Tropical Storm Chris continues to spin just off the North Carolina coast and is now centered roughly 150 miles to the south of Cape Hatteras, North Carolina.
Forecasters expect it will gain hurricane strength later on Monday before moving up Gulfstream waters on a path that won't take it near the USA mainland but could cause life-threatening surf on East Coast beaches this week.
Tropical Storm Chris is expected to gain strength, possibly attaining hurricane status by late Tuesday or Wednesday.
Meanwhile, a tropical depression formed in the Atlantic well off the North Carolina coast, but forecasters said there were no coastal watches or warnings in effect.
Tropical Storm Beryl, downgraded from a category one hurricane, remains on a slow course towards the Lesser Antilles. Marshall Alexander, with Dominica's Meteorological Service, told The Associated Press that no landslides or widespread flooding have been reported.
At 11 a.m. EDT on Sunday, the storm's center was located about 160 miles south of Cape Hatteras, North Carolina with maximum sustained winds around 45 mph.
The disturbance is expected to move west-northwest for the next day or so, passing over the Virgin Islands and Puerto Rico on Monday and then over Hispaniola on Monday night.
Swells generated by the system were expected to increase and affect portions of the coasts of North Carolina and the Mid-Atlantic states into early next week, forecasters said, and rip current conditions may be possible.
It might reach Nova Scotia by Thursday, though Environment Canada said it's still unsure about the forecast track and the system's intensity. The storm's remnants crossed directly over the island with top sustained winds of 65 kph, and was expected to drop up to eight centimetres of rain, with as much as 13 centimetres in isolated spots.
Tropical Storm Beryl was downgraded on Sunday as it moved through the Lesser Antilles. "We're a little bit scared because of what we've been through", said Jose Bultron, a delivery man in the southeast town of Humacao.
"Lugo lost his roof and two walls to Maria, and was waiting on Sunday for volunteers to secure his new roof before Beryl arrives". Maximum sustained winds have increased to near 60 miles per hour, with higher gusts. It said Beryl could reform into a tropical cyclone in a few days when its remnants are forecast to move through the Bahamas.
