<br />r <br /> <br />output, historic surface maps and obseevations a.nd experience gained from 11 <br />years of operational storm prediction in the UDF'CD F2P2. The resulting pat- <br />tern should be considered a conservative attempt at the reconstitution and <br />transposition of this storm. <br /> <br />The temporal and spatial distribution of rainfall for each storm over the <br />watershed in presented in Tables 6 to 8. Each table presents the average <br />subbasin rainfall for 10 minute intervals and a storm total rainfall for each <br />subbasin. These values were used as direct input into the basin model to <br />calculate basin discharges. In most cases the basin average rainfalls compare <br />favorably to the historic records. The exception is the Masonville storm for <br />reasons previously indicated. <br /> <br />Since the development of simple guidance for mountain flash flood warning <br />is a goal of this project, Table 9 of meteorOlogic data is presented which <br />could be of use to operational meteorologists within the UDFCD F2P2. The <br />table presents the observed vertical temperature, dew point and wind field <br />values for surface, 800, 700, 600, 500, 400, 300, 200 and 100 millibar levels. <br />Precipitable water from the surface to 500 millibars, presence of low level <br />convergence features and upper air triggers is also noted. CSR model output <br />of peak point rainfall for each storm is also presented. While this table is <br />not a direct forecast aid. it could be used to "red flag" conditions known to <br />have existed prior to and during several local severe flash floods. <br /> <br />It is beyond the scope of this project to develop forecast aids for the <br />meteorologist to deal with the rare, severe flash flooding threat of intense <br />thunderstorm complexes. However, a partitioning and archieval of upper air <br />observations similar to those in Table 9 and ohserved or predicted rainfalls <br />associated with severe events would be most useful within the F2P2. <br /> <br />FLOOD DISCHARGES FROl!
