Things are going to be a little noisy at 1:45 p.m. Thursday afternoon as tornado sirens are activated across the state.

Relax, it's only a test to remind residents to be prepared in the event of dangerous weather.

For most areas, the exercise will be repeated at 6:45 p.m. That won't be the case in Milwaukee County, where officials have decided to forgo the evening test to avoid alarming thousands of Milwaukee Bucks fans that will be making their way into the BMO Harris Bradley Center for a playoff game, said Tod Pritchard, spokesman for the state Division of Emergency Management.

The spring testing of the sirens comes along with test alerts that will be broadcast by radio and television stations around the state at 1:45 and 6:45 p.m.

"The goal is to get people ready for severe weather season," Pritchard said, adding that homeowners and businesses should have - or create - plans for keeping everyone safe.
