Large swells generated by Douglas are expected to affect the Hawaiian Islands during the next couple of days, and a storm surge of 2 to 4 feet above normal tides is expected near the center of Douglas. The large swells and surge will produce life-threatening and potentially destructive surf along exposed shores.
At 11 a.m. HST, the center of Hurricane Douglas was located about 325 miles (525 miles) east of Hilo, Hawaii. It’s moving toward the west-northwest near 18 mph (30 km/h). This motion is expected to continue through the next couple of days, with a slight decrease in forward speed today. On the forecast track, Douglas will be near the main Hawaiian Islands late tonight and will move over parts of the state Sunday and Monday.
Maximum sustained winds are near 90 mph (150 km/h) with higher gusts. Hurricane-force winds extend outward up to 30 miles (45 km) from the center and tropical-storm-force winds extend outward up to 110 miles (175 km). Gradual weakening is expected through the weekend. However, Douglas is still forecast to be near hurricane strength when it nears the islands.
Heavy rainfall associated with Douglas is expected to affect portions of the main Hawaiian Islands from late tonight through Monday. Total rain accumulations of 5 to 10 inches are possible from Maui County westward to Kauai County, with the greatest amounts in elevated terrain. This rain may result in life-threatening flash flooding and landslides, as well as rapid water level rises on small streams. Douglas is expected to produce 2 to 5 inches of rainfall over the northern half of the Big Island.
