DISCUSSION AND OUTLOOK
At 500 PM AST (2100 UTC), the center of Tropical Storm Sebastien was
located near latitude 39.2 North, longitude 32.5 West. Sebastien is
moving toward the east-northeast near 39 mph (63 km/h). An even
faster motion toward the northeast or east-northeast is expected
during the next day or so. On the forecast track, the center of
Sebastien will pass near the western Azores tonight.
Maximum sustained winds are near 65 mph (100 km/h) with higher
gusts. A slow decrease in the maximum winds is expected during the
next day or so. Sebastien is forecast to become post-tropical
by early Monday, and it could degenerate into a trough of low
pressure at any time during the next couple of days. Regardless of
status, Sebastien or its remnants will likely continue to produce
tropical-storm-force winds for at least a couple more days.
Tropical-storm-force winds extend outward up to 140 miles (220 km)
from the center.
The estimated minimum central pressure is 994 mb (29.36 inches).
HAZARDS AFFECTING LAND
WIND AND RAIN: Sebastien or its remnants are expected to bring
gusty winds and rain to the Azores through Monday morning. Please
see products issued by the Portuguese Institute for the Sea and the
Atmosphere (IPMA) for more information.
SURF: Swells generated by Sebastien are expected to affect the
Azores during the next couple of days. These swells are likely to
cause life-threatening surf and rip current conditions.
Hurricane Michael is centered as of 4 a.m. CDT over the southern Gulf of Mexico about 390 miles (630 km) south of Apalachicola. On the forecast track, the center will continue to move over the southern Gulf of Mexico this morning, then move across the eastern Gulf of Mexico later today and tonight, move inland over the Florida Panhandle or Florida Big Bend area on Wednesday, and then move northeastward across the southeastern United States Wednesday night and Thursday.
Maximum sustained winds are near 90 mph (150 km/h) with higher gusts. Strengthening is expected, and Michael is forecast to be a major hurricane at landfall in Florida. Weakening is expected after landfall as Michael moves through the southeastern United States.
A Storm Surge Warning is in effect from the Okaloosa County Line Florida to Anclote River Florida. A Storm Surge Watch is in effect from the Anclote River to Anna Maria Island Florida, including Tampa Bay, and from the Alabama/Florida border to Okaloosa/Walton County Line, Florida. A Hurricane Warning is in effect from the Alabama/Florida border to Suwannee River Florida. A Hurricane Watch is in effect from the Alabama/Florida border to the Mississippi/Alabama border.

An intermediate advisory will be issued by NHC at 7 a.m. CDT and a complete advisory at 10 a.m. CDT – www.hurricanes.gov
NHC has begun issuing advisories on Potential Tropical Cyclone Eighteen. It’s located over the Northwest Caribbean Sea about 305 miles (490 km) south-southwest of the Isle of Youth and about 415 miles (670 km) south-southwest of Havana, Cuba.
A Tropical Storm Warning is in effect for Isla de la Juventud, La Habana, Ciudad de la Habana, Matanzas, Cienfuegos, and Villa Clara, and the Northwestern Bahamas. A Tropical Storm Watch is in effect for the Central Bahamas. Tropical storm conditions are expected to first reach the warning area in Cuba Saturday and the northwestern Bahamas Saturday night. Interests in the Cayman Islands, South Florida, and the Florida Keys should monitor the progress of this system.
On the forecast track, the system will move across western Cuba late Saturday and move through then northwestern Bahamas Saturday night and early Sunday. Data from an Air Force Reserve Hurricane Hunter aircraft indicate that maximum sustained winds are near 40 mph (65 km/h) with higher gusts. However, the system does not yet have a well-defined center. Some strengthening is forecast during the next 24 to 36 hours. Environmental conditions are expected to be conducive for development, and the system is likely to become a tropical storm tonight or Saturday. When that occurs, it will be given the name “Philippe”.
