Update from the National Hurricane Center

According to the National Hurricane Center’s Advisory #19, issued at 2100z:

At 500 PM EDT (2100 UTC), the center of Tropical Storm Isaias was located by an Air Force Reserve reconnaissance aircraft near latitude 25.1 North, longitude 78.7 West. Isaias is moving toward the northwest near 10 mph (17 km/h). A general northwestward motion with some decrease in forward speed is expected for the next day or so, followed by a north-northwestward motion by late Sunday and a turn toward the north and north- northeast on Monday and Tuesday with an increase in forward speed. On the forecast track, the center of Isaias will approach the southeast coast of Florida tonight and move near or along the east coast of Florida Sunday and Sunday night. On Monday and Tuesday, the center of Isaias will move quickly from offshore of the coast of Georgia into the southern mid-Atlantic states.

Maximum sustained winds have decreased to near 70 mph (110 km/h) with higher gusts. Some restrengthening is forecast, and Isaias is expected to regain hurricane strength tonight. Slow weakening is expected to begin Sunday night and continue through Monday.

Tropical-storm-force winds extend outward up to 105 miles (165 km) from the center. During hew past couple of hours, a Weatherflow observing site at the Dania Pier in Broward County, Florida, reported a wind gust to 59 mph (94 km/h) in an outer rainband. More recently, a wind gust to 41 mph (67 km/h) was reported by a Weatherflow site in Juno Beach, Florida.

The estimated minimum central pressure based on reconnaissance aircraft data is 993 mb (29.33 inches).
