Douglas is moving toward the west-northwest near 18 mph (30 km/h). This motion is expected to continue with a slight decrease in forward speed today, followed by a slight turn toward the west tonight through Monday. On the forecast track, Douglas will be near the main Hawaiian Islands late tonight through Sunday night.

Maximum sustained winds are near 100 mph (160 km/h) with higher gusts. Gradual weakening is expected through the weekend. However, Douglas is still forecast to be near hurricane strength when it nears the islands.

Hurricane-force winds extend outward up to 25 miles (35 km) from the center and tropical-storm-force winds extend outward up to 105 miles (165 km). The estimated minimum central pressure is 982 mb (29.00 inches).

HAZARDS AFFECTING LAND

WIND: Hurricane conditions are possible across portions of the main Hawaiian Islands late tonight through Sunday night. Tropical Storm conditions are expected across Hawaii County and Maui County beginning late tonight or Sunday. Tropical Storm conditions are possible across Kauai County late Sunday or Sunday night.

SURF: Large swells generated by Douglas are expected to affect the Hawaiian Islands this weekend, and storm surge of around 2 feet above normal tides is expected near the center of Douglas. The large swells and surge will produce life-threatening and potentially damaging surf along exposed shores.

RAINFALL: Heavy rainfall associated with Douglas is expected to affect portions of the main Hawaiian Islands from late tonight through Monday. Total rain accumulations of five to 10 inches are possible from Maui County westward to Kauai County, with the greatest amounts in elevated terrain. This rain may resulting life-threatening flash flooding and landslides, as well as rapid water level rises on small streams. Douglas is expected to produce two to five inches of rainfall over the northern half of the Big Island.
