Houston ChronicleDALLAS (AP) — The latest on Texas storms, flooding and preparations for remnants of Patricia as the hurricane that hit Mexico lost strength and became a tropical depression: (all times local): Galveston County Judge Mark Henry has issued a voluntary evacuation for Bolivar (BAW'-luh-vuhr) Peninsula as forecasters predict 8-12 inches of rain for the area and tides that are 4 to 5 feet high. In a statement Saturday, the judge warned area residents they might find themselves isolated as the heaviest winds and rains comes ashore. Henry says the intention of the voluntary evacuation order is to alert residents that emergency responders may be unable to reach them. Police say water covered a roadway, the man's car became trapped in the water and the vehicle began floating. The Texas Department of Transportation says southbound I-45 reopened around 6 a.m. CDT Saturday, with the northbound stretch opening about 2½ hours later. Forecaster Jesse (JES'-ee) Moore says remnants of Tropical Storm Patricia, which made landfall Friday in Mexico as a hurricane, are expected to send more rain into parts of Central and South Texas through the weekend. TxDOT spokesman Tony Hartzel says northbound I-45 remained closed, in the Fairfield area, to avoid traffic delays father north near Corsicana, where more than a foot of rain caused flooding. The National Weather Service says a flash flood watch remains in effect for the Dallas, Fort Worth, Waco, Austin and San Antonio areas through Sunday morning. Forecasters say Houston and Galveston remain under a flash flood watch through Monday morning, with possible coastal flooding concerns.
