...FLASH FLOOD WATCH HAS EXPIRED...

The Flash Flood Watch for portions of southern Connecticut and
southeast New York has expired. 

* The last of Elsa's tropical rain bands has departed.

* Otherwise, considerable residual flooding will likely be slow to
  subside for southwestern Connecticut this afternoon, with rises
  on a few larger stem rivers likely into Saturday. Please avoid
  any flooded areas, areas adjacent to fast moving rivers and
  streams, and please heed any road closures.

* Scattered showers and thunderstorms will move into the region
  between 6 and 10 pm. The threat for flash flooding with this
  activity is low and isolated as movement with any individual
  storm will limit rainfall, but any cell interactions or training
  on already saturated grounds presents a non-zero threat.
