Ann Arbor was hit hard by a severe storm. Here’s what residents should know

A severe storm brought down trees and branches, powerlines and poles and even parts of buildings in Ann Arbor in the early morning hours of April 15.

Here’s what residents should know as city crews work to clean up streets and assess the damage.

Did a tornado hit Ann Arbor?

Yes. At 7:14 p.m. on April 15, following an investigation, the National Weather Service released a preliminary statement saying a tornado moved through Ann Arbor. Here's what the NWS said:

Rating:                 EF-1
Estimated Peak Wind:    110 mph
Path Length /statute/:  1.71 miles
Path Width /maximum/:   500 yards
Fatalities:             0
Injuries:               0

Start Date:             April 15, 2026
Start Time:             1:44 AM EDT
Start Location:         3 S Barton Hills / Washtenaw County / MI

The tornado started in the area of Jackson Ave near Interstate 94.  It
moved southeast across the interstate and then over Veterans Memorial
Park where it produced EF-1 damage. This damage included numerous
uprooted and snapped trees, along with snapped stadium light poles.
The greatest concentration of EF-1 damage occurred from Jackson Ave though
Veterans Memorial Park and into the nearby neighborhoods. The tornado
continued through residential areas where there were numerous trees snapped
and large downed tree limbs. The damage became more sporadic as is continued
to the southeast through Virginia Park. Portions of an elementary
school roof were blown off before the tornado lifted near W William St
and 4th St.  Once the tornado had lifted, there was additional damage that
occurred from straight line winds at the Yost Ice Arena where the metal roof
panels had been pulled from the building.

EF Scale: The Enhanced Fujita Scale classifies tornadoes into the
following categories:

EF0.....65 to 85 mph
EF1.....86 to 110 mph
EF2.....111 to 135 mph
EF3.....136 to 165 mph
EF4.....166 to 200 mph
EF5.....>200 mph

Was anyone hurt?

The city has received no reports of injuries in Ann Arbor.

How should I report damage?

For emergencies, including downed wire, call 911.

For nonemergency public works issues, including fallen trees, use A2FixIt.

Is the city getting rid of its outdoor warning sirens?

No. The city will continue to maintain its outdoor warning siren system.

Earlier this year, the city’s Emergency Management Office asked residents whether the sirens — used to signal events like tornado warnings issued by the National Weather Service — should be kept. The response was overwhelmingly in favor of maintaining them as an added layer of safety.

Public input closed on March 31. Officials are now reviewing feedback and preparing a report summarizing how residents prefer to receive emergency alerts, along with plans for future siren maintenance and operations. That report will be shared soon.

Following the sirens’ activation during a tornado warning overnight on April 15, the city wants to clearly reassure residents: the outdoor warning sirens are staying in place.

When will my trash be picked up?

Routes for curbside collections of trash, recycling and compost will continue as scheduled Wednesday, April 15, and throughout the remainder of the week, as access permits. Residents are asked to please leave their carts at the curb, and if access to streets is unavailable resulting in missed pickups, service will be provided the next day or as soon as possible.

Are parks open? What’s going on at Veterans Memorial Park?

Most city parks are open. However, visitors in the coming days should use caution, as hazards may not be immediately visible and staff continue to assess storm damage across the park system. Any damage in parks can be reported through the city’s A2 Fix It system.

Veterans Memorial Park is closed and people should stay away. The park sustained significant damage to its facilities and athletic fields. For safety reasons, and to allow crews to continue assessment and repairs, the entire park is closed until further notice.

It looks like more rain is in the forecast. How can I help?

With additional storms forecast this week, Ann Arbor residents are encouraged to help clear leaves and debris from nearby storm drains and catch basins if it is safe to do so. This can help prevent street flooding. Do not walk or drive through flooded areas, regardless of depth.

How can resident ensure they are getting emergency alerts?
