Flood watch
A Flood watch is issued when weather conditions are favorable for very heavy rain and flash flooding. A watch does not mean that flooding is actually occurring, only that conditions have created or will create a significant risk for it. If flooding actually does occur, a flood warning and urgent action should be taken. Formerly, flood watches were issued separately from flash flood watches; however, the two were recently merged into a single product. In the United States, the National Weather Service issues watches and warnings for flooding on a per-county basis.
