DISCUSSION AND OUTLOOK
———————-
At 200 PM AST (1800 UTC), the center of Tropical Storm Karen was located near latitude 17.5 North, longitude 66.0 West. Karen has moved erratically during the past few hours as the center has re-formed a little to the west. However, it is expected to resume a motion toward the north near 8 mph (13 km/h) this afternoon. A north-northeastward motion with some increase in forward speed is forecast tonight through Wednesday night. On the forecast track, the center of Karen will pass near or over Puerto Rico and the Virgin Islands this afternoon and then move over the western Atlantic tonight and Wednesday.
Reports from an Air Force Reserve Hurricane Hunter aircraft indicate that maximum sustained winds are now near 45 mph (70 km/h) with higher gusts. Additional slow strengthening is expected during the next couple of days.
Tropical-storm-force winds extend outward up to 80 miles (130 km) mainly to the southeast of the center. Surface observations indicate that wind gusts to tropical-storm force are occurring over portions of the Virgin Islands and southeastern Puerto Rico.
The minimum central pressure estimated from Air Force Reserve Hurricane Hunter aircraft data and surface observations is 1005 mb (29.68 inches).
