Interests in the Azores should refer to products issued by the Azores Weather Forecast and Watch Center. DISCUSSION AND 48-HOUR OUTLOOK ------------------------------ At 1100 PM AST (0300 UTC), the eye of Hurricane Ophelia was located near latitude 30.7 North, longitude 34.7 West. Ophelia is moving toward the east-northeast near 7 mph (11 km/h), and this general motion is expected to continue for the next couple of days with a large increase in forward speed. Maximum sustained winds have increased to near 105 mph (165 km/h) with higher gusts. Some slow weakening is forecast to begin Friday night but Ophelia should remain a hurricane for the next couple of days. Hurricane-force winds extend outward up to 25 miles (35 km) from the center and tropical-storm-force winds extend outward up to 90 miles (150 km). The estimated minimum central pressure is 970 mb (28.65 inches). HAZARDS AFFECTING LAND ---------------------- RAINFALL: Ophelia is expected to produce total rain accumulations of 2 to 4 inches over the southeastern Azores Saturday and 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 Blake
