Gulf of Mexico:Post-Tropical Cyclone 26L (Delta)DELTA BECOMES A NON-TROPICAL LOW…HEAVY RAIN THREAT CONTINUES
Here’s what the computer models are showing
According to the NHC Advisory 25…The post-tropical cyclone is moving toward the northeast near 12 mph (19 km/h) and this motion is expected to become more east-northeasterly on Sunday. Maximum sustained winds are near 30 mph (45 km/h) with higher gusts. Weakening is forecast during the next 36 hours, and Delta’s surface low is expected to dissipate across West Virginia late Sunday night.
HAZARDS AFFECTING LAND
WIND: Wind gusts to tropical-storm force are possible prior to sunset over portions of Arkansas, Mississippi, and Alabama.
STORM SURGE: Water levels will continue to subside today along the Louisiana coast.
RAINFALL: In the Appalachian region of far northeast Georgia, the western Carolinas, and western Virginia, the remnants of Delta are expected to produce 3 to 6 inches of rain, which could lead to flash, urban, small stream, and isolated minor river flooding.
From northern Alabama and the Tennessee Valley into the Mid-Atlantic, 1 to 3 inches of rain, with locally higher amounts, are expected. Minimal hydrologic impacts are expected.
Moderate to major river flooding will continue across the Calcasieu and Vermilion river basins in Louisiana through much of next week.
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.
