Western University has installed a second Whelen omni directional severe weather siren. On August 21, the siren was placed atop the Social Sciences building. This siren compliments the original city-first siren installed on the roof of Alumni Hall in 2012. It will increase the range of a warning to the northeast and northwest. A significant portion of southern Ontario, including London is known to experience severe weather. The area has been hit with several tornadoes as recently as this summer. In the case of weather emergencies, early warning tools accompanied by comprehensive emergency plans increase public safety. The sirens are intended to be heard outdoors. When a siren is heard, you should take immediate shelter indoors. The new siren will be tested during the week of August 25 to 29. This is part of the installation process. It is Western's intention to begin regular, audible tests of the weather sirens this fall. If a real weather emergency occurs during this particular testing period, additional messaging will be communicated through Western's homepage and other social media channels.
