Understanding the NWS Flash Flood Warning

A flash flood warning from the NWS signifies an extremely dangerous situation. In South Florida, where sudden downpours are common, this warning indicates that flash flooding is already occurring or is imminent. Understanding the terminology is crucial. A flash flood is a rapid, often unexpected, flooding of normally dry areas. Heavy rainfall, exceeding the ground's absorption capacity, is the primary cause. A flood watch, on the other hand, suggests that conditions are favorable for flooding, giving residents time to prepare.

• Watch vs. Warning: A watch means conditions could lead to flooding; a warning means flooding is happening or will happen soon. The urgency is significantly higher with a warning.
• Urgency: A flash flood warning requires immediate action. Delaying response can be life-threatening.
• Warning Dissemination: The NWS disseminates warnings through various channels, including weather alert apps on smartphones, local news broadcasts, and the official NWS website.
