The one item of note is that there is a notable lack of ‘wet’ seasons in the area for years <br />Figure 6 <br />when the PDO is in a ‘positive’ mode (ex: ), while the opposite can be said of <br />negative PDO years with a notable cluster of years with a strong negative PDO value. <br />Figure 6. April - June Precipitation in District 26 vs. the preceding November - January PDO value. <br />District 20 <br />The only HCI ‘predictors’ of note for the area was the ENSO indices (SOI and <br />MEI), which indicate a general trend of El Nino: normal-to-wet /La Nina: normal to dry <br />tendency. The ‘Atlantic’ HCI variables showed some promising but, mixed signals that <br />can not be endorsed as single index guidance at this time. <br />District 35 <br />Despite being on the other side of the valley from District 20, the ENSO <br />indicators appear to exert the same influence on the springtime precipitation as in District <br />20 with a general trend of El Nino: normal-to-wet /La Nina: normal to dry tendency. <br />An examination of the plotted correlations indicate that El Nino years have a tendency to <br />supply ‘adequate’ (80% of normal and above)precipitation with very dry springs tied to <br />La Nina years (please see Data Appendix for more information). <br />13 <br />
