Beaufort County has seen plenty of rain the first three days of this week, but Tropical Storm Andrea forming in the Gulf of Mexico could dump 2 to 4 more inches on the county, a National Oceanic and Atmospheric Association meteorologist said Wednesday.
Rain from the system would probably be heaviest Thursday night, but heavy rain was expected through Friday morning, according to meteorologist Jonathan Lamb.
A new moon this weekend will also bring tides that are higher than usual, increasing the probability of flooding in some areas, he said.
The first named storm of Atlantic season, Andrea, was likely to bring wet weather to parts of Florida's west coast by the end of the week.

Forecasters issued a tropical storm warning for the west coast of Florida from Boca Grande to the coast south of Tallahassee.
Andrea had maximum sustained winds near 40 mph, according to a 6 p.m. weather outlook. It was moving toward the north at about 3 mph, and forecasters expected the storm to continue moving northeastward at a faster speed Thursday.
The center of Andrea was expected to reach the coast of the Florida Big Bend this afternoon or evening and move over southeastern Georgia and eastern South Carolina tonight and Friday.
Heavy rain this week has already caused problems in northern Beaufort County.
A storm knocked down power lines and might have been a factor in two car accidents at the same spot along Trask Parkway on Wednesday morning, according to the Burton Fire District.
Both accidents occurred near the parkway's intersection with Roseida Road, and both shut down one of the two southbound lanes on Trask Parkway for more than 30 minutes. No injuries resulted from either accident.
Burton firefighters and Beaufort County EMS responded to the first accident just after 9:30 a.m. The crash caused moderate damage to the two vehicles involved. The second accident occurred at 11 a.m. and also caused moderate damage to two vehicles.
Firefighters were called for downed power lines along Ramblin Road at about 11 a.m. After firefighters secured the area, SCE&G crews repaired the lines.
