WATCHES AND WARNINGS
Flash Flood Watches are in effect along the central Gulf Coast from portions of southeast Louisiana, across southern Mississippi and Alabama, to the Florida Panhandle.
At 10:00 AM CDT (15h00 UTC), the center of Post-Tropical Nicholas was located near latitude 29.8 North, longitude 91.7 West. The circulation associated with Nicholas was moving slowly to the north around 2 mph (4 km/h) and this motion is expected to continue through Friday. The heaviest rainfall associated with the post-tropical low will continue to be well removed to the east of the circulation today. However, there is some chance for thunderstorm development closer to the cyclone center, and these thunderstorms could pose a risk of locally heavy rainfall, while additional thunderstorms continue to move northeast from the Gulf of Mexico across southeast Louisiana, southern Mississippi and Alabama, to the Florida Panhandle.
Maximum sustained winds are near 25 mph (35 km/h) with higher gusts. The system is forecast to remain relatively weak through 48 hours.
1- Showers and Thunderstorms (70%)
Showers and thunderstorms have become slightly less organized in association with a tropical wave located a little more than 800 miles west-southwest of the Cabo Verde Islands. However, environmental conditions are expected to be conducive for development during the next few days, and a tropical depression is still likely to form late this week or this weekend. This system is expected to move westward to west-northwestward across the tropical Atlantic during the next several days.
* Formation chance through 48 hours, high, 70 percent.
* Formation chance through 5 days, high, 80 percent.
2- Showers and Thunderstorms (70%)
Shower and thunderstorm activity has increased this morning over the eastern portion of a broad area of low pressure located about 250 miles south-southeast of the Outer Banks of North Carolina. Environmental conditions are expected to become more conducive for development, and a tropical depression is still likely to form during the next day or two while the system moves northward to north-northeastward off the southeast and mid-Atlantic U.S. coasts. Regardless of development, this system could bring high surf to portions of the southeast and mid-Atlantic U.S. coasts later this week and this weekend. Additional information on this system, including gale warnings, can be found in High Seas Forecasts issued by the NOAA Ocean Prediction Center. An Air Force Reserve reconnaissance aircraft is scheduled to investigate the disturbance this afternoon.
- Formation chance through 48 hours, high, 70 percent
- Formation chance through 5 days, high, 70 percent
3- Showers and Thunderstorms (10%)
Showers and thunderstorms over the far eastern tropical Atlantic are associated with a tropical wave that will move off the west coast of Africa today. Environmental conditions are forecast to be marginally conducive for some gradual development over the next few days while the system moves west-northwestward to northwestward over the far eastern Atlantic.
- Formation chance through 48 hours, low, 10 percent
- Formation chance through 5 days, low, 20 percent
