Flood alerts are issued by government weather agencies to alert residents that flood conditions are a possibility for their area.
Types of flood alerts
A flash flood watch is issued when weather conditions are favorable for very heavy rain and flash flooding. Formerly, flood watches were issued separately from flash flood watches; however, the two were recently merged into a single product. 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.
