Heavy rainfall over a small multi-county area in southwestern Oklahoma helped produce a significant flood event on October 7. During this period an upper level storm system and associated warm front located along the Red River valley generated a large complex of thunderstorms near and along the front in western north Texas and southwestern Oklahoma.The thunderstorms dropped precipitation at a rate of 1-2 inches per hour, with the heaviest accumulations falling in a 12-hour period between midnight and noon on October 7 along with some hail and strong wind gusts. The area where the highest totals occurred included eastern Greer, northern Kiowa, southern Washita, southern Caddo, northern Comanche, and northwestern Grady counties. Storm total rainfall amounts ranged from 2 to 4+ inches, with an isolated area of 4.5 to 7 inches observed over northwestern Kiowa County.The highest storm total rainfall reports ranged from 2.5 inches to near 7 inches. These measured totals include: Lone Wolf - 6.50 inches; Gotebo 9S - 5.00 inches; Altus-Lugert Dam - 4.97 inches; Hobart Airport - 4.87 inches; Altus Lake Project Office - 4.39 inches; Apache 4ENE - 4.37 inches; Stecker 5S - 4.21 inches; Stecker 3SSE - 4.08 inches; Cyril 3WNW - 3.94 inches; Stecker 2E - 3.81 inches; Cement 3WNW - 3.53 inches; Stecker 5E - 3.40 inches; Sedan - 3.32 inches; Cement 4N - 3.11 inches; Anadarko 3E - 2.92 inches; Anadarko 1NE - 2.91 inches; Fletcher 3NNW - 2.73 inches; and Roosevelt - 2.56 inches.
