Hurricane Ophelia Discussion Number 22NWS National Hurricane Center Miami FL AL1720171100 AM AST Sat Oct 14 2017During the past few hours, Ophelia's satellite presentation hasimproved significantly. The eye has become even more distinctwith a temperature of 16 deg C, and has been surrounded by verydeep convection. T-numbers from TAFB and SAB have reached 5.5 on theDvorak scale, and the objective numbers from CIMMS have beenoscillating around T5.8 and T5.9 recently. Based on these estimates,the initial intensity has been increased conservatively to 100 kt,making Ophelia a category 3 hurricane on the SSHS. Ophelia is aquite intense and rare hurricane for its location in thenortheastern Atlantic. Increasing shear and cold waters willsoon begin to impact Ophelia, and the hurricane should begin toacquire extratropical characteristics in about 36 hours or sooner.Although some weakening is anticipated, Ophelia is expected to reachthe British Isles as a powerful extratropical cyclone with hurricaneforce winds. Dissipation is forecast in about 4 days after thesystem moved over these Isles.Satellite fixes indicate that Ophelia is moving toward the northeastor 055 degrees at 22 kt. The hurricane is well embedded within thesouthwesterly flow associated with the southern extension of a largemid-latitude trough, and this pattern should continue to steer thecyclone northeastward and north-northeastward with increasingforward speed for the next 2 to 3 days until dissipation. Trackmodels are in excellent agreement and the guidance envelope is quitetight. The NHC forecast is not different from previous ones, and itis very close to the HFIP corrected consensus HCCA and themulti-model ensemble TVCX.Given that Ophelia is forecast to become extratropical, the windfield should expand, resulting in impacts over portions of theBritish Isles regardless of its exact location or strength.Although the center of Ophelia is not forecast to reach Ireland orthe UK for another couple of days, wind and rains will arrivewell in advance of the cyclone center. Individuals in thoselocations should consult products from their local meteorologicalservice for more information on local impacts.Tropical-storm-force winds are possible throughout the Azoresafter Ophelia passes to the south and east later today and tonightas a cold front moves through the islands. Interests in the Azoresshould refer to products issued by the Azores Weather Forecast andWatch Center.KEY MESSAGES:1. Ophelia is expected to be a powerful extratropical cyclone withhurricane force winds Monday while it moves near Ireland and theUnited Kingdom. Direct impacts from wind and heavy rain in portionsof these areas are likely, along with dangerous marine conditions.For more details on the magnitude, timing, and location of impactsfrom post-tropical Ophelia, residents in Ireland should refer toproducts issued by Met Eireann, and residents in the United Kingdomshould refer to products issued by the Met Office.FORECAST POSITIONS AND MAX WINDSINIT 14/1500Z 34.8N 26.6W 100 KT 115 MPH 12H 15/0000Z 36.5N 23.0W 95 KT 110 MPH 24H 15/1200Z 40.5N 18.0W 90 KT 105 MPH 36H 16/0000Z 46.5N 14.0W 85 KT 100 MPH...POST-TROP/EXTRATROP 48H 16/1200Z 51.5N 11.0W 75 KT 85 MPH...POST-TROP/EXTRATROP 72H 17/1200Z 59.0N 6.0W 40 KT 45 MPH...POST-TROP/EXTRATROP 96H 18/1200Z...DISSIPATED
¿podría cambiar la situación en la península a raíz de la intensificación de ophelia a huracán cat3?
