Tropical Depression Nine formed over the northwestern Gulf of Mexico from the interaction of a persistent low-level trough and a cluster of convection, associated with a tropical wave, that moved north-northwestward from the Yucatan Peninsula. A poorly-defined low level center formed about 160 n mi south of Lake Charles, LA, on 8 September (Table 1 and Figure 1). Surface observations indicate the center moved north-northwestward and crossed the Gulf coast near Sabine Pass, TX around 1000 UTC 9 September. The cyclone dissipated over land later that day.
Squalls with gusts to tropical storm-force occurred well to the east of the center. These produced a 39 kt gust at buoy 42001 at 2100 UTC 8 September, a 35 kt gust at buoy 42041 at 2200 UTC that day, and a 34 kt gust at the Southwest Pass C-MAN station at 2000 UTC that day. Rainfall associated with the cyclone affected portions of Louisiana and Mississippi. There are no reports of damage or casualties.
