Flood alert

Flood alert

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.fact|date=May 2008 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.

A flood warning or flash flood warning is issued when flooding in a certain area is imminent or occurring.

Flood alerts by country

In Canada, a heavy rainfall warning (which indicates rainfall amounts that "could" produce flooding are expected) has basically the same meaning as a flood watch.

In the United States, the National Weather Service issues watches and warnings for flooding on a per-county basis. When a flood warning is issued in the United States it means a river or creek is in flood.

In Australia, the Bureau of Meteorology issues a flood watch that covers similar conditions to the United States Flood Watch, however, it is known by slightly different names in some states.
