Critical Values & Thresholds <br />Because duration is such an important component of the wind loadings and total impacts, no firm <br />thresholds have been determined for non -convective wind speeds. However, research has shown that <br />some impacts emerge when gusts exceed 60 mph. When gusts exceed 75mph, impacts are often <br />widespread, and casualties tend to increase dramatically. <br />4.3.12.11. Preparedness <br />If planning to be outdoors for a significant length of time, be aware of the weather forecast, especially if <br />you will be well -removed from sturdy shelter. Stay "connected" via television, radio, NOAA Weather <br />Radio, or social media. Non -convective high wind events rarely occur without warning, although warning <br />lead times may be comparatively limited during the evolution of an extreme wind episode. Because <br />protracted and extensive electrical and communication disruptions may occur, set aside emergency water <br />and food supplies, can openers, batteries, and flashlights. <br />201 <br />
