DISCUSSION AND OUTLOOK ---------------------- At 400 PM CDT (2100 UTC), the center of Tropical Depression Eight was located near latitude 26.1 North, longitude 90.7 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 surface observations is 1006 mb (29.71 inches). HAZARDS AFFECTING LAND ---------------------- Key messages for Tropical Depression Eight can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDAT3 and WMO header WTNT43 KNHC. WIND: Tropical Storm conditions are expected in the warning area by Friday night or Saturday morning. Tropical storm conditions are possible within the watch area by Friday night or Saturday morning. RAINFALL: The tropical depression is expected to produce 3 to 5 inches of rain with isolated maximum totals of 10 inches through Monday along the Gulf Coast of the United States from Louisiana to south Texas, and inland to the Mexican states of Coahuila, Nuevo Leon, and northern Tamaulipas. 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 in a day or two. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office.
