Throughout the morning of September 19, Imelda caused widespread flooding to southeast Texas and the Houston Area, causing many of the local bayous to overtop their banks and flood residential areas. More than 1,000 people have been rescued from floodwaters. All bus and rail services have been temporarily shut down in Houston. A roof of a United States Postal Service building collapsed, leaving three people with minor injuries. George Bush Intercontinental Airport closed for about 90 minutes due to flooding on the runways, canceling 655 flights. Over 38 inches (97 cm) of rain fell in Beaumont. 41.81 inches (106.2 cm) inches of rain were reported on I-10 between Winnie and Beaumont, with nearly 30 inches (76 cm) falling in just 12 hours. Rain fell at over 5 inches (13 cm) per hour in several places. Floodwaters from the swollen Lou’s Bayou inundated Huffman on September 20, a day after the rains subsided. At least 50 people required rescue across the community. Throughout Houston, hundreds of homes were affected by flooding and more than 1,600 vehicles were towed. In Harris County alone, 422 people required high-water rescue; the Texas National Guard rescued 130 people. During the flood, nine barges escaped a shipyard, and at least two struck the Interstate 10 bridge over the San Jacinto River, causing visible damage to some of the columns supporting the highway. The bridge was subsequently closed to traffic in both directions.
