The depression drifted northward until reaching Lufkin, Texas, where it stalled due to a high pressure system to its north.[2] While stalling over Texas, the storm dropped excessive rainfall, peaking at just over 40 inches (1,033 mm) in northwestern Jefferson County.[9] On June 7, the subtropical ridge off Florida weakened, while the ridge west of Texas intensified. This steered Tropical Depression Allison to make a clockwise loop, and the storm began drifting to the southwest. As the center reached Huntsville, Texas, a heavy rain band began to back build from Louisiana westward into Liberty County, Texas, which had caused additional flooding.[10] At the time, the system had a minimum central pressure of about 1004 mb and maximum sustained winds of about 10 mph (16 km/h).[11] Late on June 9 and early on June 10, Allison's remnants reentered reached the Gulf of Mexico and emerged over open waters.[12] The low once again became nearly stationary about 60 mi (100 km) south of Galveston, Texas, and despite more favorable upper-level winds, it showed no signs of redevelopment.[13] Due to dry air and moderate westerly wind shear, the storm transformed into a subtropical cyclone.
