Bu Erp A.6 Severe Weather Plan A.6 Severe Weather Plan Creation Date: 05/22/2009 Revised Date: 06/10/2015 Emergency Response Plan Review Date: 7/3/2017 Page 1 of 10 BU ERP A.6 SEVERE WEATHER PLAN 1.0 Purpose 1.1 The purpose of this Severe Weather Response Plan is to minimize the impact on the University from a severe weather incident 2.0 ApplicaBility 2.1 This Severe Weather Plan applies to all students, faculty, staff and contractors of Boston University 3.0 Assumptions 3.1 Living in New England, we are susceptible to severe weather, usually in the form of blizzards and winter storms, Nor’easters, and hurricanes. It is not unusual to experience periods of extreme hot and cold temperatures. 3.2 In the case of all such possibilities, modern meteorology has allowed us to have advance warnings. 3.3 With such warnings, the University will be able to take such steps necessary to minimize the effect of a severe weather incident 3.4 The one severe weather incident that may occur without much warning is a tornado or microburst. While the region has experienced such events in the past, they are not rated as having a high probability in the city of Boston. 4.0 Definitions: 4.1 The following are National Weather Service criteria for issuing Watches/ Advisories and Warnings: 4.1.1 Watches: 50% confidence of meeting Warning criteria (generally within 36-48+ hours) 4.1.2 Advisories and Warnings; 80% confidence in the event of occurrence (generally within 24 – 36 hours) 1 A.6 Severe Weather Plan Creation Date: 05/22/2009 Revised Date: 06/10/2015 Emergency Response Plan Review Date: 7/3/2017 Page 2 of 10 4.2 Winter Storm WATCH – issued by the National Weather Service when there is a potential for heavy snow or significant ice accumulations, usually at least 24 to 36 hours in advance. The criteria for this watch can vary from place to place. 4.3 Winter Storm WARNING – issued by the National Weather Service when a winter storm is producing or is forecast to produce heavy snow or significant ice accumulations. The criteria for this warning can vary from place to place. 4.4 Blizzard WARNING – Issued for winter storms with sustained or frequent winds of 35 mph or higher with considerable falling and/or blowing snow that frequently reduces visibility to 1/4 of a mile or less. These conditions are expected to prevail for a minimum of 3 hours. 4.5 Severe Weather - a severe thunderstorm as having large hail, at least 3/4 inches (0.75 inches) in diameter, and/or damaging winds, at least 58 mph, or 50 knots. 4.6 Severe Thunderstorm WATCH - when conditions are favorable for the development of severe thunderstorms over a large area. You should go about your normal business, but pay close attention to the weather. 4.7 Severe Thunderstorm WARNING - when its state-of-the-art doppler radar indicates that a severe storm is imminent or occurring, or if a timely, reliable report of large hail (1” in diameter) or damaging winds has been received. You should seek immediate shelter until the storm has passed 4.8 MicroBurst - a sudden rush of cool air toward the ground that can impact with speeds greater than 70 mph and produce damage similar to that of a tornado. Viewing the damage from the air does not reveal evidence of a twisting motion or convergence toward a central track, like it would for a tornado 4.9 Hurricanes - A tropical system in which the maximum sustained surface wind is 64 knots (74 mph) or greater. This is the worst and strongest of all tropical systems. 4.10 Hurricane Watch - An announcement for specific areas that hurricane conditions pose a possible threat to coastal areas within 36 hours. In New England, due to 2 A.6 Severe Weather Plan Creation Date: 05/22/2009 Revised Date: 06/10/2015 Emergency Response Plan Review Date: 7/3/2017 Page 3 of 10 the rapid acceleration of most of our hurricanes, it is a necessity that you take action during the watch. 4.11 Hurricane Warning - A warning that hurricane conditions, including sustained winds of 74 mph or greater, associated with a hurricane are expected in a specified coastal area within 24 hours or less. Any preparedness measures must be rushed to completion once the warning is issued. High winds and coastal flooding will develop many hours before the eye of the storm actually comes ashore. 4.12 Tornado - a violently rotating column of air in contact with the ground and extending to the thunderstorm base. It can be a few yards across to a mile wide 4.13 Heat Advisory – Heat Advisory is defined as when the daytime heat index falls between 100 degrees Fahrenheit and 104 degrees Fahrenheit for two or more hours. 4.14 Heat Wave - heat wave is defined as three or more days of temperatures equal to or greater than 90 degrees Fahrenheit. 5.0 Notifications 5.1 Boston University’s Director of Emergency Management (DEM) will be notified in advance of any possible severe weather incident. This notification may come in the form of National Weather Alerts, NOAA Weather Radio Warnings, or alerts from Boston and Massachusetts Emergency Management Personnel. 5.2 The DEM will notify the appropriate members of the BU Incident Command Response Team of the possible severe weather incident and to take appropriate actions. 3 A.6 Severe Weather Plan Creation Date: 05/22/2009 Revised Date: 06/10/2015 Emergency Response Plan Review Date: 7/3/2017 Page 4 of 10 6.0 Roles and ResponsiBilities 6.1 DEM – monitor National Weather Service daily forecasts and alerts as well as NOAA weather radio for severe weather.

