On Sunday, the National Weather Service had two storm survey teams out to gather information about the damage left behind from the storms on Saturday.

The NWS Released the following statement on Sunday evening, indicating the surveys will continue on Monday:

"Investigation of Saturday’s tornadoes from Van Buren to Kent County will continue on Monday. Survey teams have confirmed tornado damage did occur in Van Buren, Allegan, SE Ottawa, and Kent Counties. However, surveys need to be completed before more detailed information can be provided. There is preliminary evidence of EF-1 damage in Van Buren, Allegan, and Ottawa Counties, and EF-0 damage in Kent County.  Survey teams will provide additional information Monday."

How strong are EF-0 and EF-1 tornadoes? An EF-0 tornado has wind speeds between 65-85 mph. An EF-1 tornado has winds of 86-110 mph.

It has still not been determined if this was one tornado or several. It has also not been determined how long this tornado was actually on the ground.
