Hurricane Ophelia 2017

Last Modified:

Satellite images and tracking maps of Category 3 Major Hurricane Ophelia 2017, October 6 - 17. Max wind speed 115mph.

Ophelia will remain a powerful extratropical cyclone with hurricane-force winds while it moves near Ireland and the United Kingdom Monday and Monday night. Strong winds and heavy rain are likely in portions of these areas, along with dangerous marine conditions. For more details on the magnitude, timing, and location of impacts from post-tropical Ophelia, residents in Ireland should refer to products issued by Met Eireann, and residents in the United Kingdom should refer to products issued by the Met Office.

Individuals are urged to not focus on the exact track of Ophelia since strong winds and heavy rainfall will extend well outside of the NHC forecast cone.

Within just the past six hours, the last bit of deep convection near Ophelia's center has been sheared off well to the north, and the cyclone has acquired a definitive extratropical structure. Ophelia has completed its transition to an occluded low, with an attached warm front extending northeastward across Ireland and a cold front draped southeastward toward Spain and Portugal. The powerful cyclone continues to produce hurricane-force winds, with recent ASCAT data showing wind vectors as high as 70 knots to the east of the center. Based on these data, the initial intensity remains 75 knots to account for undersampling. The occluded low is forecast to gradually fill and weaken during the next couple of days, and it is likely to dissipate near the western coast of Norway by 48 hours. Despite the expected weakening, the post-tropical cyclone is still likely to bring hurricane-force winds, especially in gusts, to portions of western Ireland on Monday.

Ophelia has accelerated and retrograded slightly during the past 6-12 hours during the occlusion process, and the long-term motion estimate is northward, or 010/38 knots. Now that occlusion is complete, the post-tropical cyclone should resume a north-northeastward motion, with some decrease in forward speed, within the next 12 hours. That heading should continue for the ensuing day or two, bringing the center of the cyclone near the western coast of Ireland on Monday and then near northern Scotland Monday night. The dynamical track models remain in good agreement on this scenario, and the updated NHC forecast is not too different from the previous one.

This is the last advisory issued by the National Hurricane Center now that Ophelia has become post-tropical. Local forecasts, warnings, and other communications regarding the post-tropical cyclone that are pertinent to Ireland and the United Kingdom will continue to be available from Met Eireann and the UK Met Office.
