Near the coast, the surge will be accompanied by large and destructive waves. RAINFALL: From Thursday into Friday morning, Gabrielle may bring 3 to 5 inches or 75 to 125 mm of rainfall across the central and western Azores. During the same time outer bands from Gabrielle may also result in 1 to 2 inches or 25 to 50 mm of rain across the eastern Azores. SURF: Swells generated by Gabrielle will continue to affect Bermuda, the U.S. East Coast from North Carolina northward, and Atlantic Canada over the next few days. These swells are expected to produce life-threatening surf and rip current conditions. Please consult products issued by your local weather office.
