Tropical Cyclone Odette
TROPICAL STORM ODETTE FORMS OFF THE U.S. MID-ATLANTIC COAST…FORECAST TO BECOME POST-TROPICAL BY SATURDAY NIGHT SOUTH OF ATLANTIC CANADA
According to the NHC Advisory 1…Odette is moving toward the northeast near 15 mph (24 km/h), and this general motion is expected to continue into tonight. A turn toward the east-northeast with an increase in forward speed is expected to begin on Saturday and continue through Monday.
On the forecast track, the center of Odette will move away from the U.S. Mid-Atlantic coast and pass south of Atlantic Canada over the weekend. Maximum sustained winds are near 40 mph (65 km/h) with higher gusts.
Strengthening is forecast during the next couple of days, and Odette is expected to become a strong post-tropical low by Saturday night.
Tropical-storm-force winds extend outward up to 115 miles (185 km) to the north of the center.
Showers and thunderstorms associated with a tropical wave and broad area of low pressure located about midway between the Lesser Antilles and the Cabo Verde Islands have become a little better organized since yesterday. Environmental conditions are expected to be conducive for further development during the next couple of days, and a tropical depression is likely to form over the weekend or early next week while moving toward the west-northwest at about 15 mph across the central tropical Atlantic and then near the northern Leeward Islands by Monday and Tuesday. Upper-level winds could become less conducive for development over the southwestern Atlantic by the early to middle part of next week. Interests in the Leeward Islands should monitor the progress of this system during the next few days.
* Formation chance through 48 hours…high…80 percent
* Formation chance through 5 days…high…80 percent
>>> A broad area of low pressure located a few hundred miles south-southeast of the Cabo Verde Islands continues to produce disorganized showers and thunderstorms.
This system is expected to move toward the west and then northwest at 5 to 10 mph over the far eastern Atlantic, and some gradual development is possible over the weekend before upper-level winds increase and the low moves over cooler waters.
* Formation chance through 48 hours…low…20 percent
* Formation chance through 5 days…low…30 percent

Post-Tropical Cyclone Nicholas
POST-TROPICAL CYCLONE NICHOLAS CONTINUES TO DECAY/WEAKEN OVER NORTHERN LOUISIANA…FLASH FLOODING REMAINS POSSIBLE ACROSS PORTIONS OF THE CENTRAL GULF COAST
According to the NHC Advisory 23…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.
HAZARDS AFFECTING LAND
RAINFALL: Nicholas is expected to produce additional rainfall of 1 to 2 inches across the central Gulf coast through the end of the week, with isolated storm total amounts of 14 inches possible. 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, southern Mississippi, southern Alabama, and the Florida Panhandle.
