Isaias remains a tropical storm as of 11 p.m. Saturday, but it may re-strengthen into a hurricane as it approaches Florida's east coast overnight.

As of 11 p.m., Isaias was located about 80 miles east-southeast of Fort Lauderdale and 105 southeast of West Palm Beach. Maximum sustained winds continued at 70 mph with higher gusts. It slowed down slightly and is moving to the northwest at 9 mph.

The storm is expected to keep moving in a northwest direction with some decrease in forward speed through Sunday, followed by a turn toward the north-northwest by late Sunday and the north-northeast Monday and Tuesday. The storm is also expected to pick up forward speed after the latter move.

On its current track, the storm’s center is forecast to approach the southeast coast of Florida Saturday night into early Sunday and move near or along the east coast of Florida Sunday and Sunday night.

Some re-strengthening of Isaias is forecast, with the storm expected to regain hurricane strength early Sunday. Slow weakening is expected to begin Sunday night and continue through Monday.

According to meteorologists with the Florida Public Radio Emergency Network, Miami will feel the first effects of Isaias, as tropical storm-force winds are expected Saturday night.

Hurricane conditions are expected to reach the east coast of Florida between Boca Raton and the Volusia/Flagler County Line on Sunday and will spread northward through Sunday night.

Tropical storm conditions are expected within the tropical storm warning area of south of Boca Raton to north of Ocean Reef, Lake Okeechobee, and from the Volusia/Flagler County Line to Ponte Vedra Beach.

Tropical storm conditions are also possible in northeast Florida to South Carolina on Monday.

Isaias could produce 2-4 inches of rain, with isolated maximum totals of 6 inches.

Storm surge could be higher if Isaias take a more westerly turn, meteorologists said.

Conditions should begin to improve in Northeast Florida by midday Monday, as Isaias accelerates from off the coast of Georgia into the southern Mid-Atlantic States on Monday and Tuesday.
