DISCUSSION AND 48-HOUR OUTLOOK ------------------------------ At 1100 AM AST (1500 UTC), the center of Tropical Storm Harvey was located near latitude 13.9 North, longitude 68.1 West. Harvey is moving toward the west near 22 mph (35 km/h) and this general motion is expected to continue through Sunday. A turn toward the west-northwest is expected Sunday night or Monday. On the forecast track, the center of Harvey will move across the central and western Caribbean Sea over the weekend. Maximum sustained winds are near 40 mph (65 km/h) with higher gusts. Satellite imagery and reports from an Air Force Reserve Hurricane Hunter aircraft indicate that Harvey is currently poorly organized, and only slow strengthening is expected during the next 48 hours. Tropical-storm-force winds extend outward up to 70 miles (110 km) mainly to the northwest of the center. The estimated minimum central pressure based on Hurricane Hunter data and data from NOAA buoy 42059 is 1007 mb (29.74 inches).
