DISCUSSION AND OUTLOOK ---------------------- At 200 AM AST (0600 UTC), the center of Tropical Storm Ernesto was located by San Juan radar near latitude 19.0 North, longitude 66.0 West. Ernesto is moving toward the northwest near 16 mph (25 km/h). A turn toward the north-northwest and north with a gradual decrease in forward speed is expected tonight and Thursday. On the forecast track, the center of Ernesto will pass to the north of Puerto Rico through today. Ernesto should then move over the western Atlantic later in the week and approach Bermuda on Friday and Friday night. Surface observations indicate that the maximum sustained winds have increased to near 70 mph (110 km/h) with higher gusts. Strengthening is forecast during the next several days, and Ernesto is expected to become a hurricane later this morning and could become a major hurricane in a couple of days. Tropical-storm-force winds extend outward up to 125 miles (205 km) from the center. A WeatherFlow station (XCUL) on Culebra recently reported a sustained wind of 68 mph (109 km/h) and a gust of 86 mph (139 km/h). A NOAA Saildrone located about 70 miles north- northeast of San Juan, Puerto Rico, recently reported a sustained wind of 52 mph (84 km/h) with a gust to 63 mph (101 km/h). The estimated minimum central pressure is 996 mb (29.41 inches).

RAINFALL: Ernesto is expected to produce total rain accumulations of 4 to 6 inches over the U.S and British Virgin Islands. Rainfall totals of 6 to 8 inches, with maximum amounts of 10 inches, are expected across southeastern Puerto Rico, with totals of 2 to 4 inches across northwestern Puerto Rico.

Hurricane conditions are possible in portions of the watch area during the next few hours. STORM SURGE: A storm surge will raise water levels by as much as 1 to 3 feet above ground level for the eastern coast of Puerto Rico from San Juan to Guayama, including the islands of Culebra and Vieques and in the U.S. Virgin Islands, including St. Thomas, St. John, and St. Croix. A storm surge will raise water levels by as much as 1 to 3 feet above normal tide levels in the British Virgin Islands. Near the coast, the surge will be accompanied by large and destructive waves. SURF: Swells generated by Ernesto are affecting portions of the Leeward Islands, the Virgin Islands, Puerto Rico and the Dominican Republic. These swells will reach the Turks and Caicos Islands and southeastern Bahamas today, and Bermuda and the rest of the Bahamas on Thursday. Swells are expected to reach the east coast of the United States Thursday night and continue into the weekend. These swells are likely to cause life-threatening surf and rip current conditions.
