1. Water levels will continue to subside today along theLouisiana coast. Consult products issued by your local NationalWeather Service forecast office for additional information.

2. Tropical-storm-force wind gusts will persist for a few more hours over portions of northern Mississippi and southeastern Arkansas.

3. Heavy rainfall will lead to flash flooding and minor river flooding across portions of the Lower Mississippi and Tennessee Valleys today, and into the Southern Appalachians through Sunday. Minor to major river flooding will continue across portions of Louisiana and Mississippi though much of next week.

There are no coastal watches or warnings in effect.

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 tropicalstorm 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 MidAtlantic 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.

At 1000 AM CDT (1500 UTC), the center of Tropical Depression Delta was located near latitude 33.1 North, longitude 90.8 West. 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).

Surface observations, Doppler radar data, and satellite imagery indicate that Delta has continued to weaken as it moves from northeastern Louisiana into western Mississippi. There are no recent surface observations of sustained tropical-storm-force winds in the areas where the radar data show the strongest winds are occurring, so based on this the initial intensity is reduced to 30 kt. It should be noted that wind gusts to tropical-storm force are still occurring over portions of northern Mississippi and southeastern Arkansas, and these should continue through this afternoon.The initial motion is now northeastward or 035/14. The flow between a mid-to upper-level ridge over the Gulf of Mexico and the mid-latitude westerlies over the United States should steer Delta or its remnants generally northeastward until the system dissipates. The new forecast track has only minor adjustments from the previous forecast, and it lies near the consensus models.Continued weakening is expected, and Delta is forecast to degenerate to a remnant low pressure area in about 24 h. The global models are in good agreement that the cyclone should weaken to a trough between 48-60 h, and the intensity forecast follows this scenario.This is the last advisory on Delta issued by the National Hurricane Center. Future information on this system can be found in PublicAdvisories issued by the Weather Prediction Center beginning at 4 PM CDT, under AWIPS header TCPAT1, WMO header WTNT31 KWNH, and on the web at http://www.wpc.ncep.noaa.gov.
