The young autumn's first cooling front arrived late on October 5th. Preceding the front, a rapidly developing cluster of strong thunderstorms formed in Willacy and Cameron County, aided by interaction with the sea breeze. Torrential rains of nearly 4 inches in an hour in Brownsville just west of downtown created localized flash flooding, with more nuisance urban flooding in other parts of the city.
