www.lcra.orgColorado State ‘11 Hurricane Outlook
“We continue to foresee well above-average activity for the 2011 Atlantic hurricane season. We are predicting the same levels of activity that were forecast in early April due to the combination of expected neutral ENSO conditions and very favorable atmospheric and oceanic conditions in the tropical Atlantic. We continue to anticipate an above-average probability of United States and Caribbean major hurricane landfall.
William Gray and Phil Klatzback, Colorado State University, June , 1st Update
16 Named Storms (normal is 9.6)
