The depression is moving toward the northeast near 16 mph (26 km/h), and this motion is expected to continue with a decrease in forward speed through Sunday night. On the forecast track, the center of Delta should move across western and northern Mississippi today and into the Tennessee Valley tonight and Sunday. Maximum sustained winds have decreased to near 35 mph (55 km/h) with higher gusts. Additional weakening is expected, and Delta is expected to decay to a remnant low pressure area on Sunday. Greenwood, Mississippi, recently reported a wind gust of 43 mph (69 km/h), and an automated station near Monticello, Arkansas, recently reported a wind gust of 41 mph (66 km/h). The minimum central pressure estimated from surface observations is 994 mb (29.36 inches). HAZARDS AFFECTING LAND ---------------------- Key messages for Delta can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDAT1, WMO header WTNT41 KNHC, and on the web at www.hurricanes.gov/text/MIATCDAT1.shtml. WIND: Wind gusts to tropical-storm force are possible this afternoon over portions of northern Mississippi and southeastern Arkansas. STORM SURGE: Water levels will continue to subside today along the Louisiana coast. Consult products issued by your local National Weather Service forecast office for additional information. RAINFALL: For eastern Arkansas and northern Mississippi, Delta is expected to produce an additional 2 to 4 inches of rain, with isolated storm totals of 10 inches. These rainfall amounts will lead to flash, urban, small stream, and minor river flooding. As the remnants of Delta move further inland, 1 to 3 inches of rain, with locally higher amounts, are expected in northern Alabama and the Tennessee Valley into the Mid-Atlantic through the weekend. There is a potential for 3 to 6 inches in the Southern to Central Appalachians, which could lead to flash, urban, small stream, along with isolated minor river flooding. TORNADOES: A few tornadoes are possible across parts of Alabama, the Florida Panhandle, and western Georgia through early tonight. SURF: Swells from Delta are gradually subsiding along the northern Gulf coast. Please consult products from your local weather office for additional information.
