Flooding, Rivers & Flash Flood Information

Check nearby river observations, official flood forecasts, rainfall guidance, satellite imagery, and trusted safety resources. Active National Weather Service warnings and local emergency instructions always take priority.

Active danger

Flash-flood warnings

A Flash Flood Warning means dangerous flooding is occurring or expected soon. Check the active alerts shown with your local forecast, move to higher ground when directed, and never enter flooded roads or low-water crossings.

Understanding gauges

River levels and flood stages

River gauges report observed water height or flow at a specific point. Action stage signals increasing concern; minor, moderate, and major flood stages describe progressively greater expected impacts. A gauge reading is local and does not describe every road or neighborhood nearby.

Rain and coast

Rainfall and coastal flooding

Heavy rain can cause flash flooding before rivers crest. Along the coast, storm surge, tides, waves, and onshore wind can flood areas even away from a river. Use official rainfall outlooks, tide and coastal-flood information, and local evacuation guidance together.

Turn Around, Don't Drown

Never drive into floodwater

Water can hide a washed-out road and may be deeper or faster than it appears. Obey barricades, choose another route, and move to higher ground when a flash-flood warning is issued. Keep Wireless Emergency Alerts enabled and follow instructions from local emergency management.
