Thursday afternoon, Tropical Storm Erin made landfall near Lamar, Texas, (near Corpus Christi). Erin then moved northwest to inland Texas and became a tropical depression. It moved slowly north just east of Lubbock and then to Childress by Saturday morning.
By late Saturday the weak circulation system of Erin was over southwest Oklahoma. During the day Saturday, widespread rainfall had been occurring across western Oklahoma with isolated activity in central sections. During the overnight hours convection intensified in western Oklahoma and a circulation pattern redeveloped. This circulation pattern was noted by the surface pattern from the Oklahoma Mesonetwork and indicated a “closed circulation.” Additionally, an “eye” feature formed over Blaine County and tracked east during the night. This feature dissipated Sunday morning over Lincoln County. Sustained winds of 35-40mph were noted in Blaine and Caddo Counties with 50-60 mph gusts in these same areas. These gusts continued for over an hour. Along with the strong winds, excessive rainfall fell near the “eye” feature, producing widespread flooding. The remnants of Erin tracked across Oklahoma near I-40 into Arkansas during the day.
Wind damage was reported in several areas of western Oklahoma and some tornado reports were received. Flooding was the main impact with several counties experiencing significant flooding. The most noted is Kingfisher where all major national media outlets carried a dramatic rescue this afternoon. Widespread rainfall amounts of 4-7 inches occurred with isolated amounts near 10 inches.

I’m working on the RADAR above, it should loop but won’t. I think Google has changed something on the code.
