Tropical Depression Nine (2000)

Tropical Depression Nine of the 2000 Atlantic hurricane season was a weak tropical cyclone that lightly affected parts of the Gulf Coast. Developing on September 8 from the interaction of a persistent low-level trough and a cluster of convection associated with a tropical wave, the depression reached peak winds of 35 mph that same day. The depression was short-lived, weakening just prior to landfall near Sabine Pass, Texas on September 9. Over land, it rapidly degenerated into a remnant low. Despite being a weak storm, squalls to the east of the center generated tropical storm-force gusts over open water, and dropped moderate to heavy rainfall throughout the western Gulf Coast.

Meteorological history
The origins of Tropical Depression Nine are from the interaction of a persistent low-level trough and a cluster of convection associated with a tropical wave. The system moved north-northwestward from the Yucatan Peninsula, and on September 8 an ill-defined low-level center formed about 180 mi south of Lake Charles, Louisiana. Surface observations estimate that a tropical depression formed at 1800 UTC that same day. With a broad circulation, the depression was predicted to move ashore near Cameron, Louisiana within 8–10 hours. Due to the storm's close proximity to land, it never managed to strengthen beyond winds of 35 mph. The depression remained fairly disorganized, and late on September 8, ship reports indicated the possibility that two low-level centers existed within an elongated low pressure system; one center was located at 26.5°N 93.5°W, while the main was situated closer to the area of deep convection. Tracking northward at 12 mph with a minimum central pressure of 1007 mbar (hPa; 29.74 inHg), the closed circulatory center dissipated, and the depression weakened just at or before landfall. The weak low moved ashore near Sabine Pass, Texas at 1000 UTC on September 9, and rapidly dissipated over land.

Impact
Despite being a weak storm, associated squalls to the east of the center produced gusts up to tropical storm-force. A 45 mph gust was reported at buoy 42001, and buoy 42041 reported a 40 mph gust. The depression dropped heavy rainfall throughout portions of Texas, Louisiana, Mississippi and Alabama, peaking at 6.70 in at Buras, Louisiana. Waveland, Mississippi reported 6.56 in, and 6.30 in of rain fell on Dauphin Island, Alabama. Light rainfall was reported as far north as Arkansas and Kentucky and as far east as Florida. As a result of the rain, flash flood watches were posted for parts of Louisiana.
