SUMMARY OF WATCHES AND WARNINGS IN EFFECT: A Tropical Storm Warning is in effect for... * North coast of the Cuban Provinces of Las Tunas, Holguin, and Guantanamo to Punta Maisi * South coast of Cuban Province of Guantanamo * Central Bahamas * Southeastern Bahamas A Tropical Storm Warning means that tropical storm conditions are expected somewhere within the warning area. For storm information specific to your area, please monitor products issued by your national meteorological service. DISCUSSION AND OUTLOOK ---------------------- At 800 PM EDT (0000 UTC), the center of Tropical Storm Oscar was located near latitude 21.4 North, longitude 75.7 West. Oscar is moving toward the north-northeast near 7 mph (11 km/h). A faster northeastward motion is expected on Tuesday and Wednesday. On the forecast track, the center of Oscar is expected to move near the southeastern and central Bahamas on Tuesday. Maximum sustained winds are near 40 mph (65 km/h) with higher gusts. Some slight strengthening is possible during the next day or so. Tropical-storm-force winds extend outward up to 90 miles (150 km) southeast and northeast of the center. The estimated minimum central pressure is 1005 mb (29.68 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: Tropical storm conditions, mainly in gusts, are expected within the warning area in eastern Cuba for the next few hours. Tropical storm conditions are expected in the warning area in parts of the central and southeastern Bahamas tonight and Tuesday. RAINFALL: Through Wednesday morning, rainfall amounts of 7 to 14 inches with isolated amounts of 20 inches are expected across eastern Cuba, especially within the Sierra Maestra. This rainfall will lead to areas of significant, life-threatening flash flooding along with mudslides. Preliminary reports indicate there have already been over 10 inches of rain in spots in the Province of Guantanamo. Across the southeastern Bahamas, 3 to 5 inches are expected, with isolated amounts around 8 inches. This rainfall could cause localized flash flooding. For a complete depiction of forecast rainfall associated with Oscar, please see the National Weather Service Storm Total Rainfall Graphic, available at hurricanes.gov/graphics_at1.shtml?rainqpf STORM SURGE: Elevated water levels in areas of onshore winds along the coast of eastern Cuba will gradually subside tonight. Near the coast, large and dangerous waves will continue into early Tuesday. NEXT ADVISORY ------------- Next complete advisory at 1100 PM EDT. $$ Forecaster Reinhart

Issued at 500 PM EDT Mon Oct 21 2024 000 WTNT41 KNHC 212042 TCDAT1 Tropical Storm Oscar Discussion Number 11 NWS National Hurricane Center Miami FL AL162024 500 PM EDT Mon Oct 21 2024 Although the circulation of Oscar is rather broad, visible satellite images show that the center is nearing the northern coast of eastern Cuba. Deep convection associated with the system has diminished during the day, at least partially due to a diurnal fluctuation. The intensity is kept, perhaps generously, at 35 kt for this advisory. Surface synoptic observations and earlier scatterometer data indicate that the strongest winds are over the eastern semicircle of the cyclone, and no tropical-storm-force wind radii are shown to the northwest or southwest of the center for this advisory. Oscar been turning fairly sharply to the right while the system executes a hairpin turn over eastern Cuba. The current motion estimate is around 330/6 kt. The tropical cyclone is expected to turn northward and northeastward with some increase in forward speed while it moves on the southeastern and eastern side of a mid-level trough. Since the system has moved a little farther west than previously estimated, the overall official track forecast has been shifted slightly west of the previous one. This is a blend of the simple and corrected dynamical model consensus predictions. The tropical cyclone should move back over water soon, so some restrengthening is possible during the next day or two. However, Oscar will be moving into an area of strong upper-level winds over the next couple of days which should impart significant westerly shear over the system. Also, the cyclone is expected to remain in a relatively dry air mass to the north of the Greater Antilles. Thus, only slight restrengthening seems possible. The official intensity forecast is above the latest SHIPS and LGEM guidance. In 2 to 3 days, the global models show the system being absorbed by a non-tropical low pressure system to the west of Bermuda. The primary hazard associated with Oscar will continue to be heavy rainfall and life-threatening flash flooding, particularly over the mountainous terrain of eastern Cuba. Over the last 24 hours, a rainfall total of nearly 15 inches was reported at Punta de Maisi on the eastern tip of Cuba. Key Messages: 1. Through midweek, heavy rainfall from Oscar will lead to areas of significant, life-threatening flash flooding along with mudslides across portions of eastern Cuba, especially within the Sierra Maestra. In addition, localized flash flooding will be possible across the southeastern Bahamas. 2. Tropical storm conditions are expected to continue into this evening across portions of eastern Cuba. Tropical storm conditions are also expected in portions of the southeastern and central Bahamas tonight and Tuesday.

Maximum sustained winds are near 40 mph (65 km/h) with higher gusts. Some additional weakening is possible while the center remains over land today, followed by slight restrengthening after the center moves back over water and near the southeastern and central Bahamas on Tuesday. Tropical-storm-force winds extend outward up to 90 miles (150 km) from the center. An ASOS weather station in Guantanamo Bay, Cuba recently reported a wind gust of 45 mph (72 km/h).

Issued at 1100 AM EDT Mon Oct 21 2024 322 WTNT41 KNHC 211445 TCDAT1 Tropical Storm Oscar Discussion Number 10 NWS National Hurricane Center Miami FL AL162024 1100 AM EDT Mon Oct 21 2024 Surface observations and visible satellite imagery indicate that the center of Oscar, although not very easy to locate, is still moving over eastern Cuba this morning. Radar observations from Guantanamo Bay show that the inner core of the tropical cyclone has become severely disrupted. The system has continued to weaken while interacting with the very mountainous terrain, and the initial wind speed is estimated to have decreased to near 35 kt, although this may be generous. The initial motion is an uncertain 300/3 kt. It is possible that the center of the system may re-form near the northern coast of Cuba later today. In any event, Oscar is expected to turn northward and northeastward on the eastern side of a mid-level trough over the western Bahamas through tonight. The system should then accelerate northeastward over portions of the southeastern Bahamas and western Atlantic ahead of the aforementioned trough. Global model predictions show the circulation of Oscar becoming absorbed by a larger, developing non-tropical low pressure area to the west of Bermuda by day 3. The NHC track forecast is similar to the previous one and is very close to the dynamical model consensus. Some additional weakening is expected while Oscar continues to interact with the land mass of eastern Cuba today, and Oscar could weaken to a tropical depression before the circulation moves over water. Thereafter, the system will be contending with increasing westerly vertical wind shear and drier air. Therefore only slight restrengthening is anticipated within the next day or so, followed by little change in strength before Oscar becomes absorbed by the non-tropical low pressure system. The primary hazard associated with Oscar will continue to be heavy rainfall and life-threatening flash flooding, particularly over the mountainous terrain of eastern Cuba. Preliminary reports in the Province of Guantanamo in eastern Cuba already indicate more than 10 inches of rain have fallen in spots. Key Messages: 1. Through midweek, heavy rainfall from Oscar will lead to areas of significant, life-threatening flash flooding along with mudslides across portions of eastern Cuba, especially within the Sierra Maestra. In addition, localized flash flooding will be possible across the southeastern Bahamas. 2. Tropical storm conditions are expected to continue today across portions of eastern Cuba. Tropical storm conditions are also expected in portions of the southeastern Bahamas tonight and Tuesday.
