DISCUSSION AND OUTLOOK ---------------------- At 1000 PM CDT (0300 UTC), the center of Post-Tropical Cyclone Beta was located near latitude 29.1 North, longitude 95.4 West. The post-tropical cyclone is moving toward the northeast near 8 mph (13 km/h) and this motion is expected to continue through the next 48 hours. Maximum sustained winds are near 30 mph (45 km/h) with higher gusts. Little change in strength or slow weakening is forecast during the next 48 hours. The estimated minimum central pressure is 1007 mb (29.74 inches). HAZARDS AFFECTING LAND ---------------------- RAINFALL: For the upper Texas coast, additional rainfall of 4 to 8 inches with isolated storm totals up to 20 inches is expected. Significant flash and urban flooding is occurring and will continue overnight . Minor to isolated moderate river flooding is ongoing. Rainfall totals of 13 to 14 inches have been measured across portions of the Houston metropolitan area thus far. Rainfall totals of 2 to 5 inches are expected east into the Lower Mississippi Valley, portions of the Tennessee Valley, and the southern Appalachians through the end of the week. Flash and urban flooding is possible, as well as isolated minor river flooding on smaller rivers. SURF: Swells generated by a combination of Beta and a cold front over the northern Gulf of Mexico will continue along the coasts of Louisiana and Texas during the next couple of days. These swells are likely to cause life-threatening surf and rip current conditions. Information on ongoing coastal flooding can be found in coastal flood products issued by local National Weather Service offices.
