Hazards affecting land

Wind. Tropical storm conditions, with gusts to hurricane force, are occurring in the central Azores and will spread to the southeastern Azores over the next couple of hours. Strong, gusty winds will continue across these islands through the morning.

Gusty winds are possible along portions of the coast of Portugal late Saturday through Sunday.

Storm surge. A dangerous storm surge is expected to produce significant coastal flooding in areas of onshore winds in the Azores. The surge will be accompanied by large and destructive waves.

Rainfall. Through this morning, Gabrielle could produce 3 to 5 inches, or 75 to 125 mm, of storm total rainfall across the central Azores. This rainfall could cause flash flooding across the terrain. Elsewhere, Gabrielle is expected to produce 1 to 3 inches, or 25 to 75 mm, of rain across the eastern Azores.

Surf. Swells generated by Gabrielle will affect the Azores through the weekend and will reach the coasts of Portugal, northwestern Spain, and northern Morocco on Saturday. These swells are expected to produce life-threatening surf and rip current conditions.
