Understanding Our Flood Warning Maps

FloodWarn delivers real-time tracking of various flood-related alerts through specialized interactive maps, helping you stay informed and safe during dangerous flood events.

Types of Flood Alerts We Track

  • •Flash Flood Warning: Take Action! A Flash Flood Warning is issued when a flash flood is imminent or occurring. If you are in a flood prone area move immediately to high ground. A flash flood is a sudden violent flood that can take from minutes to hours to develop. It is even possible to experience a flash flood in areas not immediately receiving rain.
  • •Flood Warning: Take Action! A Flood Warning is issued when the hazardous weather event is imminent or already happening. A Flood Warning is issued when flooding is imminent or occurring.
  • •Flood Advisory: Be Aware: A Flood Advisory is issued when a specific weather event that is forecast to occur may become a nuisance. A Flood Advisory is issued when flooding is not expected to be bad enough to issue a warning. However, it may cause significant inconvenience, and if caution is not exercised, it could lead to situations that may threaten life and/or property.
  • •Flood Watch: Be Prepared: A Flood Watch is issued when conditions are favorable for a specific hazardous weather event to occur. A Flood Watch is issued when conditions are favorable for flooding. It does not mean flooding will occur, but it is possible.

What is a Flash Flood Warning?

A Flash Flood Warning means a flash flood is imminent or occurring. These are dangerous, fast-moving floods. If you are in a flood prone area move immediately to high ground. It is even possible to experience a flash flood in areas not immediately receiving rain.

How To Use

  • • Toggle radar layer
  • • Adjust opacity for better visibility
  • • Play/pause radar animation to track storm movement

Why It Matters

Combining flood warnings with radar helps you visualize active threats and understand storm movement in your area.

Recent Expired Warnings

Shows flood warnings from the past to analyze recent patterns.

How To Use

  • • Review past warning polygons to see affected areas
  • • Compare with current conditions using the map style selector
  • • Click on any warning to view detailed information
  • • Use radar overlay to see how storms tracked

Why It Matters

Historical data helps identify patterns and verify whether areas that received warnings were actually impacted by flooding.

Map Controls Explained

1

Radar Controls

Our radar layer shows precipitation intensity from light rain (blue) to intense storms (red/purple).

  • • Animation controls let you play through the last hour of radar to track storm development and movement direction
  • • Opacity control helps blend radar with other map features for optimal visualization

Our Data Sources

FloodWarn combines multiple official data sources to provide comprehensive flood monitoring:

National Weather Service Warnings

Official flood warning polygons with precise geographic boundaries.

RainViewer Radar

High-resolution radar imagery showing precipitation intensity and storm cells.

Mapbox Visualization

Professional mapping platform for interactive visualization and geographic analysis.

Data is automatically refreshed every 30-60 seconds for warnings (more frequently when active warnings exist) and every 5 minutes for radar imagery to ensure you have the most current information available.

Flood Safety Tips

  • • Turn Around, Don't Drown! Never drive through flooded roadways.
  • • Move to higher ground if a Flash Flood Warning is issued for your area.
  • • Be aware of streams, drainage channels, canyons, and other areas known to flood suddenly.
  • • If you live in a flood-prone area, have an evacuation plan.
  • • Monitor our live maps and local weather alerts during flood events.
