A Tropical Storm Warning continues from the South Santee River, South Carolina, to Cape Lookout, and a Tropical Storm Watch continues from Edisto Beach, South Carolina, to South of the South Santee River.Interests elsewhere in eastern North Carolina should monitor the progress of Ana.

Tropical storm conditions are expected within the warning area, and possible within the watch area, by this afternoon or evening.

The combination of storm surge and the tide will cause normally dry areas near the coast to be flooded by rising waters.

The water could reach one to two feet above ground at times of high tide in coastal areas from Cape Hatteras, North Carolina southward through South Carolina.

Tropical Storm Ana is expected to produce rainfall accumulations of one to three inches, with isolated amounts of five inches, over eastern portions of North Carolina and South Carolina through Monday, according to the post.
