All but one section of the Saw Mill River Parkway was reopened by Friday night after rain deluged the Hudson Valley.
As of 8 p.m., the Saw Mill was closed in both directions in Mount Pleasant near Pace University due to flooding. The closed section ranged from Route 117 to Exit 27, authorities said.
Other sections of the parkway were reopened earlier Friday night, but authorities told drivers to exercise caution, and water levels on the adjacent river remained high. Sections of the parkway could flood again, they cautioned, as forecasts called for rain to continue through the night and into Saturday. Up to a quarter inch of rain could fall before Saturday morning, forecasts predicted, and that amount could double as the rains continue through the day.
Authorities were advising drivers to use Interstate 684 and the Taconic State Parkway as alternatives. On the Tappan Zee Bridge, signs warned drivers of speed restrictions from the toll barrier to the South Nyack exit because of the rain and slippery road conditions.
The northbound Hutchinson River Parkway was experiencing volume delays about 1:15 p.m., from the Bronx line up to the Cross County Parkway exit in Eastchester and again further north near the Mamaroneck Avenue exit, News 12 reported.
An accident was slowing eastbound traffic on Interstate 287 at Exit 10 in Rye Brook, the state Department of Transportation reported, and the Thruway Authority reported delays northbound between the Tappan Zee Bridge and Exit 14, a span of six miles.
Traffic conditions appeared normal in Orange, Putnam and Dutchess counties, News 12 reported.
Rockland County was faring better. The Rockland County Sheriff's Department and Clarkstown police reported no weather-related closures or delays, while Orangetown police said flash flooding that had impeded travel Thursday had cleared up by Friday morning.
Metro-North train service was running on schedule. Extra outbound trains from Grand Central Terminal were running between noon and 4 p.m. for those starting their Memorial Day weekends early. Some evening peak hour trains were to be canceled or combined to accommodate the shift in passenger volume.
WET WEATHER LINGERS
An approaching cold front will make for a soggy start to the weekend, forecasters said.
Showers and isolated thunderstorms are possible Friday as rain continues through Saturday night, National Weather Service meteorologist Joe Pollina said. By the time the storm system clears, up to an inch of rain may soak the area.
News 12 meteorologist Brysen Van Eck said he doesn't expect the rain to add to the flooding.
"The heavy downpours are pretty much out of the way," he said.
The City of Yonkers was providing sandbags to residents living in flood-prone areas in anticipation of more flash flooding, Mayor Mike Spano said.
Sandbags can be picked up until 7 p.m. Friday and again from 7 a.m. to 3 p.m. Saturday at the Yonkers Organic Waste Yark on Nepperhan Avenue, The Associated Press reported.
Friday's temperatures were expected to hover between the high 50s and the lower 60s.
