With warm temperatures and melting snow filling creeks and rivers, the National Weather Service has put a flood watch in effect until 6 this evening.
The runoff from Saturday's rain and snow melt from today may cause some flooding on rivers and creeks, the weather service said. In addition, above-freezing temperatures causing snow and ice to melt, combined with rain, could cause ice to break up and jam.
There have already been reported of ice jams and localized flooding in parts of the area, and the possibility of localized flooding will continue into this afternoon, the weather service said.
A flood watch means there is a potential for flooding.
Ice jams, the weather service noted, can occur suddenly and are highly unstable. Water can back up quickly behind an ice jam and flood an area in a matter of minutes. When ice jams break, they can also cause a sudden release of water that can flood areas downstream.
