<br />SCRIPT-TASK A. WARNING AND EVACUATION <br />(You have 10 minutes to read the s~ript.) <br /> <br />Slide A1. Task A. Warning and Evacuation <br /> <br />Most floods arrive with some warning. A well-prepared response to a flood warning <br />can save lives and prevent property damage. In Task A you will decide how to respond <br />to a flood warning that (community) just received, that the <br />River will crest at about 9:30 this morning. <br /> <br />Slide Al. Woman with child watching storm clouds <br /> <br />Here you see a woman holding a child and watching with worry an approaching storm. <br />The most basic warning system is simple observation. Typical river and stream <br />flooding is preceded by unusually long or intense rainfall. Heavy rain means large <br />amounts of water entering rivers and streams. Rising water levels are readily observed <br />by anyone. <br /> <br />Slide A3. National Weather Service office <br /> <br />However, it is risky to rely just on personal observation. Sometimes flooding can occur <br />from rainfall elsewhere in the watershed. Personal observation will not tell you how <br />much of the rain will flow into the stream, when the flood will reach its peak, or how <br />high it will be. Fortunately, the National Weather Service has a system for issuing flood <br />warnings which relies on scientific observations of rainfall and runoff patterns. Here <br />you see a Weather Service office where the information is collected and analyzed. The <br />Weather Service notifies your state emergency management agency when a flood could <br />occur. This is called a "flood watch." It also issues a "flood warning" when flooding is <br />imminent or already happening. The state notifies you if it has received a "watch" or <br />"warning" affecting your community. You may also receive the notification directly <br />from the Weather Service. <br /> <br />Slide A4. Form for an official flood warning <br /> <br />This shows the form used for an official flood warning issued by the National Weather <br />Service. The warning tells when and where flooding is expected. Sometimes the <br />warning predicts the height of the expected flood in feet above "flood stage." Someone <br />in your local government is designated to receive the warning and take appropriate <br />actions. It may be the city manager, the police chief, or your local emergency manager. <br /> <br />Script-Task A <br />
