Issued at 200 PM EDT Sat Oct 19 2024 000 WTNT41 KNHC 191755 TCDAT1 Hurricane Oscar Special Discussion Number 2 NWS National Hurricane Center Miami FL AL162024 200 PM EDT Sat Oct 19 2024 This is a special advisory to update the initial and forecast intensity for Oscar and current watches and warnings. An Air Force Reserve Hurricane Hunter mission is currently flying through the system, and in their second southwest-to-northeast leg found 700 mb flight level winds of 76 kt, and a minimum central pressure of 989 mb. The plane also reported a very small 3 n mi wide eye. A dropsonde recently launched in the northern quadrant also had a 150 m boundary layer mean wind of 80 kt. A blend of these data supports upgrading Oscar to a hurricane this advisory with maximum sustained winds of 70 kt. The intensity forecast has been updated accordingly, and is substantially higher than the previous one. Due to this unexpected higher intensity, the government of the Bahamas has issued a Hurricane Warning for the Turks and Caicos Islands and Southeastern Bahamas. The government of Cuba has also issued a Hurricane Watch for the same area currently under a Tropical Storm Warning. Key Messages: 1. Oscar is now expected to bring hurricane conditions to portions of the southeastern Bahamas, Turks and Caicos Islands, and eastern Cuba during the next day or so. A Hurricane Warning has now been issued for those locations. 2. Oscar is expected to produce a dangerous storm surge on the Turks and Caicos Islands beginning this evening. 3. Locally heavy rainfall is possible across the Turks and Caicos Islands and the southeastern Bahamas later today and tonight. These rains are expected to spread to eastern Cuba on Sunday.

DISCUSSION AND OUTLOOK ---------------------- At 200 PM EDT (1800 UTC), the center of Hurricane Oscar was located near latitude 21.4 North, longitude 70.6 West. Oscar is moving toward the west near 12 mph (19 km/h) and this motion with a gradual slowdown and turn to the west-southwest is forecast over the next couple of days. Maximum sustained winds based on aircraft data are near 80 mph (130 km/h) with higher gusts. Some additional strengthening is possible today before gradual weakening begins early next week. Hurricane-force winds extend outward up to 5 miles (10 km) from the center and tropical-storm-force winds extend outward up to 45 miles (75 km). The estimated minimum central pressure measured by dropsonde observations is 989 mb (29.21 inches). HAZARDS AFFECTING LAND ---------------------- Key messages for Oscar can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDAT1 and WMO header WTNT41 KNHC and on the web at hurricanes.gov/text/MIATCDAT1.shtml WIND: Hurricane conditions are expected to first reach the coast within the warning area tonight, with tropical storm conditions expected to begin this afternoon, making outside preparations dangerous. Tropical storm conditions are possible in the watch area on Sunday. RAINFALL: Rainfall amounts of 2 to 4 inches, with isolated amounts of 6 inches, are expected across the Turks and Caicos, southeastern Cuba, and the southeastern Bahamas through Tuesday. For a complete depiction of forecast rainfall associated with Tropical Storm Oscar, please see the National Weather Service Storm Total Rainfall Graphic, available at hurricanes.gov/graphics_at1.shtml?rainqpf . STORM SURGE: A dangerous storm surge is expected to produce significant coastal flooding in the Turks and Caicos Islands, where water levels are expected to be between 2 and 4 feet. Near the coast, the surge will be accompanied by large and destructive waves. NEXT ADVISORY ------------- Next complete advisory at 500 PM EDT. $$ Forecaster Papin/Cangialosi

