MIAMI, Florida (CNN) -- A tropical storm warning stretching from the north Florida coast to the Georgia-South Carolina border was downgraded to a watch Monday evening as Tropical Storm Edouard continued to drift off the coast.

As of 11 p.m., Edouard with maximum sustained winds of 40 mph was about 175 miles east of Jacksonville, Florida. The storm was nearly stationary.

With the tropical storm warning being dropped, the watch now extends from Titusville, Florida, to the South Santee River in South Carolina.

"It's just drifting around," said Robert Molleda, a meteorologist with the National Hurricane Center.

He said the storm was expected to remain "slow and erratic" in the coming days. The heaviest rain accompanying the storm is east of Edouard's eye, so the land areas closest to the storm have yet to be seriously affected.

Tropical storm watches were in effect from north of Titusville, Florida, to Fernandina Beach and from the Savannah River to the South Santee River in South Carolina.

Forecasts from St. Augustine, Florida, to Savannah, Georgia, called for thunderstorms and strong winds during the day Monday.

Meanwhile, Tropical Storm Dolly -- which rushed toward hurricane strength (74 mph) late last week before backing off short of the mark and turning north well out to sea -- continued to weaken Monday.

The storm was centered 550 miles east-northeast of the Leeward Islands in the southeastern Caribbean Sea, moving north-northwest near 9 mph.

Dolly's sustained winds were 45 mph, and forecasters expected little change in strength over the next 24 hours.
