 A freight train overturned on waterlogged tracks Saturday morning in Texas as heavy rains pounded the region for a third straight day — with remnants of Hurricane Patricia threatening to keep a large part of the state under a flash flood watch. The remnants of Patricia, which was downgraded to a tropical depression and was expected to reach northern Mexico by Saturday night, may add to the rain falling in South and Central Texas, said Jesse Moore, a National Weather Service forecaster in Fort Worth. In San Antonio, a man walking his dog before dawn early Saturday was swept into a flooded drainage ditch and disappeared, fire officials said. The dog was found, but firefighters had to suspend the search for his owner due to the weather. A Union Pacific freight train derailed before dawn on Saturday near Corsicana, about 50 miles south of Dallas, because a creek overflowed and washed away the tracks, said Jeff DeGraff, a railroad spokesman. Both crew members "swam to high ground" and were pulled out by a high-water rescue team, DeGraff said. "A Navarro County rescue team was able to get in and pull them to safety, they are back safe on dry ground." Union Pacific spokesman Jeff DeGraff told the station that one locomotive and several rail cars were partially submerged, but no one was injured. Authorities on Saturday morning reopened a section of Interstate 45 near Corsicana that was closed overnight due to flooding, backing up traffic for 12 miles. He said that the county had received 20 to 21 inches of rainfall in the past 24 hours, and said authorities had performed 72 swift water rescues. Flight tracker flightaware.com reported that about 100 Saturday flights had been canceled at Dallas-Fort Worth International Airport. A flash flood watch was in effect for the Waco, Austin, San Antonio, Corpus Christi, Laredo and Brownsville areas through Sunday morning, according to the National Weather Service. Strong thunderstorms dropped more than 7 inches of rain across Dallas-Fort Worth, NBC Dallas-Fort Worth reported, with flash flood watches and warnings in effect in many places until Sunday. The remnants of Patricia — which made landfall Friday evening in southwestern Mexico as a Category 5 storm — are expected to reach Texas by Saturday night and exacerbate the flooding, forecasters said. ___

– Two crew members had to be rescued when flooding in Texas overturned a 64-car Union Pacific freight train on its way to Houston early Saturday morning, NBC News reports. Navarro County, where the train was derailed around 3:30am local time, had received nearly 2 feet of rain in 24 hours, and more was expected with what's left of Hurricane Patricia heading into the area. According to the AP, a creek overflowed and washed away the train tracks. "[The crew] escaped the train after it stopped and swam to high ground," a Union Pacific spokesperson tells the AP. "A Navarro County rescue team was able to get in and pull them to safety. They are back safe on dry ground." Despite several rail cars and a locomotive ending up partially underwater, no injuries were reported in the train crash, NBC reports. The train—which is carrying cement or gravel—was still on its side hours later, with crews waiting until water levels drop before they attempt to remove it. After three days of heavy rains, Navarro County has carried out five dozen water rescues. According to the AP, only one person is missing so far in the recent Texas flooding. A man walking his dog in San Antonio fell into a flooded draining ditch and was swept away. His dog was later found safe.