Issued at 1100 AM EDT Sat Oct 19 2024 000 WTNT41 KNHC 191500 TCDAT1 Tropical Storm Oscar Discussion Number 1 NWS National Hurricane Center Miami FL AL162024 1100 AM EDT Sat Oct 19 2024 Things have been quickly evolving with a small area of low pressure located just to the east of the Turks and Caicos Islands. Earlier this morning, there was a 0556 UTC AMSR2 passive microwave image that suggested the system's structure had become quite a bit better organized compared to prior images, with prominent curved bands on the 37 GHz low-level channel that suggest a well-defined circulation was developing. While the overnight C-band scatterometer imagery missed the small circulation just to the west, there was a KU-band scatterometer that suggested a closed circulation had formed. First light GOES-16 meso-sector imagery also suggests a tight circulation has formed, with bubbling hot towers within a small central dense overcast taking shape. All these data suggest a tropical cyclone has formed, and based on the earlier 12 UTC TAFB T2.5/35 kt Dvorak estimate, advisories are being started on Tropical Storm Oscar with a 35 kt initial intensity. Oscar is estimated to be moving due westward at 270/11 kt. This motion should continue for the remainder of the day as the system is initially steered by a narrow mid-level ridge positioned to the north. However, a digging east-to-west longwave trough is soon expected to erode the eastward side of this ridge, causing Oscar to slowdown and potentially stall near the northeastern coast of Cuba in 36-48 hours. Thereafter, that same trough is expected to continue amplifying or even retrograde westward, and if Oscar is vertically deep enough, this should induce steering that brings the tropical cyclone northeastward. The track forecast lies close to the simple TCVA consensus aid, which is quite close to the most recent ECMWF forecast. Its worth mentioning, there is quite a bit of southwest-to-northeast spread in the ensemble guidance, with weaker members slower and further west and stronger members being captured by the trough. Intensity-wise, Oscar only appears to have a 24 h window for strengthening as shear remains low enough. The first NHC intensity forecast shows the system peaking as a 45-kt storm as it nears the eastern coast of Cuba. Shear out of the northwest increases quite rapidly after that time, due to the aforementioned trough to its north, with the intensity likely leveling off around then. There could also be some land interaction with Cuba that could disrupt the circulation. However Oscar is a very small tropical cyclone, and could be prone to rapid changes in intensity, both up and down. After 72 h, the much larger trough is likely to absorb the small Oscar, with this occurring by the end of the forecast period by the middle of next week. Key Messages: 1. Oscar is expected to bring tropical storm conditions to portions of the southeastern Bahamas, Turks and Caicos Islands, and eastern Cuba during the next day or so. A Tropical Storm Warning has been issued for those locations. 2. Locally heavy rainfall is possible across the Turks and Caicos Islands and the southeastern Bahamas later today and tonight. These rains are expected to spread to eastern Cuba on Sunday.

Issued at 1000 AM CDT Sat Oct 19 2024 000 WTNT45 KNHC 191457 TCDAT5 Tropical Storm Nadine Discussion Number 4 NWS National Hurricane Center Miami FL AL152024 1000 AM CDT Sat Oct 19 2024 Nadine is very close to making landfall in Belize, near Belize City. The center is currently moving across the country's barrier islands of Turneffe Atoll and landfall on the mainland will likely occur within the next hour. The sprawling tropical storm continues to slowly intensify, and a combination of objective and subjective satellite intensity estimates support increasing the maximum winds to 45 kt. Furthermore, radar data indicate that the structure of Nadine has improved and there are curved bands surrounding the center. The Air Force Hurricane Hunters are currently in the northern portion of the storm, and they will likely reach the center soon. A Tropical Cyclone Update will be provided when the storm makes landfall. The storm is moving due westward at 7 kt, and the system is expected to continue accelerating in that direction during the next day or so. This motion should take Nadine across Belize, northern Guatemala, and southern Mexico later today through Sunday. Nadine is expected to weaken after the core moves inland, and it will likely dissipate over southern Mexico by late Sunday. The remnants have a high chance of reforming in the eastern Pacific basin during the early to middle part of next week. Key Messages: 1. Localized areas of flash flooding are possible along the track of Nadine across southern Mexico, northern Guatemala, and northern Belize. 2. Tropical storm conditions are expected along portions of the coasts of Belize and the Yucatan Peninsula of Mexico within the warning area through this afternoon.