  • The Fujita Scale Is Used to Rate the Intensity of a Tornado by Examining the Damage Caused by the Tornado After It Has Passed Over a Man-Made Structure
    The Fujita Scale is used to rate the intensity of a tornado by examining the damage caused by the tornado after it has passed over a man-made structure. The "Percentage of All Tornadoes 1950- 1994" pie chart reveals that the vast majority of tornadoes are either weak or do damage that can only be attributed to a weak tornado. Only a small percentage of tornadoes can be correctly classed as violent. Such a chart became possible only after the acceptance of the Fujita Scale as the official classification system for tornado damage. It is quite possible that an even higher percentage of all tornadoes are weak. Each year the National Weather Service documents about 1000 tornado touchdowns in the United States. There is evidence that 1000 or more additional weak tornadoes may occur each year and go completely undocumented. The "Percentage of Tornado-Related Deaths 1950-1994" pie chart shows that while violent tornadoes are few in number, they cause a very high percentage of tornado-related deaths. The Tornado Project has analyzed data prior to 1950, and found that the percentage of deaths from violent tornadoes was even greater in the past. This is because the death tolls prior to the introduction of the forecasting/awareness programs were enormous: 695 dead(Missouri-Illinois-Indiana, March 18, 1925); 317 dead(Natchez, Mississippi, May 7, 1840);.255 dead(St. Louis, Missouri and East St. Louis, Illinois, May 27, 1896); 216 dead(Tupelo, Mississippi, April 5, 1936); 203 dead(Gainesville, GA, April 6, 1936). In more recent times, no single tornado has killed more than 50 people since 1971.

  • Temperature Change and Its Effects on the Great Lakes Climate
    Temperature Change and its Effects on the Great Lake’s Climate. Ross Ellet Professor: Matthew Huber April 28, 2005 Temperature change and its effects on the Great Lakes climate. The Great Lakes create a very unique sub climate zone that is unlike most areas in the world. The Great Lakes act as a climate moderator. They contain some of the biggest fresh water lakes in the world. This allows temperature moderation to occur. Typically the lakes keep the eastward coastlines more humid. Since there is more humidity, clouds are more frequent. Thus the temperature fluctuation on a daily basis is a little less than areas not affected by the Great Lakes. This in turn affects the precipitation that falls, when it falls, and where it falls. In the winter time the cold air masses blow over the relatively warm water which creates lake-effect snowfall. This is a very important social and economical impact the climate has on the Great Lakes region. So what happens when a climate change occurs in this area? What types of impacts will it have on the Great Lakes region? Will it be any different than those areas directly west of the Great Lakes? Theory and Research Aral Sea In order to understand climate change in the Great Lakes, first one must understand the dynamics of what is already occurring. The Great Lakes is unlike most lakes in the world due to its size, power, and potential to affect climate. However, there is another body of water that is just as significant. The Aral Sea, which is located in Uzbekistan and Kazakhstan, is an important tool to see how much a large body of water affects climate.

  • Hurricane Knowledge
    Hurricane Knowledge Storm conditions can vary on the intensity, size and even the angle which the tropical cyclone approaches your area, so it is vital you understand what the forecasters and news reporters are telling you. Tropical Depressions are cyclones with winds of 38 mph. Tropical Storms vary in wind speeds from 39-73 mph while Hurricanes have winds 74 mph and greater. Typically, the upper right quadrant of the storm (the center wrapping around the eye) is the most intense portion of the storm. The greatest threats are damaging winds, storm surge and flooding. This is in part why Hurricane Katrina was so catastrophic when bringing up to 28-foot storm surges onto the Louisiana and Mississippi coastlines. A Tropical Storm Watch is when tropical storm conditions are possible in the area. A Hurricane Watch is when hurricane conditions are possible in the area. Watches are issued 48 hours in advance of the anticipated onset of tropical storm force winds. A Tropical Storm Warning is when tropical storm conditions are expected in the area. A Hurricane Warning is when hurricane conditions are expected in the area. Warnings are issued 36 hours in advance of tropical storm force winds. Here are a few more terms used when discussing hurricanes: Eye: Clear, sometimes well-defined center of the storm with calmer conditions. Eye Wall: Surrounding the eye, contains some of the most severe weather of the storm with the highest wind speed and largest precipitation. Rain Bands: Bands coming off the cyclone that produce severe weather conditions such as heavy rain, wind and tornadoes.
