A turn toward the northeast is expected on Sunday. On the forecast track, the core of Ophelia will pass south of the southeastern Azores by late Saturday or early Sunday. Maximum sustained winds remain near 100 mph (155 km/h) with higher gusts. Ophelia is expected to remain a powerful cyclone for the next couple of days.

The estimated minimum central pressure is 971 mb (28.68 inches).

RAINFALL: Ophelia is expected to produce total rain accumulations of 2 to 4 inches over the southeastern Azores through Saturday night. During the same time, a cold front and moisture associated with Ophelia is expected to produce total rain accumulations of 1 to 3 inches over the other islands of the Azores. This rainfall could produce flooding, especially over the southeastern Azores. NEXT ADVISORY ------------- Next complete advisory at 500 AM AST. $$ Forecaster Avila |
