000 WTNT34 KWNH 172058 TCPAT4 BULLETIN Post-Tropical Cyclone Nicholas Advisory Number 23 NWS Weather Prediction Center College Park MD AL142021 400 PM CDT Fri Sep 17 2021 ...POST-TROPICAL CYCLONE NICHOLAS CONTINUES TO DECAY/WEAKEN OVER NORTHERN LOUISIANA... ...FLASH FLOODING REMAINS POSSIBLE ACROSS PORTIONS OF THE CENTRAL GULF COAST... SUMMARY OF 400 PM CDT...2100 UTC...INFORMATION ---------------------------------------------- LOCATION...32.0N 92.7W ABOUT 70 MI...110 KM ESE OF SHREVEPORT LOUISIANA MAXIMUM SUSTAINED WINDS...15 MPH...30 KM/H PRESENT MOVEMENT...N OR 360 DEGREES AT 2 MPH...4 KM/H MINIMUM CENTRAL PRESSURE...1014 MB...29.95 INCHES WATCHES AND WARNINGS -------------------- Flash Flood Watches are in effect along sections of the central Gulf Coast from southeast Louisiana across southern Mississippi and southern Alabama into the Florida Panhandle. DISCUSSION AND OUTLOOK ---------------------- At 400 PM CDT (2100 UTC), the center of Post-Tropical Cyclone Nicholas was located near latitude 32.0 North, longitude 92.7 West. The post-tropical cyclone is moving toward the north near 2 mph (4 km/h). The center of Nicholas continues to gradually decay and will become increasingly ill-defined in the surface pattern over the next 24 hours. While daytime heating has contributed to some renewed scattered showers and thunderstorms near and around the center of Nicholas, the larger and more persistent band of heavy rain continues to move across the central Gulf Coast, and is well removed from the weakening post-tropical cyclone. Given the separation of this heavy rainfall from Nicholas's remnant circulation, this will be the last WPC Advisory for Nicholas. Maximum sustained winds are near 15 mph (30 km/h) with higher gusts possible in showers and thunderstorms. Again, the circulation is expected to continue to weaken over northern Louisiana or northeast Texas over the next 24 hours. The estimated minimum central pressure is 1014 mb (29.95 inches). HAZARDS AFFECTING LAND ---------------------- RAINFALL: The band of heavier and steadier rainfall, well removed from the circulation of Nicholas, is expected to produce additional rainfall of 1 to 3 inches across the central Gulf coast through Saturday, with localized amounts of 6 inches possible. Within this region, isolated storm total rainfall amounts may reach 14 inches. Flash flooding impacts, especially in urban areas, are possible across these regions. Widespread minor to scattered moderate river flooding is ongoing or forecast across portions of southeastern Louisiana and southern Mississippi.
