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.
