Emergency Warning Sirens Sound By Mistake In Several Northwest Suburbs

CHICAGO (CBS) -- A malfunction was to blame for the sound of emergency warning sirens on Thursday in several northwest suburbs.

The National Weather Service reported that the sirens activated in the Hoffman Estates area on Thursday afternoon. They were being tested and inadvertently went off, and should be disregarded, the NWS said.

There is no weather emergency or other emergency of any kind, and the main threats from the rainstorms on Thursday afternoon were lightning strikes and very heavy downpours.

The Village of Schaumburg also confirmed with the Northwest Central Dispatch System that its sirens went off as a result of a malfunction at 1:23 p.m. Thursday.

Mount Prospect reported the same happened there.

All this, of course, comes about five days after storms late Sunday night resulted in at least three tornadoes in the Chicago area – including an EF-3 tornado that caused serious damage to neighborhoods in Woodridge and Naperville in particular.

The Daily Herald reported that the Northwest Central Dispatch System is investigating why sirens in Elk Grove Village and Mount Prospect did not go off during the storms Sunday night. While no tornadoes touched down in those areas, they were placed under a tornado warning and the sirens should have sounded, the newspaper reported.
