipated around Thanksgiving, Christmas, and Martin Luther7:10King Jr.7:11Day.7:12Strong winter storms arriving during those seasonal peaks would increase the threat7:16to a coast that has already lost protective sand and suffered infrastructure damage.اقرأ المقالالتسلسل الزمني للقصةHeyDexالمقطع القصير
