loss of power and communications. Such events could require the use of transit system <br /> assets for evacuation purposes. <br /> • Winter weather <br /> Snow and ice storms can cause power failures, make roads dangerous or impassable, cause <br /> sidewalk hazards, and affect the ability to deliver transit service. <br /> • Tornado/hurricane <br /> High winds have the potential to cause flying debris, down trees and/or power lines, make <br /> roadways impassable or dangerous, damage facilities or vehicles and threaten the <br /> safety of passengers and employees. Such events could require the use of transit <br /> system assets for evacuation purposes. <br /> • Thunderstorms <br /> May trigger flash flooding, be accompanied by strong winds, hail or lightning, can possibly cause <br /> power or communication system outages, damage facilities and equipment and make <br /> roads dangerous or impassable. <br /> • Wildfire <br /> Whether natural or human-caused, are particularly dangerous in drought conditions, can <br /> reduce visibility, impair air quality, and have the potential to damage facilities, <br /> equipment and make roadways impassable. Such an event could require the use of <br /> transit system assets for evacuation purposes. <br /> • Earthquake <br /> Has the potential to cause extensive damage to buildings, water systems, power systems, <br /> communications systems, roads, bridges and other transportation infrastructure. Such <br /> events often overwhelm first responder resources. In coastal areas, tsunamis, or tidal <br /> waves, are a hazard following major earthquakes and underwater tectonic activity. A <br /> transit system's assets could be used for evacuation purposes after damage <br /> assessment. <br /> • Landslide/Avalanche <br /> Has the potential to close roadways, damage vehicles and facilities and injure employees and <br /> passengers. <br /> • Dust storm <br /> Usually arrives suddenly in the form of an advancing wall of dust and debris which may be miles <br /> long and several thousand feet high, and usually last only a few minutes.
