Post-Tropical Cyclone Ophelia Discussion Number 28
NWS National Hurricane Center Miami FL AL172017
1100 PM AST Sun Oct 15 2017
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 kt to the east
of the center. Based on these data, the initial intensity remains
75 kt 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.