The system has the potential to produce the following rainfall totals:
– Northern Honduras: Additional 1 to 3 inches tonight.
– Cayman Islands, western and central Cuba and the Northwest
Bahamas: 4 to 8 inches with maximum totals of 10 inches.
These rainfall amounts may produce life threatening flash floods and mudslides.
– South Florida, including the Florida Keys: 3 to 5 inches, with isolated maximum of 8 inches possible. These rainfall totals may produce flash flooding, especially in urbanized areas.
Hurricane Otto made landfall in southern Nicaragua on Thursday, Nov. 24 with maximum sustained winds near 110 mph (175 kph) as a strong Category 2 hurricane on the Saffir-Simpson Hurricane Wind Scale. A NASA animation of NOAA’s GOES satellite imagery captured the movement and landfall of this late-season storm.
At 1 p.m. EST on Nov. 24 the eye of dangerous hurricane Otto made landfall on the southern Nicaraguan coast near the town of San Juan De Nicaragu, which is about 70 miles (110 km) south of Bluefields, Nicaragua.
An animation of visible and infrared imagery from NOAA’s GOES-East satellite over the period of Nov. 22 to Nov. 25 showed Hurricane Otto moving through the southwestern Caribbean Sea and make landfall in southern Nicaragua on Nov. 24. The GOES series of satellites are managed by NOAA, and the NASA/NOAA GOES Project at NASA’s Goddard Space Flight Center in Greenbelt, Maryland uses that data to create images and animations.
On Nov. 25 at 7 a.m. EST (1200 UTC) Otto’s center had exited Nicaragua and moved into the Eastern Pacific Ocean. The National Hurricane Center (NHC) said that all warnings and watches have been discontinued.
The center of Tropical Storm Otto was located near latitude 10.5 North and longitude 87.6 West. That puts the center of Otto about 115 miles (190 km) west-southwest of Santa Elena, Costa Rica. Otto was moving toward the west near 14 mph (22 kph). NHC expects a westward motion on Saturday, Nov. 26. Maximum sustained winds are near 60 mph (95 kph) with higher gusts. Little change in strength is forecast during the next 48 hours.
An infrared image from NOAA’s GOES-West satellite on Nov. 25 at 8:30 a.m. EST (1330 UTC) showed Tropical Storm Otto in the Eastern Pacific Ocean

At least four people have died in Panama in severe weather caused by the approach of Tropical Storm Otto, officials say. Two victims died in a mudslide, a girl drowned in a river and a boy died when a tree fell on the car taking him to school. His mother, driving, survived.
The Panamanian education minister has suspended classes until Thursday.
Tropical Storm Otto is stationary as of late Tuesday morning, centered about 330 miles (530 km) east-southeast of Bluefields, Nicaragua. A westward drift is expected to begin later today, followed by a faster westward motion on Wednesday. On the forecast track, Otto should be approaching the coasts of Nicaragua and Costa Rica on Thursday.
Maximum sustained winds are near 70 mph (110 km/h) with higher gusts. Otto is expected to become a hurricane later today or tonight, with additional strengthening forecast through Thursday.
A Hurricane Watch is in effect from the Costa Rica/Panama border to south of Bluefields, aTropical Storm Warning is in effect from Nargana to Colon, a Tropical Storm Watch is in effect for San Andresa and from west of Colon to the Costa Rica/Panama border.
Tropical storm conditions are expected within the warning area today and tonight. Tropical storm conditions are possible within the tropical storm watch area on Wednesday or Wednesday night. Hurricane conditions are possible within the hurricane watch area on Thursday.
Outer rain bands from Otto are expected to produce rainfall accumulations of 3 to 6 inches over San Andres and Providencia islands, and the higher terrain of central and western Panama and southern Costa Rica through Wednesday. Total rainfall of 6 to 12 inches, with isolated amounts of 15 to 20 inches, can be expected across northern Costa Rica and southern Nicaragua through Thursday.
