Issued at 1100 PM AST Mon Sep 16 2024 000 WTNT42 KNHC 170238 TCDAT2 Tropical Depression Gordon Discussion Number 23 NWS National Hurricane Center Miami FL AL072024 1100 PM AST Mon Sep 16 2024 Gordon has become a little better organized this evening, with convection intensifying around the center-- a marked improvement from 24 hours ago. A pair of scatterometer passes from 00-01 UTC showed believable maximum winds of 25-30 kt, and 30 kt is chosen out of continuity from the last advisory. The depression has been creeping westward recently, estimated at about 3 kt. As mid-level high pressure builds to the northeast of the cyclone, the tropical cyclone should turn northward on Tuesday and move faster to the north-northeast for the next few days. A frontal wave currently seen about 10 degrees north of Gordon should also cause the cyclone to accelerate midweek as Gordon moves around that feature. The biggest change to the guidance this evening is that most are a bit faster, so the latest NHC prediction is trended in that way. Modest increases in low- to mid-level moisture around Gordon are shown in the model fields during the next couple of days. In combination with generally low shear during that time, these factors suggest that Gordon will be primed for a comeback, and the intensity guidance generally calls for it to become a tropical storm again around midweek. The low-shear conditions should last through late week, so the NHC forecast is nudged upward from 2-4 days, a touch below the model consensus. The shear could get rather prohibitive by day 5 so the intensity forecast is leveled off then, but considerable uncertainty exists at that time frame, with model guidance ranging from a depression to a category 2 hurricane.

Issued at 500 PM EDT Mon Sep 16 2024 000 WTNT43 KNHC 162037 TCDAT3 Potential Tropical Cyclone Eight Discussion Number 5 NWS National Hurricane Center Miami FL AL082024 500 PM EDT Mon Sep 16 2024 Scatterometer data earlier today showed a very elongated surface circulation with frontal features extending from the low, confirming the non-tropical structure of the system. In fact, current observations show a significant temperature and dewpoint gradient remains along the boundary. Based on radar data and surface observations, the poorly-defined low center is likely near the coast or just inland over northeastern South Carolina. Although it failed to develop a well-defined center and the necessary organization to become a tropical cyclone, the low has produced significant impacts today, with life-threatening flash flooding reported in portions of southeastern North Carolina and wind gusts in excess of 60 mph along the coast. Another band of heavy rainfall is currently moving onshore over the Cape Fear region, with heavy rains also spreading farther inland. Recent surface observations show the sustained winds have diminished below tropical storm force, and the initial intensity is lowered to 30 kt. The system is moving north-northwestward at about 6 kt. This motion will bring the system farther inland over the Carolinas tonight and Tuesday, where it is expected to quickly weaken and dissipate. Although the wind threat has subsided, heavy rainfall and flash flooding remain a serious concern for portions of the Carolinas. For more information on this system, see products issued by the Weather Prediction Center and your local National Weather Service office. Since the system is no longer producing sustained tropical-storm-force winds, the Tropical Storm Warnings for the Carolinas have been discontinued. Therefore, this will be the final NHC advisory on the system. Key Messages: 1. Additional considerable flash and urban flooding and minor river flooding is possible across southern North Carolina and northeast South Carolina through tonight. There is also a risk of isolated flash and urban flooding for the southern Mid-Atlantic region and southern Appalachians through Wednesday. 2. Gusty winds will continue along portions of the coasts of South Carolina and North Carolina into this evening.

WIND: Gusty winds are expected to diminish this evening along the coast of North Carolina. STORM SURGE: Water levels remain elevated along portions of the southeastern North Carolina coast and will begin to subside after the next high tide cycle. Refer to your local National Weather Service office for additional information. RAINFALL: The system will bring an additional 4 to 8 inches of rainfall, with isolated totals of 10 inches, across portions of southeast North Carolina into tonight. Across northern South Carolina and the remainder of North Carolina, 2 to 4 inches of rainfall, with isolated totals near 8 inches, particularly in the North Carolina Blue Ridge, are possible through Tuesday. Over southeast Virginia and the Virginia Blue Ridge, expect 2 to 4 inches of rainfall, with locally higher amounts, tonight through Wednesday. This rainfall brings a risk of flash and urban flooding and minor river flooding. For a complete depiction of forecast rainfall associated with this system, please see the National Weather Service Storm Total Rainfall Graphic, available at hurricanes.gov/graphics_at3.shtml?rainqpf and the Flash Flood Risk graphic at hurricanes.gov/graphics_at3.shtml?ero. TORNADOES: A few tornadoes may occur through this evening across eastern North Carolina. SURF: Swells are forecast to affect portions of the coast of the southeastern United States through tonight. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office.
