Douglas is moving toward the west-northwest near 18 mph (30 km/h), and this motion is expected to continue for the next few days with a gradual decrease in forward speed and a slight turn toward the west. On the forecast track Douglas will approach the Hawaiian Islands Saturday night, and be near those Islands on Sunday. Maximum sustained winds have increased to near 130 mph (215 km/h) with higher gusts. Douglas is a category 4 hurricane on the Saffir-Simpson Hurricane Wind Scale.

The estimated minimum central pressure is 954 mb (28.17 inches).

A watch is typically issued 48 hours before the anticipated first occurrence of tropical-storm-force winds, conditions that make outside preparations difficult or dangerous. A Tropical Storm Watch means that tropical storm conditions are possible within the watch area, generally within 48 hours. Interests elsewhere in the Windward Islands should monitor the progress of this system. Additional watches or warnings will likely be required for some of these islands tonight or on Friday. For storm information specific to your area, please monitor products issued by your national meteorological service. DISCUSSION AND OUTLOOK ---------------------- At 1100 PM AST (0300 UTC), the center of Tropical Storm Gonzalo was located near latitude 9.9 North, longitude 50.6 West.

On the forecast track, the center of Gonzalo will approach the southern Windward Islands Friday night and move across the islands Saturday and into the eastern Caribbean Sea Sunday. Maximum sustained winds are near 60 mph (95 km/h) with higher gusts. Some strengthening is forecast during the next day or two, and there is still a chance that Gonzalo could become a hurricane. Weakening is expected after Gonzalo moves into the Caribbean Sea and the cyclone is expected to dissipate by the middle of next week. Tropical-storm-force winds extend outward up to 25 miles (35 km) from the center. The estimated minimum central pressure is 1000 mb (29.53 inches). HAZARDS AFFECTING LAND ---------------------- Key messages for Gonzalo can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDAT2 and WMO header WTNT42 KNHC.
