The addition of rain through the day could cause blocks of ice in north country waterways to break apart in to ice jams, which could cause flooding in the region.
Calls to St. Lawrence County Emergency Management werent returned by press time on Thursday to answer questions about the prospect of flooding in the county. An ice jam on the Raquette River earlier this winter had flooded the basements of several homes near Hannawa Falls.
National Weather Service Meteorologist Aaron Reynolds, said St. Lawrence, Jefferson and Lewis counties are under a winter weather advisory and a flood watch until late this afternoon to Saturday morning.
There will be rain and thunderstorms through the day Friday, Mr. Reynolds said.
High winds and rain are anticipated and a cold front is expected to cross all three counties through Saturday morning. The combination of rain and temperatures in the high 40s is expected to result in considerable runoff from snow melt with significant rises on area waterways. Mr. Reynolds that rain fall on frozen ground may also cause flooding on streets and areas of poor drainage. As of Thursday afternoon, Friday temperatures were expected to be in the 40s. Temperatures are expected to slowly drop to high 30s by tonight and continue to fall into the upper 20s by Saturday morning.
