Hurricane Season etc.

Dr. Jeff Masters' WunderBlog has an excellent wrap of the various hurricane predictions with details and links.

"The high March SST anomaly does not bode well for the coming hurricane season. The three past seasons with record warm March SST anomalies all had abnormally high numbers of intense hurricanes. Past hurricane seasons that had high March SST anomalies include 1969 (1.06°C anomaly), 2005 (0.93°C anomaly), and 1958 (0.93°C anomaly). These three years had 5, 7, and 5 intense hurricanes, respectively. Just two intense hurricanes occur in an average year. The total averaged activity for the three seasons was 15 named storms, 11 hurricanes, and 6 intense hurricanes (an average hurricane season has 10, 6, and 2.) Both 1958 and 2005 saw neutral El Niño conditions, while 1969 had a weak El Niño. So, even if this year's El Niño lingers on into hurricane season, it may not protect us from a hyper-active hurricane season--the weak El Niño year of 1969 had 18 named storms, 12 hurricanes, and 5 intense hurricanes."
