DISCUSSION AND OUTLOOK ---------------------- At 100 PM CDT (1800 UTC), the center of Tropical Depression Eight was located by an Air Force Reserve Hurricane Hunter aircraft near latitude 26.0 North, longitude 90.3 West. The depression is moving toward the west-northwest near 7 mph (11 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 today and Friday and make landfall along the Texas coast on Saturday. Maximum sustained winds are near 35 mph (55 km/h) with higher gusts. Slow strengthening is expected, and the depression could become a tropical storm during the next 12 to 24 hours. The latest minimum central pressure reported by the Hurricane Hunter Aircraft is 1008 mb (29.77 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 possible within the watch area by Friday night. RAINFALL: The tropical depression is expected to produce 3 to 5 inches of rain with isolated maximum totals of 8 inches through Monday along the Gulf Coast from Louisiana to the Lower Texas Coast, and inland through south-central Texas and the Rio Grande Valley. This rain may result in flash flooding, rapid rises on small streams, and isolated minor flooding across the west-central Gulf Coast and into portions of south Texas. SURF: Swells generated by the depression 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.
