Chapter 6 - Storm Preparation and Response Flashcards
process of repairing and re-establishing critical utility services to end users during utility storm response.
Restoration
the collective efforts of governments, utilities, contractors, first responders, and volunteers to bring relief to areas stricken by storms. In utility arboriculture, the combined efforts of utilities and contractors to mobilize and assist in the restoration of utility services.
Storm response
process of repairing damage and restoring services following a storm.
Storm recovery
personnel likely to be the first to arrive and assist in emergencies (including storms and other natural disasters) such as police, firefighters, paramedics, and others with specialized skills and equipment as needed.
First responders
length of a branch or trunk to be considered in evaluating the combination of forces that could lead to failure.
Lever arm
change in diameter over the length of trunks, branches, and roots.
Taper
statement issued by a government weather agency indicating a potential threat of severe or hazardous weather.
Watch (storm)
statement issued by a government weather agency indicating an imminent threat of severe or hazardous weather.
Warning (storm)
a large area of low atmospheric pressure, characterized by inward-spiraling winds.
Cyclone
effect that causes deflection of moving objects to the right in the Northern Hemisphere and to the left in the Southern Hemisphere due to the Earth’s rotation.
Coriolis force
cyclone that originates over the tropical oceans, including tropical depressions, tropical storms, hurricanes, and typhoons.
Tropical cyclone
regional term of the Western Hemisphere for a tropical cyclone with wind speeds 74 mph (119 km/h) and greater.
Hurricane
regional term (Western North Pacific) for a severe tropical cyclone.
Typhoon
classification scheme for hurricane intensity based on the maximum surface wind speed and the type and extend of damage done by the storm.
Saffir-Simpson Scale
rise and onshore flow of seawater as the result of the winds of a storm, and also the surface pressure drop near the storm center.
Storm surge
cyclonic-scale storm that is not a tropical cyclone, usually referring to cyclones of middle and high latitudes.
Extratropical cyclone
local storm produced by a cumulonimbus cloud and accompanied by lightning and thunder, with strong gusts of wind, heavy rain, and sometimes hail.
Thunderstorm
complex of thunderstorms that travels more than 240 miles (386 km), with wind speeds greater than 58 mph (93 km/h).
Derecho
rotating column of air, in contact with the earth’s surface, pendant from a cumuliform cloud, often visible as circulating debris/dust at the ground.
Tornado
rotating cloud associated with a cumuliform cloud, not in contact with the ground.
Funnel cloud
six-level numerical, damage-based classification of estimated wind speeds, usually applied to tornadoes.
Enhanced Fujita Scale
rain that falls in liquid form but freezes upon impact to form a coating of glaze upon the ground and on exposed objects.
Freezing rain
rain that freezes into solid ice pellets before hitting the ground.
Sleet
snow with a water equivalent ratio of 10:1 or less.
Heavy, wet snow
standardized on-scene incident management approach that allows responders to adopt an integrated organizational structure equal to the complexity of and that meets the demands of a single incident or multiple incidents, without being hindered by jurisdictional boundaries.
Incident Command System (ICS)
to fix something in the mind or habit pattern by repetitive instruction, in this case, storm response procedures..
Storm drill
designated location where personnel and equipment are gathered and prepared for deployment.
Staging area
in utility arboriculture, pre-arranged cooperation between utilities to ensure a certain level of response is available in the event of emergencies.
Mutual assistance program
the probable track of the center of a tropical cyclone based on forecasts from the previous 5 years, with an accuracy rate of approximately 67 percent.
Track forecast cone
storm response handled entirely by locally based personnel.
Small-scale response
storm response requiring movement of crews from outside the immediate vicinity, often for an extended period, and therefore including the need for temporarily housing and feeding response personnel.
Large-scale response
movement of personnel and equipment into place prior to a storm strike.
Pre-staging
list of the people or things that belong to a particular group, team, etc.
Roster
proclamation by a government that releases resources (e.g., funds, personnel, or special procedures) or otherwise hastens the response to a disaster
Disaster declaration
pruning to redevelop structure, form, and appearance of topped or damaged woody plants.
Restoration pruning
natural or man-made occurrence disrupting the normal conditions of existence and causing a level of suffering that exceeds the capacity of adjustment of the affected community.
Disaster
__________ freezes solid before it hits the ground; __________ remains in a liquid state until it freezes on contact.
Sleet
freezing rain
The __________ is a systematic method for command, control, and coordination of emergency response.
incident command system

emergency operations center
Personnel from external organizations who travel to a storm area are generally paid the higher of either their __________ rates or the established __________ rates.
home pay
local pay
In the United States, the National Hurricane Center track forecast cone is intended to predict the track of a storm with an accuracy rate of _____ percent.
67
Removal of __________ following a storm is typically the responsibility of the customer.
brush
A safety __________ is a proactive measure in which all operations are brought to a halt until relevant safety information can be provided to response workers.
