Master Flood Alerts: Decipher Them for Maximum Safety

Michigan rivers are experiencing significant flooding as rain and snowmelt push already high water levels higher. Flash flood warnings, flood warnings, watches and advisories are in effect across the region.

Residents should learn to decipher flood alerts to protect lives and property. Knowing the differences between watches, advisories and warnings helps ensure maximum safety.

Where and when

The entire Upper Peninsula and northern Lower Peninsula were under a flood watch on Tuesday morning, April 14. Multiple rivers in northern Michigan have active flood warnings, flash flood warnings, and advisories.

Definitions of alerts

Flood warning

A flood warning means hazardous weather is imminent or already occurring. People should seek higher ground and evacuate if necessary.

Flash flood warning

A flash flood warning signals very rapid flooding is occurring or about to occur. Officials urge immediate movement to higher ground, especially in flood-prone areas.

Flash flood versus flood

Flash floods develop much faster, typically within six hours. Standard floods may form over days or weeks, according to the National Weather Service.

Flood advisory

A flood advisory indicates expected flooding that may become a nuisance. Conditions are not severe enough for a warning, but inconveniences can still threaten life or property.

Flood watch

A flood watch means conditions are favorable for flooding. Residents should prepare and stay alert for possible escalation to a warning.

What to do now

Follow National Weather Service guidance and local emergency instructions. Prepare early if you are in a watch or advisory area.

• Create a family communications plan.
• Assemble an emergency kit with essentials.
• Determine if your home is in a flood-prone area.
• Buy sandbags or other flood defenses for your property.
• Charge phones and electronics before storms arrive.
• Plan care for neighbors and pets.

When a warning is issued

If a flood or flash flood warning is issued, act immediately. Avoid walking or driving through flooded areas and move to higher ground.
