Orange, Sullivan and Ulster counties remain under a flood watch until 7 p.m. Saturday.

The National Weather Service says a combination of rainfall that will be heavy at times, melting snow and temperatures rising into the 50s or even approaching 60 in some places will create the possibility of flooding, especially in urban and poorly drained areas.

At least one to two inches of rain is expected in Sullivan and Ulster counties, and one to three inches is forecast in Orange County. Locally heavier amounts are possible. The heaviest rainfall is expected Friday morning.

Ice jams could form on rivers and streams that had frozen over during the recent cold spell.

Sullivan County’s Office of Emergency Management advised all residents living in areas prone to flooding to monitor news reports for updates and to be prepared to evacuate if necessary.
