There was continuing rainy pattern that had been in place for a week or more. A wide swath of showers and thunderstorms developed in the coastal waters just south of Louisiana coast. As those storms moved northward within a very moisture rich atmosphere, they were both enhanced by the seabreeze boundary located across the City of New Orleans and slowed in progression. This resulted in flash flooding in portions of Jefferson and Orleans parishes.
