A watch is typically issued 48 hours before the anticipated first occurrence of tropical-storm-force winds, conditions that make outside preparations difficult or dangerous. A Tropical Storm Warning means that tropical storm conditions are expected somewhere within the warning area within 36 hours. A Tropical Storm Watch means that tropical storm conditions are possible within the watch area, generally within 48 hours. For storm information specific to your area, please monitor products issued by your national meteorological service. DISCUSSION AND OUTLOOK ---------------------- At 200 AM EDT (0600 UTC), the center of Hurricane Oscar was located near latitude 21.3 North, longitude 72.6 West. Oscar is moving toward the west near 10 mph (17 km/h). A turn to the west-southwest is forecast later today, and the center of Oscar is forecast to reach the coast of Cuba tonight. A turn toward the north and northeast is expected in a couple of days. Maximum sustained winds are near 85 mph (140 km/h) with higher gusts. Small intensity fluctuations are possible during the next day or so, but weakening is anticipated tonight and Monday after the center crosses the coast. 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 is 987 mb (29.15 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 spread across portions of the warning area in the Southeastern Bahamas, particularly Great Inagua Island, this morning. Hurricane conditions are expected in the warning area in Cuba this evening. Tropical storm conditions are expected in the warning area and possible in the watch area of Cuba tonight into Monday. RAINFALL: Through Tuesday, rainfall amounts of 4 to 6 inches with isolated amounts of 8 inches are expected across eastern Cuba. Across the Turks and Caicos and southeastern Bahamas, 2 to 4 inches are expected, with isolated amounts around 6 inches. 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: A dangerous storm surge is expected to produce significant coastal flooding in the Turks and Caicos Islands and southeastern Bahamas, where water levels are expected to be between 2 and 4 feet above normal tide levels. Water levels of 1 to 3 ft above normal tide levels are expected along the north shore of Cuba in areas of onshore winds. Near the coast, the surge will be accompanied by large and destructive waves.

Issued at 1100 PM EDT Sat Oct 19 2024 000 WTNT41 KNHC 200254 TCDAT1 Hurricane Oscar Discussion Number 4 NWS National Hurricane Center Miami FL AL162024 1100 PM EDT Sat Oct 19 2024 Satellite images indicate the center of Oscar passed very near Grand Turk Island earlier this evening. Passive microwave data show the tiny hurricane has a compact inner core with a small curved band that wraps around much of its circulation. In the past several hours, the cloud pattern has become a little less symmetric, with a sharp edge to the cloud pattern on the northwest side. The conventional satellite intensity estimates remain too low relative to what the aircraft found this afternoon, and without any new observations, the initial intensity is held at 75 kt. The Air Force Hurricane Hunters are scheduled to investigate Oscar on Sunday. Oscar continues moving westward at about 10 kt, but it is forecast to turn slightly south of due west during the next day or so while moving on the southeastern side of a mid-level ridge centered over the eastern Gulf of Mexico. This should bring the center of Oscar very near or over Great Inagua in the southeastern Bahamas early Sunday, then toward the northeastern coast of Cuba through Sunday night. There has been a southward shift in the latest track guidance, with more models indicating Oscar could make landfall and move inland over eastern Cuba in 24-36 h. The latest NHC prediction has been adjusted to reflect this and lies closest to the simple consensus TVCN and GFEX aids. Thereafter, the track forecast becomes more uncertain, as the extent and duration of land interaction will dictate the depth of the vortex and how it is steered. For now, the longer-range forecast still follows the ECMWF, which shows Oscar turning northward and accelerating northeastward through midweek ahead of an amplifying upper trough. The intensity forecast for Oscar remains challenging, since its compact size makes it susceptible to more rapid intensity fluctuations. While some near-term intensification cannot be ruled out, satellite trends indicate the hurricane could be starting to feel the effects of northwesterly shear, which the global models insist will increase during the next 12-24 h. The NHC forecast still shows Oscar reaching the coast of Cuba as a hurricane on Sunday night, and the government of Cuba has issued a Hurricane Warning for a portion of the northern coast. Afterwards, land interaction and stronger shear should induce weakening, which could occur even faster than forecast if the center of the small cyclone remains inland as long as some of the guidance suggests. Key Messages: 1. A Hurricane Warning remains in effect for the Turks and Caicos and southeastern Bahamas, and a Hurricane Warning has been issued for a portion of the northern coast of Cuba. 2. Oscar is expected to produce a dangerous storm surge on portions of the Turks and Caicos Islands and the southeastern Bahamas tonight and along the north shore of Cuba later on Sunday. 3. Heavy rainfall from Oscar will lead to areas of flash flooding along with the potential of mudslides across portions of eastern Cuba, especially within the Sierra Maestra.

Therefore, the system was downgraded to a tropical depression at the intermediate advisory. Belize ground-based radar shows that Nadine has maintained a decent mid-level circulation and therefore, the initial intensity has been held at 30 kt for this advisory. Continued weakening is expected, and Nadine is forecast to dissipate over the rugged terrain of southern Mexico on Sunday. The depression is moving just south of west at 265/12 kt.
