Remnants of Oscar Forecast Discussion Number 14

Issued at 1100 AM EDT Tue Oct 22 2024 000 WTNT41 KNHC 221455 TCDAT1 Tropical Storm Oscar Discussion Number 14 NWS National Hurricane Center Miami FL AL162024 1100 AM EDT Tue Oct 22 2024 An Air Force reconnaissance aircraft investigating Oscar has had difficulty locating a center this morning. Data from the plane and visible satellite images suggest that the circulation is becoming elongated. Also, the system may have weakened below tropical storm strength, but we will wait for an upcoming scatterometer pass that will provide a wider swath of wind data before downgrading it. Thus, for the moment, the intensity is being maintained at 35 kt. Nonetheless, since all of the stronger winds are occurring east of the center, the Tropical Storm Warning for the Central Bahamas is being discontinued. Given the poor definition of the center, the initial motion is an uncertain 040/10 kt. Oscar should accelerate northeastward along the eastern side of a mid- to upper-level trough during the next day or so. The official track forecast is a little faster than the previous NHC prediction in 24-36 hours. Within the next couple of days, the global models indicate that the trough will cause baroclinic cyclogenesis to occur near or north of Oscar. The resulting extratropical surface low is likely to absorb or merge with the tropical cyclone or its remnants. The atmospheric environment, consisting of strong shear and relatively dry air, is expected to remain hostile for the maintenance of a tropical cyclone, so no strengthening is anticipated. Indeed, it is possible that Oscar could dissipate before it interacts with the new extratropical cyclone. Key Messages: 1. Localized flash flooding will be possible today across the southeastern Bahamas and the Turks and Caicos Islands. With rainfall easing across Cuba, flooding from rainfall which has already occurred could remain a concern for the next several days. 2. Tropical storm conditions are expected in portions of the southeastern Bahamas today.

Tropical Storm Oscar Forecast Discussion Number 13

8 months 3 weeks ago
Issued at 500 AM EDT Tue Oct 22 2024 000 WTNT41 KNHC 220833 TCDAT1 Tropical Storm Oscar Discussion Number 13 NWS National Hurricane Center Miami FL AL162024 500 AM EDT Tue Oct 22 2024 Oscar is at best barely a tropical storm at this time. While convection associated with the system has increased since the last advisory, most of it is occurring in clusters well away from the center in the eastern semicircle, and there is only minimal convection near the center. Also, while 850 mb flight-level winds were as high as 45-50 kt during an earlier Air Force Reserve Hurricane Hunter mission, dropsonde and SFMR data suggests those winds were having trouble mixing down to the surface. The system will be maintained as a 35-kt tropical storm pending the next recon flight and whether convection will increase further during the upcoming diurnal maximum. The global models are in good agreement that a developing mid- to upper-level trough over the southwestern Atlantic will cause baroclinic cyclogenesis near or north of Oscar during the next 24-48 h. The UKMET shows Oscar become the main focus for the development and becoming a large extratropical low, while the GFS develops a second low to the north of Oscar with Oscar becoming absorbed into the new system. The ECMWF and Canadian models forecast a blend of these scenarios, with the baroclinic low forming close to Oscar. Given Oscar's organization and current trends in satellite imagery, the intensity forecast leans towards the GFS solution, with Oscar becoming a post-tropical low in less than 24 h and then being absorbed by the new low in 36-48 h. The initial motion is now 030/10 kt. Interaction with the above mentioned trough should steer Oscar generally northeastward with an increase in forward speed until it is absorbed by the new baroclinic low. The new forecast track is similar to the previous track. Key Messages: 1. Through Tuesday, localized flash flooding will be possible across the southeastern Bahamas as well as the Turks and Caicos Islands. With rainfall easing across Cuba, flooding from rainfall which has already occurred could remain a concern for the next several days. 2. Tropical storm conditions are expected in portions of the southeastern and central Bahamas today.
