Tropical Storm Harvey emerged back over the Northwest Gulf of Mexico during the morning hours of August 28th, and intensified slightly as drifted northwest just off the Southeast Texas coast, eventually making a 3rd landfall near Cameron, Louisiana during the early morning hours of August 30th. After Harvey made landfall in far Southwest Louisiana during the early morning hours of August 30th, the more concentrated bands of heavy rain were concentrated on the northwest side of the center, which slowly drifted northeast into Central Louisiana during the afternoon and evening hours. Thus, more significant reports of flash flooding were received across Deep East Texas and Westcentral Louisiana, before drier air had begun to wrap around the center, thus reducing rainfall rates as the center moved into Northeast Louisiana during the early morning hours of August 31st. In addition to the widespread flooding, reports of downed trees and power lines were received over portions of Deep East Texas and Northcentral Louisiana, as some of the stronger squalls produced wind gusts to 35-40 mph with locally higher gusts atop already saturated grounds.
