A persistent plume of moisture from the tropics inundated the Permian Basin/Big Bend and South Plains region of West Texas during late June and early July of 2010. Additional tropical moisture from Hurricane Alex created torrential rainfall in the Lubbock area from late on July 1st through early morning of July 4th. WTM stations in Terry, Lubbock, Garza, and Lynn Counties exceeded 9 inches with a peak total at the O'Donnell station of over 10 inches. Substantial urban and field flooding closed roads in the Lubbock, Ropesville, Wolfforth, Post, and Brownfield communities. Rapid rises in the Brazos River basin occurred on July 4th with road closures on two main roads in Garza County due to river flooding and Highway 87 in Lynn County due to field/draw flooding. A four-foot rise was reported at White River Lake (Crosby County) with an eight-foot rise in water levels at Lake Alan Henry (Garza County).
