This water vapor image shows Tropical Storm Bonnie stalled off the coast of South Carolina.
Heavy rains from Tropical Storm Bonnie soaked the coasts of South Carolina, southeastern North Carolina and eastern Georgia, ruining the start of Memorial Day weekend even as it weakened while moving northward.
Top sustained winds of the season's second-named tropical storm decreased to 40 mph Sunday morning, making, four days before the official start of hurricane season in the Atlantic Ocean, according to the National Hurricane Center.
Despite losing a bit of momentum, Tropical Storm Bonnie will move north to bring heavy rains to the Philadelphia region on Sunday night into Monday morning.
Showers are expected to move into the southern areas of region, including the South Jersey beach towns and the Delaware beaches, as early as Sunday morning, but later in the afternoon in most areas, according to the National Weather Service. Points north of the city could remain dry all day.
The heaviest rain should occur in the overnight hours with more than 2 inches of rain possible in many areas, and locally higher amounts possible. Localized flooding is possible.
Showers will likely disrupt Memorial Day festivities in the morning before they gradually decrease through the afternoon and evening, forecasters said.
