Comparable NWS hydro products include:Urban and Small Stream Flood AdvisoriesFlood Watch / Flash Flood WatchFlood Warning / Flash Flood WarningPlain language is used with F2P2 MESSAGES to indicate imminent vs. potential flood threats.District local governments are familiar with this program and the practice of using MESSAGE Numbers 1-4.Potential Flood ThreatMESSAGE 1 (Street Flood Potential)This message is used to inform key people that weather conditions are such that low impact nuisance flooding could develop later in the dayaffecting streets, low-lying areas, normally dry gulches, small streams, and recreational trails along small drainage channels. Mud/debris/rockslides are the primary concern for the mountains and foothills, particularly for locations in and downstream of recent wildfire burn areas. Message 1 is the most common F2P2 message. In an average year, 30 to 40 days call for issuance of this message. When the threat of nuisance flooding is imminent, this message with include the sub-titleLow Impact Flooding more about this later.PMS refers to Private Meteorological Service contracted by UDFCDPotential Flood ThreatMESSAGE 1 (Street Flood Potential) continued</p> <p>The NWS may refer to this type of flooding as low impact flooding, which means that expected flooding will be localized and not wide-spread. This type of flooding is not generally considered life-threatening. However, fast moving water even at relatively shallow depths of 2-feet or less should always be considered dangerous, particularly along rivers, streams, and normally dry gulches or drainageways.Potential Flood ThreatMESSAGE 2 (Flash Flood Watch)</p> <p>This message is to inform key people that Flash Flood Watch has been issued by NWS and that weather conditions are such that a life-threatening flash flood may occur later in the day. Significant stream flooding and property damage is possible should storms develop. PMS will add any additional information that is available. Imminent Flood ThreatMESSAGE 3 (Flash Flood Warning)</p> <p>This warning message will be issued to inform key people that a Flash Flood Warning has been issued by NWS or PMS feels that a life-threatening flash flood is imminent. Significant stream flooding and property damage is expected. PMS will add any additional information that is available. This warning message should be disseminated as quickly as possible. Imminent Flood ThreatLOW IMPACT FLOODING (LIF)An LIF subtitle will be used when PMS believes that a nuisance flooding rainstorm is imminent. It will normally be issued as a MESSAGE UPDATE to a prior potential flood threat message (MESSAGE 1 or 2). However, storms can develop unexpectedly that may necessitate an LIF with the initial issuance of a MESSAGE 1. When a MESSAGE 3 is in effect, the LIF subtitle will not be used. If an approaching storm is expected to only cause nuisance flooding outside the warning area, plain language text in the MESSAGE 3 UPDATE will clearly indicate the nature of the threat. In summary, LIFs are short lead notifications of imminent nuisance flooding threats where the risk to life and property is considered low. LIFs should be disseminated as quickly as possible. Flood Threat EndedMESSAGE 4 (All Clear)</p> <p>This message cancels the flood threat status prior to its scheduled expiration. It is issued by PMS after consultation with NWS and other entities involved with direct PMS communications. </p> <p>NOTE: PMS will not issue a MESSAGE 4 when the current message is allowed to expire. The primary intent of this message is to notify jurisdictions of an early end to a flood threat.JULY 7, 2011UPDATERecommend updating the following slide series. The format has changed considerably.
