located near latitude 23.4 North, longitude 164.7 West. Douglas is
moving toward the west-northwest near 14 mph (22 km/h). A more 
rapid motion toward the west-northwest is expected Tuesday and

Maximum sustained winds are near 60 mph (110 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 999 mb (29.50 inches).

and French Frigate Shoals overnight, bringing tropical storm
conditions. Tropical storm conditions are expected from French
Frigate Shoals to Maro Reef Tuesday and Tuesday night. Tropical
storm conditions are possible from Maro Reef to Lisianski Tuesday
night and 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. These swells will produce large breaking waves
that could inundate some of the lower-lying atolls.

the Papahanaumokuakea Marine National Monument over the next couple
of days.
