The Pearl River is expected to rise above flood stage on the afternoon of April 19.
However, forecasters say that rise shouldn't affect homes and streets on the Northside.
Flash flooding, though, is a possibility, with three to five inches of rain expected to fall in the area from late Sunday to Sunday night.
On Saturday, April 18, the National Weather Service in Jackson issued a flood warning for the river in Hinds and Rankin counties. The river was expected to surpass flood stage Sunday, and rise to 29.5 feet Monday morning.
The agency also issued an elevated threat for flash flooding, citing the amount of rain expected to fall Sunday afternoon to Sunday night/early Monday morning.
The river was at 24.1 feet Saturday; forecasts were based on rainfall that has already fallen and will fall within the next 48 hours.
According to the NWS website, the river, at 29.5 feet, will not affect the Northside.
Forecasts were expected to be updated on the evening of April 18.
