A flash flood watch is also in effect until Thursday morning for all three counties.
According to NWS, the remnants of Hurricane Ida will pass through the region Wednesday during the day and evening. Periods of heavy rain and scattered thunderstorms associated with this low will result in widespread 1 to 4 inches of rain, with locally higher amounts by Thursday morning.
Additionally, much of this rainfall may occur in a short period of time, exacerbating the flooding threat. Combined with wet conditions, this will lead to instances of flash flooding, officials said.
Flooding of creeks, streams, urban areas and poor-drainage areas is possible. Water is likely to cover the roads, especially in low-lying areas. Roads and structures near rivers may be flooded.
