The unusually wet storm pattern that dropped several inches of rain around the county since last Friday -- causing an onslaught of flooding, power outages and traffic accidents -- moved out of the region overnight, according to the National Weather Service.Preliminary seven-day rainfall totals as of late Wednesday afternoon were: 6.74 inches at the Oceanside Airport; 6.79 in Vista; 5.84 in Encinitas; 5.42 at the Montgomery Field; 4.32 at San Diego Lindbergh Field; 4.59 in National City; 8.74 in Fallbrook; 8.3 in Escondido; 6.45 in Poway; 10.04 on Mount Woodson; 7.99 at the Ramona Airport; 6.61 in Santee; 6.27 in Alpine; 18.23 on Palomar Mountain; and 10.9 in Santa Ysabel.Thursday's NWS forecast calls for partly cloudy skies in the morning, followed by mostly sunny skies with light winds. Also, light winds were expected.The mercury Thursday is expected to top out in the low 60s along the coast and western valleys, high 50s near the foothills, mid-50s in the mountains and mid-to-high 60s in the deserts.Steady overnight and morning drenching Wednesday caused the San Diego River to overflow and the Tijuana River to likewise swell past its banks in the far southern reaches of the county.By midday Wednesday, Qualcomm Stadium's playing field and much of its huge parking lot were submerged in muddy flows. Several miles away, about 50 people were trapped by waters that deluged the Premier Inn on Hotel Circle Place, just south of Interstate 8.At 9 a.m. Wednesday, the San Diego River was more than two feet above flood level, according to the National Weather Service.Lifeguards used inflatable rescue vessels to evacuate the stranded vacationers and employees, some of whom reported non-life-threatening health problems, including trouble breathing and issues with diabetes and heart disease. Several pregnant women also were among those trapped at the drenched lodge.The boats were attached to a nylon tether that emergency personnel pulled back and forth across the swollen river, whose flows were so powerful they washed a few commercial garbage bins away, said Maurice Luque, a spokesman for the San Diego Fire-Rescue Department.Medics transported two of the evacuees to a hospital to be checked out.Other structures swamped by floodwaters in Mission Valley Wednesday included the Handlery Hotel, Town and Country Resort Hotel and a number of condominiums, according to police.City public safety personnel also came to the rescue of people trapped by rising waters in Sorrento Valley, San Diego lifeguard Lt. Andy Lerum said.Heavy rains in the North County formed a small lake behind the Helen Woodward Animal center in Rancho Santa Fe Wednesday."We've kept the animals safe and dry; the ones in kennels, smaller animals, puppies... those are now inside," said Trisha Lord St. George, who works at the center.A huge irregularly-shaped sinkhole formed on a private driveway on the outskirts of Fallbrook. Homeowner Sarah Schaeffer said it began to crumble at about 2 a.m.Schaeffer said about four hours later, another storm front passed through and the sinkhole grew larger."It took out 15 fence posts," she said. "They were dropping by the minute, like Niagara Falls."In rural areas around the Tijuana River, which also breached its banks Wednesday morning, ranchers and other livestock owners had been urged earlier in the week to move their animals and families to higher ground. Despite the flooding in those areas just north of the Mexican border, no serious problems were reported.Some Poway residents woke up to flooded homes on Wednesday.Homeowner Leonardo Ruiz said his home was completely flooded and everything that wasn't up off the ground was ruined."We do have flood insurance," said Ruiz. "I hope that insurance will pay for everything we lost because we couldn't save nothing."Ruiz's neighbor, Doug Stampfli, said he was able to protect his house with cinderblocks and sandbags."We did what we could, fortified our space... and friends helped us," he said.Stampfli said nearby Rattlesnake Creek the problem because the city of Poway never widened the section of creek that runs by his house."The water hits that narrow channel and it boils, then it drops the silt and it backs it up all the way back to the city of Poways train bridge," said Stampfli. "The city just needs to either change the course of the creek or clean it out. There's cattails over there and everything else."For now, Stampfli said he is just grateful his sandbags and cinderblocks are holding."Barely yeah, just barely, but they are working," he said.The squalls have dumped upwards of 6 1/2 inches of moisture along the coast, more than 8 inches in some inland valley communities and in excess of 13 inches in certain mountain locales, according to the weather service.The relentless showers harried motorists for yet another day, along with commuters who rely on mass transit.Coaster and Amtrak train service between Oceanside and San Diego were canceled for the day due to flooding in Sorrento Valley and storm debris in Encinitas. Crews will have to wait for the water to recede so they can inspect the tracks for safety, according to Alex Wiggins, a spokesman for North County Transit District.The downpours also disrupted San Diego Trolley service Wednesday. Tracks used by its Green Line runs were under several inches of water at Interstate 15 in the early afternoon, forcing the Metropolitan Transit System to use buses to ferry the affected commuters between the Grantville and Qualcomm Stadium stations.Rails shared by the Green and Orange lines, meanwhile, were blocked by mud slides near the El Cajon Transit Center. Riders were being bused east to Santee, MTS spokeswoman Judy Leitner said.The storm also resulted in partial or full closures of dozens of roadways.
