This product is only available within an hour <br />or less of storm impact. Also, the ST is not prepared for storms that do not pose a <br />flood threat. An example of the StormTrak product can be found on page 73 in the <br />Technical Addendum. <br /> <br />Message Definitions <br />Standardized messages are issued to emergency communication centers in each of <br />the seven District counties. Dispatchers disseminate the information according to <br />SOP unique to each jurisdiction. Below is a description of different messages. <br /> <br />Message 1 (Internal Alert) <br />This is an advisory message which is meant to inform key people that weather <br />conditions are such that flood producing storms could develop later in the day. It <br />will be issued after coordination with the NWSFO-BOU. <br /> <br />Message 1 - Red Flag (Internal Alert) <br />This is an advisory message which is meant to inform key people that weather <br />conditions are such that flood producing storms capable of producing rainfall <br />equal to or exceeding 1.00"/30 minutes and is considered imminent. <br /> <br />Message 2 (Flash Flood Watch) <br />This message indicates that a Flash Flood Watch has been issued by the <br />NWSFO-BOU and/or that the F2P2 meteorologist feels the risk is high that a life- <br />threatening flood may occur later in the day. If it is determined that this watch <br />requires priority dissemination, it will be identified as a RED FLAG message. <br /> <br />Message 3 (Flash Flood Warning) <br />This message indicates that a Flash Flood Warning has been issued by the <br />NWSFO-BOU and/or that the F2P2 meteorologist feels that a life-threatening <br />flood is imminent. This warning message requires priority dissemination (i.e. <br />AUTOMATIC RED FLAG). <br /> <br />Message update <br />This message will be used to update any of the previous messages, particularly <br />in the event of a disagreement between the F2P2 meteorologist and the <br />NWSFO-BOU. For example, this message can be used to narrow a watch or <br />warning area as more information becomes available or to provide more site- <br />specific data and direction during an event. If it is determined that this update <br />requires priority dissemination by the communications dispatcher, it will be <br />identified as a RED FLAG message. <br /> <br />Message 4 (All Clear) <br />This message cancels the flood potential status. This message is issued after <br />coordination with NWS-BOU and other entities. <br /> <br />Criteria that prompts the issuance of each product <br /> <br />The F2P2 products are issued based on predicted rainfall criteria that were developed <br />by the UDFCD using sound hydrological practices under the assumption that the <br /> <br />18 <br />
