Rain will develop after midnight tonight and continue through Saturday morning before tapering off early in the afternoon. Rainfall amounts will generally average between 1 and 2 inches, however locally higher amounts will be possible, especially across Long Island and eastern Connecticut.

The combination of heavy rainfall and leaf-clogged drainages will pose a threat for flash flooding across the watch area. In addition, rising tides Saturday morning pose an enhanced threat for flash flooding across low lying portions of coastal communities. If the heavy rainfall axis works into the flashy river basins of Northeastern New Jersey And The Lower Hudson Valley, Quick Water Level rises would be expected across small rivers, streams, and creeks, with flooding of adjacent areas.
