Maximum sustained winds are near 50 mph (85 km/h) with higher gusts. Weakening is forecast over the next couple of days, and Douglas is expected to dissipate by Thursday. Tropical-storm-force winds extend outward up to 125 miles (205 km) from the center. The estimated minimum central pressure is 1001 mb (29.56 inches).

Tropical storm conditions are possible from Maro Reef to Lisianski later tonight into Wednesday. SURF: Large seas and swells generated by Douglas will impact a large swath of the Papahanaumokuakea Marine National Monument the next day or two.
