DISCUSSION AND OUTLOOK ---------------------- At 400 AM CDT (0900 UTC), the center of Tropical Depression Laura was located near latitude 35.8 North, longitude 91.5 West. The depression is moving toward the northeast near 13 mph (20 km/h) and this motion is expected to become east-northeasterly during the day on Friday, with some acceleration expected Saturday and Sunday. Maximum sustained winds are near 30 mph (45 km/h) with higher gusts. Little change in strength is expected on Friday, with strengthening expected late Saturday into Sunday as Laura moves into the northwest Atlantic. The estimated minimum central pressure is 998 mb (29.47 inches). HAZARDS AFFECTING LAND ---------------------- RAINFALL: Through tonight, Laura is expected to produce the following additional rainfall totals: Northeastern Arkansas, northern Mississippi, northern Alabama, western and Middle Tennessee, southeastern Missouri, western and central Kentucky: 1 to 3 inches, with isolated totals of 5 inches. Southern Louisiana, southern Mississippi, and southern Alabama: 1 to 2 inches, with isolated totals of 4 inches. This rainfall will continue to cause isolated flash and urban flooding, small streams and creeks to overflow their banks, and minor to moderate river flooding. On Saturday, Laura is expected to produce 1 to 2 inches with isolated maximum amounts of 3 inches across portions of the central and southern Appalachians, and the Mid-Atlantic States. This rainfall may lead to flash and urban flooding and rapid rises on small streams. TORNADOES: The threat for a few tornadoes is expected to redevelop this afternoon into the evening across parts of the Mid-South and Tennessee Valley regions. SURF: Swells produced by Laura continue to affect the north-central and northeast Gulf Coast. These swells are likely to cause life-threatening surf and rip current conditions.
