A Tropical Storm Watch means that tropical storm conditions are possible within the watch area, generally within 48 hours.

For storm information specific to your area, including possible inland watches and warnings, please monitor products issued by your local National Weather Service forecast office. DISCUSSION AND OUTLOOK ---------------------- At 700 PM CDT (0000 UTC), the center of Tropical Depression Eight was located near latitude 26.1 North, longitude 91.0 West. The depression is moving toward the west-northwest near 8 mph (13 km/h), and a west-northwestward to westward motion is expected during the next couple of days. On the forecast track, the center of the depression is expected to move across the northwestern Gulf of Mexico tonight and Friday and make landfall along the Texas coast on Saturday. Maximum sustained winds are near 35 mph (55 km/h) with higher gusts. Strengthening is expected during the next 48 hours, and the depression is expected to become a topical storm tonight. The estimated minimum central pressure based on data from the NOAA Hurricane Hunters is 1003 mb (29.62 inches).

This rain may result in life-threatening flash flooding, rapid rises on small streams, and isolated minor-to-moderate river flooding. SURF: Swells generated by the tropical cyclone are expected to increase and affect much of the Texas and Louisiana coasts during the next few days. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office.
