Flash Flood — Orleans, LA

Sep 14, 2021

Tropical Storm Nicholas made landfall on the Texas coast south of Houston early Tuesday morning on September 14th. Over the next 24 hours, the weakening storm slowly tracked east-northeast along the coastline, reaching the LA/TX border Wednesday morning. During the 14th and 15th, outer bands of Nicholas expanded east across southeast Louisiana. The persistent rain from those banding features produced areas of flash flooding.
